Being so rich in marine life, it is not just one of the best scuba diving spots in Australia but it has become one of the best diving destinations in the whole world. Much of the reef is also protected, which is why it is also one of the best dive areas in Australia. The Great Barrier reef is home to many shark species including whale sharks and hammerhead sharks. The reef is also a great opportunity to spot whales like the dwarf minke whales or sperm whales. Much other fish like barracudas, giant groupers, blue-spotted rays, turtles and parrotfish can be seen. Besides big pelagics, the Great Barrier reef has offered some beautiful healthy coral, great visibility, and numerous dive sites for different levels of divers. Even though it is highly popular among scuba divers and scuba snorkelling as well, there are also some great dive sites that are rarely visited.

There are several airlines that fly non-stop between Australia and the US. The airport in Sydney offers the best options for international and domestic flights. Perth, Melbourne and Adelaide also have many international flights. 

Continue your travels with a trip to neighbouring Thailand.



Although you can take day trips out to dive - in general, the further you go the better the diving becomes.  Due to this, liveaboards are typically better to properly experience what all Australia diving has to offer. In general, the Great Barrier Reef is the most popular, but the Coral Sea is better. Many divers will visit as part of an Australia packages tour, often stopping off at various dive sites around the country.



Besides numerous underwater adventures, the country itself has great topside activities being home to some gorgeous beaches, unique wildlife, mountains, and rainforests. Due to Australia's size, it is near impossible to cover all the things you can do while visiting Australia.  It is also dependent on what areas you are visiting. But to touch on a few; no trip can be complete without learning of Australia's Aboriginal culture, try taking a hike to the sacred site of Uluru to catch the sunrise or sunset. For you city lovers, climb the Sydney Harbor Bridge or see a show at the iconic Sydney Opera House.  Or just take a drive along The Great Ocean Road - a scenic drive you won't forget. Australia is an inspiring place to visit, find out all about it.

Flinders Pier - Western Port Harbour, Victoria, Australia.
Flinders is a favourite site of mine, approx 2 hrs drive from Melbourne situated just around the corner of Western Port Heads in a sheltered location. Parking can be a bit of a hassle if the day is quite hot especially on weekends. There is no where close to get air/nitrox fills so make sure that you bring enough tanks to last the day. There is a great bakery at the top of the hill (very steep) so grab some food there before you go down to the pier. Diving is mostly done under the pier with a max depth of 8mtrs at high tide (low tide - 2mtrs) therefore check to see what the tides are before going. Visibility can sometimes be a bit of a problem especially after a storm. But most times it is approx 15mtrs. Beware of fishermen also. There is two entry points 1st is half way down the pier at the lower landing (giant stride) or entry from the beach directly under the pier. Exit points are halfway along the pier at the ladder or back up the beach. This site is fantastic for macro photography with nudi's, blennies, sponges and feathers. In abundance are Weedy Sea Dragons and the pier is also home to nursery fish which are great for wide angle photos. There is also the resident Bull Rays 3 of them. I have had the opportunity of watching these rays during mating and it was truely amazing. This is an easy site for diving and the shallow depth gives a longer bottom time for those that are taking photos. There is a fair variety of different areas around and under the pier ranging from sea grasses to rocky bottom, nearly at the end of the pier is a old engine which has a lot of critters and fish living in it and just off the end of the pier is an old shipwreck (not much left of it now). I have dived this site now on numerous occassions and have seen newbie divers right up to more experienced divers with 100's of dives under their belts coming back and saying did you see that great ............. or saying what a fantastic site wished i had known about this years ago. I love taking divers there just for their reactions when they get out of the water and are eager to go back under. As for topside there is not much for you to do between dives, have a walk down the pier and chat to the fishermen, watch the hanggliders take off from the top of the cliff or go for a walk around the rocky headland (which is also a marine reserve have not dived there yet) or just laze about on the beach or under a tree whilst the non divers are cooking up a BBQ on the free BBQ's supplied by Council. The small town of Flinders is situated at the top of the hill with some good shops, eateries and pub. There is also a golf course for the non divers to keep themselves occupied whilst you are have a nice long dive. And finally for the kids there is heaps of australian wildlife for them to spot especially the wallabies and kangaroos.

