Scuba diving Australia is amazing. If you’re travelling on the East Coast, you’ll have opportunities to enjoy some of the world’s best scuba diving sites. Here’s the ultimate list of the best diving sites in Australia (Queensland & New South Wales) with quick notes on why they made it to the list.

If you’re after the map of the best diving sites in Australia (for the East Coast), scroll down to the end of the article.

I have dived most of these scuba diving sites (in bold in the list), sometimes multiple times, and loved it. I’d be happy to scuba dive again on any of these sites.

The best scuba diving sites on Australia’s East Coast: Cairns / Brisbane / Sydney

The order is from North to South in reference to the map below – and not by order of preference. Luckily, scuba diving Australia provides a great variety of diving sites. Hence, these sites are very different from each other, so it’s hardly impossible to classify them by order of preference. It all depends if you prefer coral reefs, sharks (perfect for your adrenaline bucket list!), manta rays, seals, seahorses or macro photography.

Are you covered for scuba diving by your travel insurance? It’s worth double-checking. If not, I recommend DAN (Divers Alert Network) for those who dive regularly. WorldNomads* and Covermore* also make it easy to add adventurous activities like scuba diving to your plan.

1. Osprey Reef: Amphitheatre shark frenzy, rare Osprey Nautilus, pelagics.

2. Cod Hole: Meet friendly giant potato cods (up to 100kg).

3. Cairns/Outer Great Barrier Reef: The world’s largest coral reef system.

4. SS Yongala: A wreck dive on the Great Barrier Reef with amazing marine life. I recommend leaving from Ayr.

5. Heron Island: One of Cousteau’s top 10 dives on the Great Barrier Reef.

6. Lady Elliott: Manta rays and turtles in pristine waters on the Great Barrier Reef. If you can only do a day trip, check out Lady Musgrave Island.

8. HMAS Brisbane: Easy open wreck fun to explore even for beginners.

9. Minjerribah (Stradbroke Island): Manta rays and leopard sharks in summer, grey nurse sharks in winter and turtles all year round

If you cannot make it to the Great Barrier Reef and would like to see some corals, add Flinders Reef in Moreton Bay (accessible from Brisbane) to your list.

10. Julian Rocks: Grey nurse sharks in winter, leopard sharks in summer and turtles all year round, near Byron Bay.

11. Pimpernel Rock: A fantastic dive site when the conditions are right, you’ll have to be lucky. But the plan B, a dive in the Solitary Islands, is good too.

12. Fish Rock Cave: One of the longest caves you can dive with a basic open water certification, near South West Rocks. Grey nurse sharks wait for you at the exit. Hammerhead sharks are sometimes spotted.

13. Lord Howe Island: An unspoiled island with rivers of fish

15. Broughton Island: Plenty of grey nurse sharks hidden within schools of smaller fish, not far from Nelson Bay and Port Stephens.

16. The Steps: A shore dive with 99% chance of seeing weedy sea dragons – we saw one after three minutes! Weedy sea dragons can only be found in Australia southern waters, so it is rather special.

17. Jervis Bay: Seals and Port Jackson sharks in winter, and you can also spot weedy sea dragons there.

18. Montague Island: We saw seals underwater and cute little penguins on the island.
