Meet the site
Tin Mine Cove is the loneliest site in this list – a small beach on the north-eastern tip of the Prom facing Corner Inlet, named for a short-lived tin mine of the 1920s whose relics lie in the scrub behind the beach, and reached only by the Prom's northern circuit walk or by boat across the inlet. It sits inside the Corner Inlet Marine National Park rather than the Wilsons Promontory one, and Scuba Doctor lists it at 2–15 m for Open Water divers, noting that the site slopes off gently from the beach to a depth of 15 m about 50 m offshore, that snorkellers should walk to the point from the beach and scuba divers should anchor a boat next to the big boulder at the north end of the beach. The dive is a granite point and boulder slope dropping into the inlet's seagrass and sand, and the interest is the meeting of two habitats: on the rock, kelp and algae with wrasse, leatherjackets, zebrafish, old wives, abalone and small crayfish (protected), sponges and ascidians on the shaded faces; on the sand and seagrass, the inlet's nursery fauna of King George whiting, flathead, stingarees, pipefish, seahorses, cuttlefish and juvenile fish, with rays and the occasional smooth stingray in the channel. Corner Inlet's Posidonia seagrass meadows are the largest in Victoria and the park protects them; divers should keep off the beds. The deep channel just off the cove carries strong tidal currents and is the reason the dive is done at slack water and kept close to shore. Visibility is inlet-grade, a few metres to 10 m on a good neap. Nobody dives Tin Mine Cove regularly – it is a site for overnight walkers with a mask, or for a boat exploring the northern Prom from Port Welshpool – but it is a genuine wilderness dive in a park most divers never see, and a reminder that the Prom's marine parks include the sheltered inlet as well as the Bass Strait islands.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Tin Mine Cove is recorded as Reef in Wilsons Promontory. 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.
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.