The destination I will be discussing is specifically Cairns (pronounced Cans) which is one of the main points to the Great Barrier Reef. I also spent a small amount of time in Port Douglas which is the other main entry point and I will discuss the contrasts further down. The discussion is mostly about the place vs the diving as it was the first dive experience I had so my judgement is too newb for people looking for vast information on the diving. The city is located in the state of Queensland which is the Northeastern state. It is very close to the equator and is a hot and very humid place. I was there in their late winter early spring season and it was still in the high 80’s with 80% humidity. Direct flights to Cairns is available from most major cities, I flew from Sydney which is about a two hour flight.

If you are looking for a lot of night life and energy, Cairns is where you want to stay. It has no shortage of hotels and hostels available and the downtown boasts a large area for nightlife. It is the city where Australians come for spring break type activities and there are also a lot of European travelers. There was a lot of restaurants to choose from and plenty of bars to visit. *As a warning, the term hotel can be also applied to bars or pubs so you need to make sure your looking at the right thing when doing internet research*

Cairns is a major hub for reef diving and liveaboard boats. The service I used was the Silverseries and their boat the Silverswift, we went out to the outer reefs. The boat was a spacious catamaran style boat which was configured with a spacious back deck for dive gear and a retractable platform which allowed easy entry and exit for snorkelers and divers. The crew was very friendly and helpful and they provided everything you need for the day. The conditions were not great, visibility was about 50 feet which is not the usual but we were not there for the prime season. The life I did see included small fish like clownfish, schools of barracuda, one turtle that swam away very fast, giant clams, and lots of hard coral. Topside activities I participated in was a tour of the Daintree Rainforest (a World Heritage Site), a saltwater crocodile safari, a hiking tour of Mossman Gorge, and lounging at The Esplanade which is a public lagoon pool at the main park. There wasn’t any great stretches of beach there for people to spend time on.


Port Douglas is very different from Cairns because it is geared towards either an older crowd or people looking for a quiet experience. The downtown was small and very tourist oriented and there was dramatically less bars. Luxury resorts are more common here and the food options were pricier.

Overall this is a great destination for getting both the opportunity for topside activities as well as scuba diving. There are liveaboards available for more serious divers and plenty of services for the beginner diver or snorkeler. Also the local dive operators raved about using one of the operators to travel to the White Sundays (pronounced the Whit-Sundays). I mixed in my visit to Cairns while also visiting Sydney and Melbourne and it is very easy to reach Cairns from those cities.

Far Northern Great Barrier Reef, North of Cairns – Day Trips from Port Douglas & Liveaboards to the Ribbon Reefs

I have made this review to look at a few of the aspects of this area that I feel are glossed over in trip reports and other reviews that I have read. A quick google search will tell you all you could need to know about specific sites and the diving in general.


The city of Cairns in Far North Queensland may be the most well know dive spot on the Great Barrier Reef and a prominent fixture on the East Coast backpacker circuit. The diving here is affordable by Australian standards and gives a fair indication of what the Barrier Reef has to offer while great rates for Open Water tickets ensure that more new divers are educated than nearly any other part of the globe. The reefs visited, however, are often chosen more for their suitability for these new divers & snorkelers and are closer to shore to keep the trip times down.

For the more experienced diver a trip North of this area will really pay dividends and show what the Barrier Reef is famous for. Isolated Pinnacles swathed in glorious hard coral, bountiful pelagics, enormous fish & even Whale encounters in season. Every trip here will take you to the very outer edge of the reef with the majority of the top dives being conducted on pinnacles between slivers of reef called the Ribbon Reefs. Starting with Agincourt Reef (more on this below) in the south of the area, these long, thin reefs are roughly orientated on a North-South axis and mark where the edge of the Australian continent shelves off into abyssal depths. The proximity to the open ocean water of the Coral Sea ensures reasonably reliable visibility & fantastic encounters with some incredible wildlife.

