It is Minke Magic time again. Divers, snorkellers and underwater photographers are all lining up to head out into the Great Barrier Reef to get up close with the Minke Whales. This special event happens for just two months each year. At this point it is not fully understood where the dwarf minke whales come from, or where they go to. What is known is that the travel through the deep waters of the Coral Sea (off the continental shelf) and then move into the shallower waters around the Ribbon Reefs for what appears to be a time of socialising. Experience a close encounter with Minke Whales is a special experience. Watch this great video for more information. If you wish to experience an encounter, make sure you travel with an operator that has a Minke Whale Permit. These operators all contribute to scientific research and our knowledge of Minke Whales, in addition they have signed up to a strict code of conduct to protect the whales and ensure encounters do not adversely impact their behaviour.

Cairns Underwater Film Festival 2011
This year the Cairns Underwater Film Festival (CUFF) is back and I am proud to be involved both as a board member and also a photo competition judge. Although one look at the prize pool is enough to make me wish I was entering! There are some incredible prizes on offer to top destinations. The underwater photography competition requires entries to be taken in the Great Barrier Reef and Coral Sea.
Previously the festival has been run as a business by Christian Botella, however this year he has handed the running over to a team (the CUFF board) of volunteers, which Christian is still a part of. The CUFF team then made the unanimous decision to volunteer their time and return all profit from the festival back to the community through donations to local marine conservation groups and other worthwhile causes. Please visit the CUFF website for more information on this years festival and also the photo competition.
The wish list…
Philippines, PNG (again), Truk Lagoon, Coral Bay / Ningaloo (in Western Australia), Wolf Rock (near Fraser Island on Australia’s east coast), the Yongala Wreck (again), Coral Sea, Fiji, Tonga, Raja Ampat in Indonesia. There are so many spectacular dive sites, both locally and internationally that I would love to dive and photograph. What is you dream list? Are you doing any this year?
Or perhpas diving and underwater photography for you is all about keeping it local? While I love heading out to explore new areas and see the differences in coral reefs and critters all over the world, the bulk of my portfolio will always be the Great Barrier Reef and Coral Sea. We are lucky in Cairns to have such a great marine backyard and with my underwater photography workshops getting more popular I am looking forward to sharing it with lots of people this year, along with working towards the protection of the Coral Sea. If you would like to know more about either the workshops or how you can help establish a marine park in the Coral Sea, please get in touch.
Migaloo – the White Whale
Humpack whales follow hot on the heels of Minke Whales on the Great Barrier Reef, just as one season is waning the other is building into full force and we love it! While diving on the Great Barrier Reef, getting to hear the ‘songs’ of humpback whales is a beautiful thing and sends a thrill up your spine. Bizarre hand signals to each other follow as divers try to make each other understand…”that is a whale singing, can you you hear it”. Often the whales sound so close you find yourself constantly looking over your shoulder for a glimpse in the blue, but they can be up to two miles away and you can still hear their beautiful songs.
One of the most famous (if not THE most famous) humpback whales is Migaloo – the White Whale. Each year the first sighting of Migaloo is reported from NSW, ‘Migaloo has been spotted off the coast’ and we in Cairns know they are on the way. However, this year it has been even more exciting as their have been multiple ‘white whale’ sightings. Is it Migaloo or is it his calf? According to the White Whale Research centre on the 27th June 2010:
“The White Whale Research Centre has received two sightings (one confirmed by photos) of a white whale from different locations with the distinct possibility we might have two white whales cruising up the east coast of Australia. In July 2008 we had reports of a white whale with black spots on its head and tail.This one, named Bahloo after an Aboriginal moon spirit, was first seen swimming off the Gold Coast. Little is known about Bahloo. However with the sighting of Fraser Island on Sunday 27th it has been confirmed it was Migaloo which therefore means the unconfirmed sighting of Cape Byron on the same day could be Bahloo.”
Migaloo was then spotted again on the 21/07/2010 off Port Douglas. There are now reports of a sighting on Monday 2nd August off Cairns near Green Island.
