Meet the site
Deep Glen Bay cuts into the Forestier Peninsula north of Pirates Bay, and its northern side forms a wall that is one of the most frequently dived sites on this stretch of coast. Local photographers describe it as a 'Sisters lite': the wall merges into the coastline and carries colourful sponges, sea whips and invertebrates, but it sits in a more sheltered position, so it is the site operators use when the weather is not cooperating offshore. Go Dive Tasmania rates it at 10-40 m with sheer walls, excellent visibility and a good chance of weedy seadragons, while the Marine Life Network guide describes a reef extending seaward with narrow ledges and caves, sponges, hydroids and gorgonians in about 30 m. The Tasmanian Scuba Diving Club notes steep underwater cliffs, boulder fields and kelp forest. The Divers Alert Network's account of diving here with Mick Baron and Karen Gowlett-Holmes singles out the North Wall's tapestry of invertebrates and fish, including Shaw's cowfish, banded morwong and rock lobster. New Zealand fur seals are regular visitors, weaving through the kelp at the top of the wall. The flexibility of the site is its strength. Newer divers can stay at 12-18 m along the upper wall and still see plenty of colour, while Advanced and Deep divers can drop to 30 m and beyond where the sponge and sea-whip gardens become denser. Weedy seadragons are found on the kelp and sand edges in the shallower sections. Visibility is often excellent because the site is washed by clean coastal water. It is a reliable, varied dive that many visitors end up doing more than once.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Deep Glen Bay North Wall is recorded as Wall in Tasman Peninsula. The listed access is boat (day trip). 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.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
- Overhead environments
- Ask whether the plan stays entirely in open water. A wreck or cave listing is not permission or training to enter.
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.