Be advised that scuba diving here is expensive. A 7 day liveaboard here is comparable with a week on a mid to top level boat in Komodo or Raja Ampat, and a 3 tank day trip will set you back close to US$300. As a disclosure of my experiences here I should advise that all my diving was done as a volunteer on various boats, working for free dives – in the case of the day trips from Port Douglas I was able to dive the sites numerous times in different moon phases and experience them in every type of weather & current. I was here over ‘the wet’ – Australia’s summer – where the conditions can be less than ideal, though I was rarely left in port due to inclement weather and never experienced a bad dive. The boats used here are sturdy, comfortable and most have stabilising features; however even so, those prone to debilitating seasickness would be well advised to keep a good eye on the conditions.

Port Douglas Day Trips:

Port Douglas is an old fishing village cum glitzy resort town on a spit of land protruding out from the area’s rainforest clad mountains. The vast majority of the accommodation here is in big name resorts and can be reasonably affordable for those wishing to live the pampered life for a week. There is also a large backpacker/dive themed hostel there for the more adventurous travellers who want to get away from the (admittedly so much fun that it should be illegal) Cairns hostel world. There are regular busses from Cairns and some of the operators will pick you up in their own company coaches. The price is only marginally more expensive than the Cairns boats and I would really advise everyone to head up here.

The Operators here tend to either visit the Agincourt complex of reefs, which are more numerous and in my opinion feature more varied and superior quality diving or Opel Reef to the south – though my favourite ever Great Barrier Reef dive, Split Bommie, is on Opel Reef but was unfortunately rarely visited in my time there. The moorings are privately registered with the QLD government and though a couple of the operators have agreements on shared usage of sites they do not swap reefs. A cursory glance on each companies’ website will confirm which reef they visit.

Most of the boats will feature a mix of snorkelers & divers and will visit 2 or 3 different sites in a day with both groups exploring the same site. One of the largest companies out there, Quicksilver Cruises, has a different approach; they maintain a static, floating pontoon to which the majority of the snorkelers and families are taken while a separate boat ‘Silverswift’ goes out with divers and more adventurous snorkelers and visits a selection of sites. All boats provide buffet lunches and are large enough for everyone to be able to sit comfortably at a table throughout the day when not in the water.

The sites in the Agincourt group are largely based around big bommies in the lee of the reef with slack currents and a few drift dives when water movement allows. You can expect to encounter plenty of Grey Reef Sharks, large predatory Groupers & Trevally and what I think of as one of the best aspect of diving in Australia: edible fish. Having spent a lot of time diving in Asia I love to come back to Australia and regularly dive with animals that are non-existent elsewhere. This is particularly true of the Agincourt Reefs; Napoleon Wrasse, Spanish Mackerel, Tunas, Giant Trevally, Barramundi Cod & more Coral Trout than you can shake a stick at. It is only once you have spent time on a truly healthy reef that you realise how much even the finest sites in most of Asia lack these animals.

By contrast, Opel reef is a separate large oval reef. Dives here are what I consider to be classic Barrier Reef dives; along the edge of the reef from 20 metres depth working up to the reef flat. It has great hard coral cover and looks fantastic in the shallows with the sun out. The aforementioned ‘Split Bommie’ site is set back slightly from the reef proper and features two large pinnacles joined at the base in around 30 metres of water. Being more irregular that the main reef the bommies feature plenty of nooks and hiding holes for a variety of creatures including two of the largest Cuttlefish I have ever seen. I’ve also heard talk of visits from Hammerhead sharks from time to time.


Liveaboard Trips to the Ribbon Reefs:

This is where the real magic happens. There are currently 3 operators regularly offering 3 day, 4 day & 7 day trips up to the famous ‘Cod Hole’ based at Ribbon Reef #9, off-shore from Lizard Island with the 4 & 7 day trips then heading out to the open ocean to visit the very sharky Osprey Reef in the Coral Sea for some good shark diving. The more pricey companies will fly you either to or from Lizard island for the 3 day & 4 day trips where the 7 day ones will start and finish at Cairns. I’m not in possession of the required robustness of bank account to have visited Osprey Reef but I can wax lyrical all day about the Ribbon Reef portion of the trips. You can expect anything and everything to turn up on these trips if your luck is in. Additionally, I think I enjoyed the feeling of travelling through and diving reefs that s2ee very little action as enjoyable as the dives themselves.