Once thought to be an Albino Whale, Migaloo is for the moment he is known as a “hypo-pigmented” humpback. Migaloo was first photographed in 1991 off Byron Bay. He was the first documented all white whale and his name was taken from the name aboriginal elders from the Hervey Bay area of Queensland used for ‘white fellas’. In 2004 researchers from Southern Cross University were able to collect DNA from Migaloo which confirmed he was a male, but which can also be used to compare against other white whales (such as Bahloo) to check for paternity.
Because Migaloo is so readily identifiable, and has caught the attention of people around the world, sightings can be reported to the White Whale Research Centre which maintains a log. These sightings then provide valuable insight into the migratory behaviour of humpback whales. Migaloo is part of the east Australian humpback population, now suspected to number around 11-13,000 individuals in 2010. This population was likely around 30,000 before commercial whaling began, but was possibly as low as 104 individuals after commercial whaling on humpbacks ceased in the 1960s
The White Whale Research Centre was setup to act as a central communication point between universities, locals, the press and the public. Its website maintains a log of ‘Migaloo’ sightings and is maintained primarily as a resource for children studying whales, or anyone who wants to know more about Migaloo. Please visit their website for more information: http://www.migaloo.com.au
Because Migaloo is such a unique whale he has special Queensland & Commonwealth Government legislation to protect him from harassment. For this reason all vessels including Jet-skis are prohibited from approaching Migaloo no closer than 500m and Aircraft no lower then 2000 feet. The Fine for breaching this law is $16,500.00 If you are lucky enough to sight MIGALOO in the wild and can report his location please contact The White Whale Research Centre Via mobile phone on 0415 748 143 or email details and photos to sightings@migaloo.com.au
The Best Diving on the Great Barrier Reef
“Where’s the best diving on the Great Barrier Reef?”
This is not an easy question. The Great Barrier Reef is over 2000km long and has 2900 reefs. With thousands of dives on the Great Barrier Reef, in many different areas, I still hesitate at the question. Here is a round up of some of the best diving and experiences to be had:
The Ribbon Reefs offer a diverse range of diving from coral gardens (such as Flare Point, Challenger Bay and the Cod Hole) to isolated coral pinnacles with large schools of fish, macro life and ‘hollows’ which contain sharks, stonefish, octopus and more. This area is really an underwater photographers delight; the biggest challenge is usually choosing which subject to photograph or for the SLR photographers the agonising choice of which lens wide angle or macro. The Ribbon Reefs are a unique form of reef only found north of Cooktown. This section of reefs is very remote and therefore only extended liveaboard trips from Cairns run by Mike Ball Dive Expeditions, Taka or Spirit of Freedom visit this region. Nimrod Explorer and Undersea Explorer have both ceased operating. Day trips are available from Lizard Island, but only as a guest of the resort.
Dive sites on the Ribbon Reefs include: The Cod Hole, Steve’s Bommie, Pixie’s Pinnacle, Flare Point, Challenger Bay, Lighthouse Bommie, Acropolis, Two Towers, Snake Pit and Clam Gardens.
Marine encounters can commonly include: potato cod (aka 200kg fish), turtles, sea snakes, leafy scorpionfish, pipefish, white tip sharks, schooling trevally, nudibranchs, lionfish, stonefish, wobbegongs (carpet sharks), grey reef sharks and much, much more.
The Minke Whales make a guest appearance on the Ribbon Reefs from May to August, however the heart of the season (last two weeks of June and first two weeks of July) produce the most spectacular encounters with the highest number of whales. Interactions can include over ten whales and it is not uncommon for the whale to approaching within touching distance. There are few experiences underwater that can match the thrill of being eyeball to eyeball with a Minke whale.
The Cod Hole diving with 200kg fish which are quite happy to approach you, swim alongside you or let you sit quietly beside them is quite something. These fish are quite literally the same size as a human. Some operators run feeds where you can see these normally very tranquil fish move with impressive speed, power and agility. If you are lucky enough to do a night dive at the Cod Hole you will find the cod join you for a dive so they can use the light from your torches to hunt.
