Dive sites · 2026 guide
These sites keep most of the dive within the 18-metre limit of an Open Water certification, usually with sheltered entry and manageable conditions. They are also good for getting comfortable again after time out of the water.
Conditions on the day matter more than the site's reputation — dive with a local operator or guide if you are unsure.
1Sydney, New South Wales
Sydney's most-dived shore site — weedy seadragons, extraordinary macro life and multiple routes.
The site offers several distinct routes at different depths, which is why it sustains that popularity — divers who have dived it a hundred times still find new things.
Look for: Eastern Blue Groper, Giant Australian Cuttlefish, Nudibranchs, Port Jackson Shark

2Cairns, Queensland
The reef systems reached daily from Cairns — the most-dived section of the Great Barrier Reef.
Coral cover, fish density and crowding vary considerably between them. The reefs closest to port see the most traffic; the outer reefs generally offer better coral and clearer water in exchange for a longer steam.
Look for: Green Turtle, Queensland Groper

3Ningaloo & Exmouth, Western Australia
A fringing reef close enough to shore that in places you can swim to it from the beach.
For certified divers, the reef systems and offshore sites around the Exmouth Gulf provide the main scuba product, with drift diving along the reef edge and coral bommies inside the lagoon.
Look for: Green Turtle, Humpback Whale, Manta Ray, Spotted Eagle Ray
4Fleurieu Peninsula, South Australia
South Australia's best-known leafy seadragon site, beneath a long jetty on the Fleurieu Peninsula.
The old jetty's T-section at the seaward end is the main attraction. The structure carries dense growth, and the piles and their surroundings hold the seadragons the site is known for.
Look for: Giant Australian Cuttlefish, Leafy Seadragon, Striped Pyjama Squid, Weedy Seadragon
Diving Adelaide5Yorke Peninsula & Edithburgh, South Australia
One of the world's great muck dives — an unremarkable jetty hiding extraordinary small life.
Jetty sites are often described as easy because access is from shore. That can be misleading, and Edithburgh illustrates why: shallow does not mean trivial, and the best diving here happens at night.
Look for: Giant Australian Cuttlefish, Leafy Seadragon, Nudibranchs, Seahorses & Pipefish

6Gold Coast, Queensland
An aquatic reserve off Tweed Heads with a resident turtle population and seasonal grey nurse sharks.
The protected status has produced habituated marine life, and divers regularly encounter multiple turtles on a single dive.
Look for: Green Turtle, Grey Nurse Shark, Humpback Whale, Leopard Shark (Zebra Shark)

A protected sponge garden at Nelson Bay with some of the richest macro life in Australia.
The sponge gardens hold an extraordinary density of small life, and the protection means the fish are habituated and the habitat is intact.
Look for: Nudibranchs, Seahorses & Pipefish
8Whitsundays, Queensland
Sheltered island reefs — the diving most Whitsundays sailing trips actually visit.
They are where most Whitsundays in-water activity actually happens, and they suit introductory diving and snorkelling well.
Look for: hard coral, Maori wrasse, batfish, turtles, reef fish
9Ningaloo & Exmouth, Western Australia
A structure dive with extraordinary fish density, on Defence land with controlled access.
The structure supports an extraordinary density of fish — grey nurse sharks, wobbegongs, giant groupers and vast schools crowded into a comparatively small area.
Look for: Grey Nurse Shark, Nudibranchs, Queensland Groper, Wobbegong

10Sydney, New South Wales
An Eastern Suburbs shore dive with a long-established underwater nature trail.
The boulder terrain and kelp hold a solid range of temperate species, and the bay is sheltered enough for comfortable diving in most conditions.
Look for: Eastern Blue Groper, Nudibranchs, Port Jackson Shark, Wobbegong

11Ningaloo & Exmouth, Western Australia
Offshore islands north of Exmouth with coral gardens and reliable clarity.
Sites include coral gardens, bommies and swim-throughs, with turtles and reef sharks common.
Look for: Manta Ray, Whale Shark

Tens of thousands of giant Australian cuttlefish gathering to breed in a few metres of water.
South Australian tourism information identifies the main aggregation period as approximately May to August. The animals gather over shallow rocky reef within metres of the shore.
Look for: Giant Australian Cuttlefish