The sites are similar to those mentioned above but are deeper, the water clearer, the predatory fish bigger, schools of fish larger and feature far more of the little creatures than further south. My personal favourites are ‘Steve’s Bommie’ – though I think this is everyone’s favourite - and ‘Pixie Pinnacle’. Both are huge pillars of coral set back in the blue in between gaps in the Ribbon Reefs. Whilst on Steve’s Bommie I looked up from admiring a Frogfish & a couple of Stonefish to see the biggest Grey Reef shark I’ve ever witnessed swimming past. A special mention for night dives here – with the floodlights on at the rear of the boat night dives turn into carnage with bait fish attracted to the light and then brutally slaughtered by Giant & Black trevally and the odd shark. I was lucky enough to see a couple of enormous free swimming Moray Eels join the fun at one point too. All this with weather so bad we couldn’t even make it up to the Cod Hole.

Though the experience of these trips is very weather dependent and the financial outlay considerable I would still suggest a visit to anyone who appreciates witnessing a healthy reef system complete with all the top predators, coral in great condition and the feeling of scuba diving somewhere remote.

Brisbane, QLD


Situated in Northern New South Wales (NSW), Byron Bay is the name of both a small town & Bay approximately 772 Kilometres North of the state capital of Sydney while only 165 Kilometres South of Brisbane, the capital of the state of Queensland (QLD). Cape Byron at the South Eastern end of the Bay is the Eastern most point of the Australian mainland. The whole surrounding area is part of the 'Tweed Volcano', a shield Volcano that was once over 100 Kilometres in diameter. The remains of this ancient volcano are plainly visible on any raised-relief map and have provided fertile soil, mountains & rainforests to both Southern QLD & Northern NSW.

Famed for its relaxed atmosphere, alternative lifestyle pursuits and particularly for the quality of the surfing, Byron Bay has become a renowned tourist destination and essential stop off on the 'backpacker circuit' of East Australia.
Originally named Cavvanbah, meaning 'meeting place' by the local Aboriginal tribe, Captain Cook was the first European to encounter the bay in 1770 which he then named after British naval officer Vice Admiral Officer.

The focus of the scuba diving from Byron Bay is conducted on nearby Julian Rocks, a collection of sedimentary rocks that break the surface approximately 2.5 kilometres offshore from Cape Bryon. The Rocks are the remains of an ancient volcanic eruption and said to be a continuation of the mainland. The area was declared a part of the Julian Rocks Nature Reserve in 1961 with the immediate surrounds of the rocks being further progressed to a no-take sanctuary in 2006.
The waters around Julian Rocks host a meeting of tropical & temperate waters supporting a diverse mix of species allied to both. Life on the rocks follows two distinct seasons; Winter brings sub 20 degree temperatures, endangered Grey Nurse Sharks, migrating Humpback Whales and the odd Seal while in Summer the water warms to a maximum of 25 degrees and Leopard Sharks & Reef Mantas (Manta alfredi) are regularly encountered. Throughout the year you will find a cast of at least 2 types of Wobbegong, Green and Loggerhead Turtles; Schools of Red Snapper, Jew Fish (Mulloway) & hundreds of smaller fish. The substrate of the rocks host innumerable sessile species and amongst them an outstanding collection of invertebrates. Visibility tends to hover in the 8-15 Metre range with higher or lower possible but rare. The dive operators report clear visibility results in a lot of the fish life hiding from view and I can certainly offer a few anecdotes of Sharks and huge schools of fish suddenly appearing out of nowhere in low visibility. Best visibility is tide & swell dependant but a 'South Easterly' wind and swell is generally an indicator of good diving conditions. The local divers are rightly very proud of the environment in their backyard and host an invaluable website describing every possible species of life on the rocks -

The underwater environment is composed principally of rocky reef starting where the rock breaks the water line and gradually descending to a sandy floor of varying depths. The rock is laced through with dramatic canyons, trenches and boulders, all covered in a clover-like leaf - for which I cannot seem to find a name - and interspersed with any number of tunicates, corals, anemones & hydroids. As stated above, the meeting between tropical and temperate waters gives Julian Rocks a remarkably high level of diversity; I have seen it best described recently as a struggle in determining if it is a tropical location with touches of temperate life or vice versa.