The Coral Sea actually starts where the Great Barrier Reef ends. It was named by sailors because they kept bumping (quite unfortunately for them) into isolated coral reefs which appeared to dot this area. We now know these as isolated oceanic mountains which raise up spectacularly from the depths to within a couple of metres of the surface. These reefs are shaped by the strong currents and upflows that contribute to the spectacular life which you can find on them. Osprey Reef is the most commonly dived Coral Sea reef, as it is serviced by the diving liveaboards from Cairns. Less commonly visited are Bougainville and Shark. Holmes and Flinders Reefs are accessed from Townsille.
The Whistunday Islands would often not be included amongst the ‘best diving’ category. The reef is fringing reef and visibility is affected by the land. However they are an absolutely beautiful set of islands and Whitehaven Beach is consistently voted as one of the best beaches in the world. In addition, nearby Hardy Reef (part of what has become known as the ‘Outer Reef’) does offer some good diving. So a trip to the Whitsundays on a boat which takes in all three of these areas is a brilliant experience.
Shark Dive at North Horn, Osprey Reef even through the Coral Sea is no the Great Barrier Reef, I am going to include this here as to get to the Coral Sea, you must go through the Great Barrier Reef and this dive is available on dive liveaboards which also access the Great Barrier Reef. North Horn is an amazing diving in its own right. With spectacular walls dropping down hundreds of metres and huge soft corals that remind me of fireworks with their display of colours, form and complexity. Add to this a large number of sharks and some tuna heads to attract them in for a close look and this is one spectacular dive experience.
Yongala Wreck is a dive that will blow you away and leave your neck sore from head swiveling. All you will do is want to go back for more. The wreck lies on a sandy bottom at 30m (rising to within 15m of the surface). The abundant marine life will keep you fully occupied and the wreck almost becomes secondary. However, it is an advanced dive and can be difficult to access as it is very weather dependent. Yongala Dive and Adrenalin Dive both operate day trips to the wreck.
Minke Whale Magic – Underwater photography of whales up close
Minke Whales – Images by Xanthe Rivett
I recently had the amazing fortune to spend time in the water with a Minke Whale. While encounters like these often involve multiple whales, this particular whales was on its own. Within minutes of entering the water the whale had approached us, at times passing close enough to touch. As its huge eye glided past regarding us carefully, we could only imagine what it was thinking! The interaction appeared to be fueled by a mixture of curiousity and playfulness.
I have had the good fortune to experience a few encounters with minke whales, but not for a couple of years. To be back in the water and see one, literally ‘face to face’ was a beautiful experience. The encounter was onboard Taka Dive Expeditions..
Photographing the Minke Whales
Entering the water on snorkel is your best opportunity for photography. Many marine animals are wary of bubbles and Minke whales are no exception. Underwater photography of Minke Whales can be tricky as they turn up on the Great Barrier Reef during ‘Trade-wind’ season. Strong winds can ensure a choppy sea and days maybe overcast and dark. The whales more than make up for the not-so-pleasant weather however, when bouncing around on a choppy sea with low-light, photography can be more challenging! Set your ISO manually so that it doesn’t automatically shoot up and cause unnecessary noise. Be careful of your exposures too as the whales are dark, as can be the water, and you want there to be contrast between the two. The Minke Whales also have patches of white on them which can burn out easily if overexposed, so pay attention to your highlight warning. Finally, either take your strobes off or ensure they are turned off…you they are unnecessary and you do not want to spook the whales.
How can you experience an encounter with a Minke Whale?
Minke whales migrate to the northern or ‘Ribbon Reef’ section of the Great Barrier Reef each year. They cruise through the Coral Sea and enter the Great Barrier Reef through deep channels or breaks in the ribbon-like reefs which give this area its name. Mike Ball Dive Expeditions, Taka and Spirit of Freedom all operate diving liveaboards in this area, and from which you may have the opportunity to see whales. Mike Ball Dive Expeditions and Taka offer dedicated Minke Whale expeditions during peak season. Day trips, while they advertise minke whales, are very unlikely to have a high chance of success to see the whales. Your best opportunity is to join a liveaboard for the last two weeks of June or first two weeks of July and your best chance to get up close to the whales is to be on snorkel.
