Scuba Diving at Busselton Jetty
Coral and sponge growth in temperate water, under one of the longest timber jetties in the world.
Busselton Jetty extends well over a kilometre into Geographe Bay, and the underwater structure at its seaward end carries growth that is remarkable for the latitude.
The jetty provides structure, marine life and relatively accessible diving in sheltered water, and the coral and sponge coverage on the piles is unexpectedly rich for temperate Western Australia.
Access logistics are a genuine part of the dive, since divers generally use the jetty train or arrive by boat rather than swimming the full length.
Recommended: Any certified diver; many suit supervised try-dives. What can I dive with my cert?

- occasional larger visitors in the bay
The diving itself is easy. The logistics are what require planning.
- access arrangements and permits
- transport along the jetty
- entry and exit points
- marine life and coral growth
- depth, modest throughout
- current and visibility
- night diving availability
The Leeuwin Current carries warm tropical water south along the Western Australian coast, allowing coral to establish well beyond where the latitude alone would permit.
Combined with the jetty's vertical structure and the shelter of Geographe Bay, the result is a habitat that has no natural equivalent nearby.
Access
- Access arrangements and permits should be confirmed before arrival.
- The jetty train carries divers and equipment to the seaward end.
- Depth is modest throughout, generally under 9 metres.
- Sheltered by Geographe Bay, so conditions are often good when the open coast is not.
Hazards
- boat traffic around the jetty
- fishing activity
- entanglement on structure
- the long distance from shore if access arrangements fail