Some of my favourite dives here are:

Hugo's Trench - a deep cut in a ridge of the rock that not only harbours an enormous school of 'Stripey', heaps of Pufferfish & the amusing, endemic, Pineapple Fish but also the most varied and populous collection of Nudibranchs I have witnessed anywhere. Yes, I am a Nudi tragic - guilty - and no, I have not had the pleasure of Anilao just yet, but I would say it even rivals Bali if you can convince the operator to leave you in the trench while they do the circuit of the sights on this particular dive. note: This is not how I like my diving to be carried out but it seems to be the prevalent way to lead a dive in Australia and is certainly necessary when the visibility is low.

Nursery - This site is on the North of the rocks and is shallower at an average of 10-15 metres. More about relaxing and watching than tearing through currents chasing fish or sharks, this site is where I've regularly encountered an enormous Loggerhead Turtle and is also home to some very large Snapper in mid-water.

Cod Hole - Best dived with current coming in from the South East I've always started this dive around the corner at depth. The sight when you do round the rock into the current is extraordinary; enormous schools of Jew Fish up to a metre in length, Snappers & all sorts of other large fish all pointing into the current. It was here, with visibility below 5 metres, that I suddenly came face to face with a charging 2 Metre+ Grey Nurse Shark while trying to work out where my group had gone. The side of a sharp rocky reef, facing the wrong way in the current, lost & only giant fish for company is unsettling at best. I've never had so much fun.

Dive trips are offered by a number of operators in the town. All trips are for 1 tank only and return back to base for surface interval if you are enjoying multiple dives in one day. The conditions in the bay are unsuitable to the construction of a permanent jetty with all operators using large RIB boats to launch out through a surf break at the East of 'Main Beach'. This involves launching the boat on the beach, diving into it and then firing a loud horn to scatter the surfers before powering through the surf. The surfers don't appreciate the interruption but it's great fun for us divers. I have encountered schools of Bottlenose Dolphins playing in less than 2 metres of water here, which is obviously a wonderful to start or end the trip. Once clear of the Cape the boat is immediately subjected to open ocean swells, and as such dive trips out can definitely be 'bouncy' though even in the worst conditions will not take longer that 25 minutes. There are great sites round the entirety of the rocks so regardless of the prevailing weather there is always a sheltered place to dive. Diving will rarely be cancelled, and only then when safety is endangered.

Finally, I cannot do justice to the broad topside options here. With the beauty of the rainforests inland, the wonderful food and the delightful accommodation options, Byron Bay is a genuine gem and a perennial favourite for locals and tourists. So much so that diving here is far from the primary reason to visit for the majority of visitors. Book a few extra days and stay to relax while you dry off.

Great Barrier Reef and Ningaloo Reef - a general overview of the scuba diving:


Coendozn's review of the Great Barrier Reef is pretty close I think. Perhaps he (or she) hasn't been brutal enough in saying that if you are an advanced diver, don't go on a trip to the inshore reefs, and particularly don't go on a scuba diving trip that is still teaching students. The further out reefs, and more expensive tips, are the ones to go on.


Ningaloo Reef (on the other side of Australia - the west side) also has some great great diving. You can dive out of Exmouth, or out Coral Bay, which is about 150km south of Exmouth. Ningaloo is about equivalent to the outer reefs of the Great Barrier Reef. It is more wind dependent, but all reefs are close to shore and are done as day trips. Not lots of night life, but enough. Good onshore facilities and good dive operators.

The Elbow at Coral Bay is amazing sometimes. Pretty often really amazing. Big animals, sometimes bigger than you might prefer. I had dives there on consecutive days with amazing mantas barrel rolling so close that you could have touched them sometimes.

The whale sharks are a seasonal thing, and it is just snorkeling. It can be expensive but worth it as a one off. Whale shark season is about March to maybe June or July, it can vary.

Exmouth has more sites than Coral Bay and more options if the wind is from the west. It also has some good hiking in the ranges nearby. It is not quite like Colorado, but you wouldn't have come to Australia for Colorado scenery. On that subject, the land based activities in the Cairns and Port Douglas areas are excellent, and much better than in the west.

A trip combining Exmouth and Coral Bay would be a very good trip.

Coral Bay and Exmouth get seriously hot in our summer (Dec, Jan, Feb). Think in terms of hotter than Texas in summer.