Of the three dive liveaboards I would recommend:
1) Mike Ball Dive Expeditions first as it is the best quality liveaboard, they run dedicated minke whale expeditions, have experienced and knowledgeable crew and have been very strong supporters of Minke Whale researchers from James Cook University. In addition their fly/dive itineraries maximise time at dive sites which gives you more opportunity to spend time with the whales. The downside is the price as they are the best quality liveaboard operator on the Great Barrier Reef (as evidenced by the chocolate they put on your pillow after your daily cabin service) this may not suit everyone’s budget.
2) Taka (operated by Deep Sea Divers Den), their Friday trip departs for the Coral Sea and Ribbon Reefs which means that you have the opportunity to experience the Ribon Reefs, Coral Sea and Minke Whales! This is an amazing trifecta. However in a short trip you will have limited time to experience each which can be a compromise. Their Tuesday trip stays on the Ribbon Reefs which maxmises your opportunity. The crew are more laid-back and with a different price point to Mike Ball Dive Expeditions there is a different level of boat, food and customer service. They also have to drive the boat to and from Cairns in one trip which means more travel time. However the atmosphere is fun and is more budget-friendly.
3) Spirit of Freedom. They do not have a minke whale permit and have not supported the minke whale research in the past, but as a last resort this is your third option. I do strongly object to the fact that they do not have a permit, I believe they should contribute to the development of sustainable tourism practices rather than just take advantage of others doing the work for them.
Sustainable tourism and Minke whales. Researchers from James Cook University, along with liveaboard operators (such as Undersea Explorer which is sadly closed now) worked together over many years to learn more about these beautiful animals and their interaction with dive boats. What makes these interactions special is that the whales approach the boats. In many areas of the world where whale tourism is conducted the boats seek out the whales. Dive operators on the Ribbon Reefs simply tie up at one of their normal dive sites and the whales seek out the interaction. This also means that if you are a keen diver you can enjoy a top dive while waiting for the whales rather than sitting around on deck.
To ensure that the interactions remain positive for humans and whales alike, a code of practice has been developed.
The sad news is that Minke Whales are one of the species of whales still hunted. It hurts to think that this beautiful animal could be hauled up onto the deck of a factory ship next summer and sold for meat.
Types of Great Barrier Reef Dive Trips
Types of Dive Trips
Following is a basic break-down of the types of dive trips available on the Great Barrier Reef, including: day trips, overnight trips (distinct from liveaboards), sail / dive overnight trips (offer diving but not dedicated to), liveaboard trips and special expeditions.
Day trips:
These, as the name suggests, are trips which head out and return in one day. There are many, many, many, many available on the Great Barrier Reef. To decide which is for you consider whether you want:
- Long or short travel time. A long travel time can either mean a more remote reef or a slower boat, have a look at the maps and listed destinations for an indication. There are some situations where you can have a great boat which gets you quickly to a more remote reef. A few that spring to mind are Silverswift, Silversonic and Reefquest. However if you suffer from sea sickness, any extra time getting anywhere is not great so you may want to look at boats which travel to closer dive destinations.
- Size of vessel. The type of boat you take to the Great Barrier Reef can affect: stability, number of other passengers and speed. A boat up to 15m is on the smaller side and will have fewer passengers (examples include: Mantaray, SeaStar, Yongala Express). A boat 15-25m is mid-range and will have (generally) no more than 100 passengers (examples include: Tusa5, OceanFreedom, Reefjet). Above 25m you will have the bigger boats that can carry up to 300+ people. This sounds like a lot, and it is, but read on below to see that there can be some advantages to this in the facilities and activities they can offer. Not totally related to size of vessel but worth considering is whether you prefer catamarans or mono-hulls.
- Passenger numbers. As mentioned these can vary from 10 – 300+ on a day trip! As you can imagine the style of trip is hugely affected by this variation.
