Bare Island
Sydney's most-dived shore site — weedy seadragons, extraordinary macro life and multiple routes.
Bare Island at La Perouse is one of Australia's best-known shore dives and the centrepiece of Sydney's Botany Bay diving. On a weekend morning the car park is a reliable meeting point for half the city's divers.
The site offers several distinct routes at different depths, which is why it sustains that popularity — divers who have dived it a hundred times still find new things.
Weedy seadragons are the headline species, and Bare Island is one of the most reliable places in the world to see them. Beyond that, the macro diversity is exceptional: nudibranchs, pygmy pipehorses, anglerfish, octopus and a long list of cryptic species.

- eastern blue gropers
Bare Island is best thought of as several sites sharing a car park. Each route has its own character and its own conditions window.
- the left side — shallower, sheltered, good for training and macro
- the right side — sponge gardens and seadragon habitat
- the deep route — out to around 20 m over sand and sponge
- the isthmus — shallow and often used for skills
Bare Island is where a large proportion of Sydney divers learn, practise and keep diving through winter. It is sheltered, accessible, free and rewarding.
It is also a useful demonstration that a site does not need clear tropical water to be world-class. What it has is biodiversity.
Weedy seadragons are protected and are easily stressed by crowding and repeated strobe flashes. They move slowly and cannot escape attention easily.
Keep a respectful distance, limit photography time per animal, and never move or handle them.
Access
- Shore entry from the causeway area at La Perouse.
- Several entry and exit points serving different routes — left, right and deep.
- The walk in is short but involves steps and uneven rock.
- Sheltered from most swell directions, which makes it diveable when the open coast is not.
Hazards
- boat traffic in Botany Bay
- fishing line and discarded tackle
- surge at the entry points in swell
- slippery rock on entry and exit
- navigation, since the site is larger than it looks
