Meet the site
The jetty at the northern end of Pirates Bay is the working heart of Eaglehawk Neck diving: the dive centre's catamaran and Go Dive Tasmania's seal-snorkel boat both leave from here. It is also a useful shore dive in its own right, especially for divers who want an easy first dive to check weighting and drysuit trim before the boat sites, or a night dive after a day on the water. The bottom slopes gently from the beach across sand and low reef to 8-12 m, with kelp and brown algae on the rocky sections. The main attraction is weedy seadragons, which the dive centre notes can be found around the peninsula all year and which frequent kelp-edge habitat of the kind found here. Around the jetty and reef edge divers also find wrasse, leatherjackets, stingarees and rays on the sand, cuttlefish, octopus, sea stars and nudibranchs. Night dives are productive, with octopus and crabs out hunting and fish asleep in the weed. Visibility is usually lower than on the outer coast, typically 5-15 m, because the bay is shallow and sandy. The dive is easy and forgiving, with no current and a clear reference in the jetty, and it suits beginners, photographers and anyone looking for a relaxed seadragon search. The main hazard is boat traffic: the ramp is busy with charter and private boats, so surface only along the edge of the reef away from the ramp and carry a dive flag. The jetty sits at the edge of the historic Eaglehawk Neck, where convict-era guards once chained a line of dogs across the isthmus to stop escapes from Port Arthur, and there are cafes and accommodation within a few minutes' drive.

- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
- 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.
