Meet the site
Eddystone Rock is a granite reef system off Eddystone Point, rated 6 out of 10 by the Marine Life Network guide. It has shallow, wave-swept ledges and weed gardens in 6-15 m, with banded morwong, leatherjackets, trumpeter, long-snouted boarfish, crayfish and abalone. The guide notes that it has been heavily fished in the past, is exposed to easterly weather, and that bull kelp is a hazard - it can entangle divers and hide the reef in surge. It is usually dived as a boat dive paired with the more sheltered cove at the Eddystone boat ramp or with Picnic Rocks further north. Treat the depths, positions and conditions given here as a starting point, and confirm them with local divers and a depth sounder before committing to a dive.
The far north-east corner of Tasmania, from Eddystone Point to Cape Portland and Swan Island, is one of the most remote stretches of the state's coast. Roads north of St Helens and around Gladstone are partly gravel, the nearest shops are at Gladstone, Derby or Bridport, and there are no dive services at all. The Marine Life Network guide, written from the experience of Launceston divers, is still the only detailed published account of most of these sites.
Where Bass Strait meets the Tasman Sea around Cape Portland and the Swan Island group, tidal streams run hard, and the guide repeatedly stresses slack water, safety lines and experienced boat handlers for the wreck sites. The Royal Hobart Hospital chamber is five hours or more away by road, so any diving here should be conservative and planned with an evacuation route in mind.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Eddystone Rock is recorded as Reef in Tasmania North-East. 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.
- 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.
