Fish Rock essentials

Address: South West Rocks / Arakoon, New South Wales, Australia

Fish Rock is a rocky island and submerged reef standing offshore from South West Rocks, set against the coastal landscape of New South Wales. The rock and its surrounding reef rise from deeper water and form a compact but complex dive site with ledges, overhangs and swim-throughs.

The feature sits close to the headlands and beaches protected by Arakoon National Park, and the area is known for coastal wildlife both above and below the surface. Visiting the rock is mainly an activity for divers and boat-based wildlife watchers rather than beachgoers, and most visits are organised through local dive operators operating from South West Rocks.

  • Shark and pelagic encounters: Fish Rock is renowned among divers for regular encounters with larger fish and sharks around the caves and ledges, attracting underwater photographers.
  • Underwater caverns and swim-throughs: The reef includes submerged caverns, tunnels and overhangs that make for dramatic diving topography and sheltered spots for marine life.
  • Boat approach and headland views: Approaching from the water offers striking views of the rocky headlands and the coastline of Arakoon National Park.
  • Coastal birdlife: Seabirds and coastal species can be spotted on the rock and nearby headlands, especially during calm weather.
