Meet the site
Fish Rock is Bicheno's best-known shore dive: a large granite spire standing about 75 m offshore at the edge of the reef in front of the breakwater, split almost in two and with a large cavern on its shore side. The Combined Clubs guide describes an 8 m boulder split through its centre surrounded by weedy reef, and the Marine Life Network guide rates it as an excellent day and night dive with a safe breakwater entry and exit.
The weed and cray-weed beds around the rock are the place to look for pot-bellied seahorses and weedy seadragons, and cuttlefish, octopus and southern calamari are frequent, especially at night. Mackerel, trumpeter and banded morwong school around the spire, while tunicates, sponges and sea spiders cover the rock faces. The maximum depth is about 15 m, and most of the dive is spent at 6-12 m.
Because it can be reached from the shore in a short swim, Fish Rock is a common training site and the standard way to finish a Bicheno trip once the boats are packed away. It is also one of the few places in the area that can be dived independently without a boat. The rock sits at the edge of the Gulch approach, however, so divers should tow a flag or stay deep enough to avoid boats.
Fish Rock and the adjoining Waubs Bay dive (which follows the sand edge west to the split bommie known as The Rock) are often combined on one long dive. Together they are the most accessible diving on the Tasmanian east coast and a good way to see the east coast's seahorses and seadragons without leaving the shore.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Fish Rock (Bicheno) is recorded as Shore/Rock Platform in Tasmania East Coast. The listed access is shore or boat. Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