- 10-20 passengers. There is a scale of economy when it comes to running a boat. More people = bigger boat and / or the more fuel you can burn. If someone charges more, than this affects the equation, but it is a fairly safe rule to follow. What this generally means is that the day trips with lower passenger numbers a) have smaller boats, b) do not go as far, c) do not go as fast and d) are often more relaxed as crew are not trying to get large numbers of people safely in and out of the water within the set timeframe of the day. Often these vessels travel to more inshore reefs. An exception to the rules is DiveTime out of Airlie Beach and Yongala Express from Ayr. These are two boats which are small but fast and dedicated to diving.
- 20-100 passengers. This may seem like a very large range to cover in one category, but there is a reason for this. Many of the boats that carry a maximum of 50, 60, 70 or 100 passengers often only carry that number for a few peak weeks of the year. Outside of that time you may find yourself on a boat with only 30 or 40 people. At these times you have lovely big boat, fast engines and not so many people. These are the boats that are of the right size and with the right quantity of crew to be able to cater for a number of divers. However, they are not dedicated dive boats (if their is an exception I am not aware of please let me know but I am yet to find it!). These boats cater to snorkelers, introductory divers and certified divers. This means that if you are traveling with a non-diver they are happy, however the choice of dive sites are limited to ones which are also suitable for snorkellers and larger numbers of people mean the diving will be from the boat and back to the boat. Examples include: Reefquest, Silversonic, Poseidon, Silverswift, Reefjet, Tusa 5, OspreyV and many more.
- 100-300+ passengers. These are the big boats. They cater to big numbers and have big setups to go with them. They do not have a dive deck on the boat, but instead moor to a pontoon which is where the diving and snorkelling is conducted from. This means they are traveling to the same site each day (and then staying in that location) or they have a choice of two sites (for different weather conditions). The pontoons often also have semi-submersibles, glass-bottom boats and helipads which cater for those that don’t wish to get in the water. Surface-supplied ’sea-walks’ can also be offered such as at Green Islands ‘Seawalker’ facility.
- Location. Check the geography section for a list of port towns that access the Great Barrier Reef. There are no two sections of the Great Barrier Reef that are the same and each area has its pros and cons. In general the majority of travelers and divers visit the Great Barrier Reef from Cairns. The further north you travel along the Queensland coastline, the closer in to shore the Great Barrier Reef comes, which means reduced travel time. In addition, in this area the Great Barrier Reef itself is narrower. This means that it is easier to get to the outside edge of the Great Barrier Reef system, which has become known as the ‘Outer Reef’. The theory behind this being a superior area to dive is a) it is flushed with the clear waters of the Coral Sea, b) further from land means less disturbed by humans and therefore healthier and c) due to the geography of the reef itself there are more spectacular reefs in this area. Now I am not entering into a debate on these points (especially ‘b’). There are many examples of spectacular, healthy ‘inshore’ reefs. Likewise if an operation does not educate its dive instructors (and passengers) on how to protect the reef and/ or over use one of their dive sites on the outer reef, it will show the signs. However if you were going to speak generally, then the above is true. Closer inshore reefs however can offer sand cays and islands which are great for those that want to stretch their legs or view the bird life, they are very scenic and can offer more protected diving. The compromise is there though, in general the diving is not quite as good.
- Dedicated dive boat or not. The distances that boats travel to get to the Great Barrier Reef and back during a day has meant a trend towards larger boats and increased passenger numbers and a decrease in the number of boats which cater specifically for divers. It is not uncommon for a dive boat from Cairns to cover 60 nautical miles in a day. While a mixed-use dive boat will have the disadvantage of choosing dive sites that are also suitable for snorkeling, the majority of reefs on the Great Barrier Reef come within 1-2m of the surface (depending on the tide). Which means the restriction is not that great. The biggest effect will be on the style of diving you are able to do. Generally: drift dives, wall dives, isolated pinnacles and ‘wild-side’ diving are out and instead you will be diving from the boat in a sheltered ‘bay’ made by the reef.
