Into the Mouth of Fish Rock: A Certified Double-Boat Dive Through 10–30m Walls and a 26→10m Cave.
Fish Rock is world-renowned and consistently ranked among Australia’s—and the world’s—premier dive sites. This double-boat trip pairs an open-water dive on towering walls and bommies with a cave passage that runs from a deep entrance to a shallow exit, offering concentrated encounters with dense marine life across a 10–30 metre depth range.
Highlights
Outing Highlights
World-class Fish Rock
A site that lives up to its reputation: varied open-water topography — bommies, walls and passes — concentrated marine life and prominent named sites that make each first dive distinct.
Two Dives, One Cave Passage
A standard day is two dives: an initial open-water dive at one of several nearby sites, followed by a cave transit that typically runs from the deep entrance (~26m) to the shallow exit (~10m). The cave is introduced progressively and is not mandatory for every diver.
Certified, Prepared, and Geared Up
This adventure requires certification and specific experience levels; operators supply tanks and weights while other equipment must be brought or rented, with daily hire options available.

What the Day Feels Like
You meet at the dock to kit up and brief, then head out on the boat for two dives: a first drop into open water among aquarium-like bommies, gutters and walls, and a second, more focused dive that can include a cave transit from about 26 metres up to 10 metres. The operator tailors the day to diver experience, and the pace is set around safety briefings, rig checks and surface intervals on a five-hour schedule.
