Liveaboard Diving in Australia

Diving in Australia is literally immersing yourself in an underwater paradise.

Liveaboard diving in Australia is a must for many divers', and when anyone considers Australia as their next holiday destination, it's impossible to overlook what is on offer underwater. With a coastline of over 25 000 kilometres, much of it in tropical and sub tropical waters, the 'lucky country' is blessed with outstanding diving, guaranteed to please all levels from a novice up to the most experienced. Diving in the Great Barrier Reef (GBR) in Queensland is deservedly on many people's bucket list, with countless stunning reefs to explore from the many dive tours available from Cairns and the surrounding area.

The best way to truly appreciate the World's largest reef system, is to set sail on one of many Cairns based liveaboards, which will propel you to areas of the outer reef, allowing you to avoid the sometimes crowded inner reef, and view beautiful unspoilt coral and a wide variety of stunning marine life. Dive cruises from Cairns will also take you to parts of the GBR situated in the aptly named Coral Sea, where the visibility (on average well over 40 metres) and diversity is simply breathtaking. Then there is the wreck of the SS Yongala, widely recognised as one of the World's best dive sites, combining history with marine life to an unparalleled level.


The main draw is, of course, the GBR. However, Australian diving and liveaboard diving are not limited to this corner of the country. Many divers head to the opposite coast in Western Australia, where the diving opportunities are again almost endless. Liveaboards here make it possible to dive into the less well-known and remote areas of Mermaid and Clerke Reefs in the Rowley Shoals, allowing access to some of the country's most pristine and thrilling marine parks.

Liveaboard Dive Trips in Australia

Liveaboard.com offers various vessels in Australia, from modern purpose-built dive boats to sleek, fast catamarans. Each boat has its own unique feel, ranging from 24m to 37m, and is able to host 20-48 guests. They all include A/C. and electricity, and several of our boats feature free internet, but please check this before booking.

Itineraries range from 3 day/2 night trips to the Outer Great Barrier Reef to the all-encompassing 8 day/7 night tours, which will sail you through much of what Queensland has to offer. Some itineraries even include a return scenic flight, allowing you to witness the route you have taken from the air.

Tours start in the early morning of the first day, and most operators offer a complimentary pick-up from your accommodation. To ensure maximum safety and comfort, the first dive is often a 'check' dive, enabling the crew to establish the group and individual diving level and, from there, tailor the trip to cater to everyone's needs. Don't worry; even this first dive will be on a beautiful and unspoiled reef, giving you a taste of what to expect in the following few days! Diving from an Australian liveaboard will introduce you to the vast biodiversity not found near shore, and regularly includes sightings of families of Potato Cod, Grey and Silver Tip Whaler Sharks, Hammerheads, Manta Rays, Humpback Whales, and Maori Wrasse, along with a stunning array of hard and soft corals. Depending on your choice of dive cruise, you may even be able to partake in Minke Whale monitoring!

Every effort is made to accommodate individual requests, and often itineraries can be adapted to include extra sites - although, as always, the crew will adhere to strict safety standards, and so each trip will depend on weather conditions and diver experience.

Dive Sites And Areas of Australia

The Great Barrier Reef is the World's largest coral reef system and the largest living organism, stretching for 2300km along the coast of Queensland. It consists of over 2900 reefs and 900 islands, including the stunning sites of the Osprey Reef, Ribbon Reef, Milln Reef, Flynn Reef, Cod Hole, Lizard Island, Bougainville Reef, North Horn, and the SS Yongala wreck. Most of these locations are only accessible via a liveaboard tour departing from the port of Cairns.

Osprey Reef is in the Coral Sea section of the GBR and accessible via liveaboard from Cairns. Famous for its 40m+ visibility, the reef features many small caverns, swim-throughs, and almost guaranteed sitings of several shark species at North Horn.

Ribbon Reef is a 175km line of 10 individual reefs lying to the north of Cairns, which are quite isolated and only reachable via a few liveaboards. Due to their remoteness, these reefs offer sheltered, warm waters and are in pristine condition.

Milln Reef is located around 60km offshore from Cairns and includes 3 large coral pillars known as the three sisters. The area is great for snorkeling and diving; your crew may arrange a night dive for you, where you'll likely see sleeping turtles and crabs.

Flynn Reef offers diving for all levels and is best known for its coral garden - one of Australia's finest, featuring a stunning array of hard and soft coral.

Clerke Reef offers an opportunity to explore the underwater world of the Rowley Shoals Marine Park, where crystal-clear waters and abundant marine life create a diver's paradise. This remote reef system, accessible only by liveaboard, promises dive sites featuring pristine coral gardens, wall dives, and encounters with diverse marine species.