- Price. At the end of the day everyone has a budget and the trip you choose will reflect that. In recent years the competitive nature of the Queensland dive and tourism industry has meant that some operators have chosen to include less in favour of a lower ‘ticket’ price. Whether this was a consumer driven decision or not, it does mean that, when comparing companies, you need to ensure you have a price which includes: EMC (or ‘reef tax), gear hire charges, fuel surcharges, port levy, transfers,etc. Day trips to the Great Barrier Reef can start from as low as AUD$69 and reach over the $400 mark. Some introductory dives are free, others can cost $150. Look at prices carefully.
- Customer Service and Reef Education. A great crew can make all the difference. Smiling, happy, professional crew who enrich your day are not just the icing on the cake but the filling inbetween also! A well-run operation look after their crew, educate their crew and choose good, experienced crew in the first place. This is something that you cannot tell easily from a website or brochure but it can make all the difference. In addition if some time is taken during the day to tell you more about the reef or explain to you what you are seeing this can really increase your appreciation of your day out. At the moment, in my honest opinion, there is no good measure in place to help you measure the quality of the crew on a given boat. The only thing that will do that is word of mouth or a recommendation from a trusted source. You can however, check the brochure to see whether a ‘reef talk’ is given onboard and if you have a recommendation after a great experience. Post it here!
Overnight Trips
Okay, let me explain why this is a separate category to ‘liveaboards’. Firstly, there are a number of types of overnight trips and they can be from 1 – 100+ nights long. This is because they transport you by plane, boat or helicopter to a boat, pontoon or island where you can stay indefinitely and then return you via a separate transport again. A ‘liveaboard’ is a boat you depart on, live on, dive on and return on; and which are dedicated to diving.
- Island stays. The Great Barrier Reef has over 900 islands and 27 which support resorts. Some are better dive destinations than others. Lady Elliott is the southernmost island/coral cay on the Great Barrier Reef, located east of Bundaberg. Nearby is Heron Island, they both offer diving from shore and boat. The Whitsunday Islands are a group of 74 islands with 9 resorts on 7 islands. Further north are Magnetic Island (off Townsville), Orpheus Island, Dunk Island (off Mission Beach), Bedarra Island, Fitzroy Island, Green Island and Lizard Island.
- Overnight boats. These are boats which stay in a relatively small area, and which you are transferred to either by helicopter or day boat. They offer increased flexibility in duration as you can choose the length of your stay, however they are restricted to an area within reach of the dayboat which arrives each day from Cairns. The restriction in movement also means that they are restricted to a small group of dive sites without the ability to do the more remote diving of a liveaboard. However, this compromise comes at a lower price than liveaboard which access the remote areas of the Great Barrier Reef.
- Pontoon stays. This may not sound as glamorous as a resort island or overnight boat but the contrast between being out there with hundreds of people and then the quiet magic once everyone leaves…
Sail / Dive Overnight Trips
The Whitsundays have been a sailing mecca since the first cruising yachts found them, and stayed. Now Airlie Beach is the starting point for many sailing trips which head not just around the Whitsunday Islands but also to the ‘Outer Reef’ including Bait Reef. There is a large range in the type of sailing vessel, standard of accommodation and the quality/ standard of diving services. For a change in pace on your diving trip, this may well be worth an investigation. Trips are often combined with visits to one of the World’s most beautiful beaches – Whitehaven Beach. While not up to the high diving standards of the liveaboards which service the remote regions of the Ribbon Reefs and to the Coral Sea this is a different style of overnight diving trip.
Liveaboard Trips:
True dive liveaboard trips are dedicated to diving. Like all dive trips to the Great Barrier Reef there are varying standards of vessel, diving and service. The best indicator is price and destination. There are liveaboards departing from Airlie Beach, Townsville and Cairns. In the far north of Australia’s Great Barrier Reef the Ribbon Reefs are a remote area that only 3 dive liveaboards visit. These liveaboards also venture out into the Coral Sea to Osprey Reef. For experienced divers looking for high quality liveaboards, these are the trips you want to look at.
