Fish Rock Cave

Fish Rock Cave, off the coast of South West Rocks near Port Macquarie, is one of Australia's most extraordinary underwater attractions. This sea cavern, stretching over 120 metres through a rocky island, is a mecca for divers and snorkellers seeking an otherworldly experience. The cave's two entrances create a stunning light show as sunlight filters through, illuminating the marine life within.

Highlights & What to See

• Dive or snorkel through the cave – Swim through the illuminated cavern, spotting grey nurse sharks, rays, and colourful schooling fish.
• Grey nurse shark aggregation – Fish Rock Cave is a protected habitat for these gentle sharks, often seen resting in the sandy gutters.
• Marine life diversity – Look for wobbegongs, cuttlefish, and sea turtles along the rocky reef outside the cave.
• Green Island – The cave passes right through this small island; climb the steps for panoramic coastal views.
• Historic South West Rocks – Explore the nearby Trial Bay Gaol, a convict-built prison with dramatic ocean views.

Suggested Time to Spend

Allow a full day for this experience. Most dive operators run half-day trips from South West Rocks, including gear and guide. A single dive inside the cave lasts about 30–40 minutes, but you'll want time to explore the surrounding reef. If you're snorkelling, plan for two hours on the water. Combine with a visit to the historic gaol or a coastal walk to make the most of the area.