Cod Hole lets you get close to the huge but friendly and docile Potato Cod, which has a habit of posing for the camera! Other attractions here include Maori Wrasse and Moray Eels. This dive site is located north of the Ribbon Reefs and will often form part of a Ribbon Reef liveaboard.

Lizard Island is an island of the unspoiled national park and the most northerly resort on the GBR. Our liveaboards often involve a scenic reef flight either from Cairns at the start or back to Cairns from Lizard Island.

Western Australia diving is arguably as spectacular as that on the East Coast and may interest those divers interested in a less visited area of the planet. Liveaboards leave Broome in the state's northwest to access the truly unspoiled Clerke Reef and Mermaid Reef in the Rowley Shoals.

Rowley Shoals are a series of three coral shelf atolls 250km west of Broome that attract divers from all over due to their uniqueness. Along with their stunning coral gardens, there are over 650 species of fish, many of which are not found near the shore, so they can only be viewed from the luxury of a liveaboard boat.

When To Go

Diving on the GBR is great all year round, with water temperatures ranging from 24c in the winter (July/August) to 30c in the summer (December/January). Minke and Humpback whales can be seen between June and November, whereas the summer offers the best visibility and warmest waters to take advantage of the array of life on the reef.

The best time to visit the Rowley Shoals in Western Australia is September to December. Early booking is advised because diving via liveaboard is the only way to explore these pristine reefs.

Tips For Travelers

  • English is the native language of Australia, although many liveaboard operators have crews capable of communicating in many common languages.
  • The local currency is the Australian Dollar, and most major international credit cards are widely accepted. ATMs are readily available (although not on board!)
  • Electricity is supplied via 3 pronged sockets of 230 volts (50Hz) - make sure you acquire the correct adaptor!
  • Most liveaboards can rent full equipment, but you must bring your certification and log book as part of the safety protocol.

How To Get There And Ports Of Departure

Most liveaboards to the GBR and the Coral Sea depart from and return to Cairns. Conveniently, Cairns has an international airport that is serviced by many carriers, offering direct flights to a huge number of international destinations. In the unlikely event you are unable to fly directly to Cairns, there are regular daily domestic flights from the well-known hubs of Brisbane, Sydney, or Melbourne.

On the West Coast, Broome is the main port for liveaboard trips to the Rowley Shoals and associated reefs. Due to its remoteness, direct international flights are less common. It does have an international airport serving a handful of destinations, but it is more likely that you will fly into the state capital of Perth, where you can easily catch a connecting flight to Broome.

Cairns and Broome are holiday destinations in their own right, each offering world-class hotels and resorts. From Cairns, you can easily access the stunning tropical Daintree rainforest and waterfalls in the Atherton Tablelands (Peter Andre filmed his famous 'Mysterious Girl' video here!).

Broome is on the edge of the world-famous Kimberley region, one of the most remote and spectacular areas.

Considerations

Australia diving liveaboards cater to all types of travelers, from the budget-conscious to the luxurious, with prices ranging from around US$150-300 per person per day/night. Please check with your chosen operator for any extra charges, as some areas of Australia require marine park fees, reef taxes, port fees, a fuel levy, and an environmental management charge.

Australia requires most international visitors to have a passport with 6 months validity and a valid visa. Please visit https://www.abf.gov.au/ to find out how to obtain the correct visa.

As always, appropriate travel insurance should be purchased before traveling.

We snorkeled. Could be better about informing the boundaries as definitely had both experienced and non-experienced snorkelers and my husband kept getting called back. One of the safety said if he had gone in another direction then he wouldn’t have been called back. One of the members of our group had a lot of trouble with mask fitting properly- most likely because of his size and beard. Frustrating to him and turned him off from snorkeling beyond the 2 out of 8 options. But overall - the majority of our group had a great experience snorkeling.

Very good equipment and guides for dives and snorkeling. We saw a lot of fish, turtles, sharks, rays, and coral, but the reefs are damaged from recent typhoon and a lot of the coral has died.

What to know about diving in Australia

Is the Great Barrier Reef safe to visit?

Yes, for the vast majority of visitors — reef sharks are shy, shark attacks are extremely rare, and licensed liveaboard operators monitor conditions daily. The main hazard is seasonal marine stingers (box jellyfish and Irukandji), present roughly from October to May, which a lycra stinger suit easily guards against. As of 2026, serious incidents remain rare relative to the millions of people who dive and snorkel the reef each year.

What animals live in the Great Barrier Reef?