Special Expeditions:
Interested in a trip which is unique, a learning experience or contributing your time to make a difference through scientific research or conservation efforts? These are expeditions which do not depart every week, each expedition is unique (or at most only occur a few times a year) and ’special’ experiences that only a few will be lucky enough to participate in. Because of the diversity of these expeditions I will simply include here a list:
- Earthwatch. Work beside scientists on pressing environmental problems. 2010/2011 projects include: Project Manta (Lady Eliott Island) and Turtles in Trouble (Brisbane).
- Eye to Eye Marine Encounters. Minke whale and shark expeditions run to the Great Barrier Reef and Coral Sea. These expeditions are run in conjunction with organisations such as Australian Geographic.
- Mike Ball Dive Expeditions. A schedule of ‘extraordinary expeditions’ is run each year. These are run to the same high standard as their regular dive liveaboard expeditions but have either a unique itinerary of special focus.
- Cape York Turtle Camp. Okay this is not a dive trip, but still worthy of a mention as it would appeal to many people. This is an experience in a remote part of Australia that few ever travel to and a chance to help protect turtles.
This list ’scratches the surface’ but that is all. If you know of an expedition or organisation that runs expedition worthy of a mention, please let me know.
About the Great Barrier Reef and Coral Sea
The Great Barrier Reef is in one word ‘huge’. It covers around 20,000sq.km of reef surface and is only slightly smaller than Germany. That is a lot of diving. More than any of us will do in one lifetime. How do you choose where to go diving between the 2900 reefs and 940 islands?
Geography of the Great Barrier Reef
Starting at the town 1770 (where the Great Barrier Reef is youngest and named by Captain Cook after the year he landed there) and heading north 2000km to the tip of Queensland, Australia (where the Great Barrier Reef is oldest) there are several main port towns where you can access the Great Barrier Reef: 1770, Bundaberg, Mackay, Airlie Beach, Townsville, Cairns and Cooktown.
Most of the Great Barrier Reef is formed on the continental shelf, once the shelf drops away this is what most people consider the ‘Coral Sea’. The Coral Sea was named because of the isolated reefs that rise up from the deep ocean and caused significant issues for early maritime shipping in Australia’s waters. It was also home to the ‘Battle of the Coral Sea’ in the 2nd World War.
Of the reefs along the Great Barrier Reef there are several types: fringing reefs, ribbon reefs, platform reefs and deltaic reefs.
In the Coral Sea reefs are ‘oceanic sea mounts’ huge underwater mountains which can rise from over a 1000m deep to the sea surface.
Fringing Reefs are adjacent to the mainland or an island (which is different to a coral cay). This can mean there is a beach which you can dive or snorkel off, but it can also mean slightly reduced visibility due to the run-off from land. These include the reefs of the Whitsunday Islands.
Ribbon Reefs are found only in the northern (oldest) section of the Great Barrier Reef. They run along the very edge of the continental shelf and benefit from being flushed by tides with the clear waters of the Coral Sea. Due to their remoteness on a few dive operators visit the Ribbon Reefs which are all north of Port Douglas.
Platform reefs are some of the most commonly dived. They can be 3-10km long and often have a lagoon in the centre and sometimes also have a sand cay (which can overtime stabilise to the point of having vegetation on it like Low Isles or Green Island).
Coral Sea Reefs include Osprey Reef, Bougainville Reef, Flinders, Holmes, Wreck Reef and Lihou. Many are too remote for diving operators to visit.
Great Barrier Reef Marine Life and Seasons
o Minke Whales – May to August (prime season: Jun and July)
o Humpback Whales – Jun – September (prime season varies along the coast)
o Turtle Nesting and Hatching – Nov to March
o Coral Spawning – varies each year depending on moon phases but generally November on outer reefs.
Diving Conditions and Weather
Weather! Where do you start? Okay, firstly no one controls it. Mother Nature is amazing, spectacular, powerful and uncontrollable (although we do keep trying). Here is my weather forecast for your trip: sunny with a chance of wind, clouds and rain. I can very easily say some of my best and most memorable trips have been in very poor weather conditions. We still went diving, the sea was still wet, the coral and fish were still amazing and we saw incredible things we would not have seen if we stayed home or chose to wait for a ‘nice day’. We would have lost that opportunity and missed those incredible moments.
