Overview

Wild dolphins and dugongs by day, wall dives on the Indian Ocean edge when conditions line up

Shark Bay (Gathaaguda) is a remote, World Heritage listed corner of Western Australia where the water story is bigger than reefs. Monkey Mia is famous for its daily wild dolphin visits under ranger supervision, but the wider bay holds one of the planet's richest seagrass ecosystems, supporting dugongs, turtles, rays, and a long list of shark species. For divers, the signature adventure is a boat run out to the open-ocean edge at Steep Point and across to Dirk Hartog Island, where walls and sanctuary zones can deliver big-fish encounters when swell and wind cooperate. For snorkelers and freedivers, shallow sites like Eagle Bluff and Little Lagoon offer clear water, easy entries, and wildlife watching in just a few metres of depth. Topside, pair red dunes in Francois Peron National Park with Shell Beach and the ancient stromatolite story at Hamelin Pool.

What Makes It Special

  • World Heritage water story

    Seagrass meadows, dugongs, and ancient stromatolite systems make Shark Bay a destination where ecology is the headline, not just scenery.

  • Ranger supervised dolphin encounters

    Monkey Mia's dolphin experience is managed for animal welfare, with clear rules that keep interactions safe and ethical.

  • Remote, high-reward outer-edge diving

    Boat days to Steep Point and Dirk Hartog Island can deliver walls, bommies, and pelagic sightings, but require flexible planning around wind and swell.

  • Topside adventures that match the water

    Francois Peron National Park, Shell Beach, and Shark Bay's lookouts turn a dive trip into a full coastal expedition.