The reef supports more than 1,500 fish species and around 400 types of hard and soft coral, plus six of the world's seven marine turtle species, dolphins, and dugongs. Liveaboard divers also regularly encounter over a dozen shark species — whitetip, blacktip, and grey reef sharks are the most common — along with manta rays on outer reef and Coral Sea sites.

How deep is the Great Barrier Reef?

Reef depths typically run 15-100 ft (5-30 m), with the seabed dropping away sharply into walls and channels at outer reef and Coral Sea sites. Most recreational dives sit in the 30-60 ft (9-18 m) range, while advanced, appropriately certified divers can go deeper on wall and drift dives offered by liveaboard operators.

Can you snorkel the Great Barrier Reef?

Yes — snorkeling is one of the most popular ways to see the reef, and most liveaboard diving itineraries build in dedicated snorkel time at shallow bommies and lagoons alongside the scheduled dives. No certification is required, just basic swimming ability and, during stinger season (roughly October-May), a lycra stinger suit.

When is the best time to dive the Great Barrier Reef?

May through August bring the driest weather and the clearest underwater visibility, plus a shot at swimming with dwarf minke whales in June and July on far-north itineraries. September through December offers warmer water and coral spawning in October-November, so the best window depends on whether visibility, whale encounters, or spawning events matter most to you.

Are there sharks in the Great Barrier Reef?

Yes, the reef is home to more than a dozen shark species, most commonly whitetip reef, blacktip reef, and grey reef sharks, seen resting on sandy bottoms or patrolling outer reef slopes. These species are shy around people and pose minimal risk — as of 2026, shark attacks on the reef remain extremely rare.

Can you swim in the Great Barrier Reef?

Yes, swimming is permitted throughout the Marine Park, and most liveaboard trips build in free-swim and snorkel breaks between dives. The main precaution is marine stingers during the warmer months (roughly October-May), when a stinger suit is recommended even for a casual swim.

How do you get to the Great Barrier Reef?

Most liveaboard trips depart from Cairns, Port Douglas, Airlie Beach, or Townsville, all of which are served by domestic flights from Brisbane and Sydney, with Cairns serving as the main international gateway for the northern reef and Coral Sea. From port, liveaboard vessels typically cruise 2-10 hours to reach outer reef and Coral Sea dive sites, depending on the itinerary.

How can you see the Great Barrier Reef?

Options range from day-trip pontoon tours and glass-bottom boats to scenic seaplane flights, but a liveaboard is the only way to reach remote outer-reef and Coral Sea sites, such as the Ribbon Reefs and Osprey Reef, that day boats can't reach. Multi-day liveaboard itineraries typically run 3-7 nights and combine several dives a day with snorkeling and night dives.

Can you scuba dive in the Great Barrier Reef?

Yes — the reef is one of the world's premier scuba destinations, with sites for everyone from first-time divers doing an introductory dive at around 26 ft (8 m) to advanced divers exploring walls and drift sites down to about 100 ft (30 m). Liveaboard operators generally require at least an Open Water certification for unguided reef dives, though many run beginner certification courses on board.

Can you visit the Great Barrier Reef?

Yes, the reef is open to visitors year-round and is easily reached from Cairns, Port Douglas, and other Queensland coastal towns via day tours or multi-day liveaboards. A reef tax (the Environmental Management Charge) applies to most tours and is typically included in the trip price as of 2026.

What sharks live in the Great Barrier Reef?

The most commonly sighted species are whitetip reef, blacktip reef, and grey reef sharks, plus the small, bottom-dwelling epaulet shark in shallow lagoons. Larger species such as tiger sharks and hammerheads are present in reef waters but are seen far less often on standard dive and snorkel trips.

Where should you stay to dive the Great Barrier Reef?

Cairns and Port Douglas are the most convenient bases, with the widest choice of day-boat and liveaboard departures to the northern reef and Coral Sea, while Airlie Beach is the gateway to the Whitsundays and southern reef sites. For divers who want to maximize bottom time, a liveaboard itself doubles as accommodation, removing the need for a land-based hotel during the trip.

What fish live in the Great Barrier Reef?

More than 1,500 fish species call the reef home, from reef staples like clownfish, parrotfish, and butterflyfish to larger species such as Maori wrasse, coral trout, and reef sharks. Liveaboard divers on outer reef and Coral Sea itineraries also regularly encounter pelagic species like tuna, trevally, and barracuda.

What is the water temperature in the Great Barrier Reef?

Water temperatures range from around 75°F (24°C) in winter (December-February) to about 86°F (30°C) in summer (June-August). A 3mm wetsuit is generally comfortable in the cooler months, while many divers get by with just a rash guard or a 1-2mm suit in summer.
