Why dive here

What this place is known for

    Dwarf minke whale season

    Surprise relative to the headline, and a strong one. The Great Barrier Reef is a byword for coral, and the Ribbon Reefs hold the only predictable, permitted in-water dwarf minke whale interaction in the world, for two months a year. The whales approach the…

  2. Outer-edge ribbon reef system — diving at Ribbon Reefs (Northern Great Barrier Reef)
    02reef

    Outer-edge ribbon reef system

    The outer ribbons take clear oceanic water off the continental shelf and are in materially better condition than the inshore day-trip reefs out of Cairns and Port Douglas, which is the distinction almost no booking page draws.

  3. Cod Hole potato cod — diving at Ribbon Reefs (Northern Great Barrier Reef)

    Cod Hole potato cod

    Ribbon Reef No. 10. Very large habituated potato cod that approach divers directly. Historically a fed site; feeding is now restricted under Marine Park rules, so treat any 'cod feed' description with caution.
