Weatherhead Point is on the western, sheltered side of the Freycinet Peninsula, across Promise Bay from Coles Bay. The Marine Life Network guide rates it 6 out of 10 and describes a volcanic reef running along dolerite cliffs, with a shallow, sheltered dive of 6-12 m.

The dolerite here makes a change from the granite typical of the rest of the Freycinet coast: expect columnar, blocky rock and ledges rather than rounded boulders. Brown algae cover the reef, with leatherjackets and wrasse the most common fish. The guide notes that the site is often dived on the return journey from Schouten Island, as it is close to the route back to Coles Bay.

Although it is not spectacular, Weatherhead Point is a dependable second dive, sheltered from the prevailing easterly weather on the ocean side. It suits Open Water divers and allows a long, relaxed profile.

As with all Freycinet diving, there is no operator or air in Coles Bay, so divers must arrive with their own boat and equipment. The Freycinet coastline above water is spectacular from this angle, with the Hazards and Mount Graham towering over Promise Bay.

Some context helps set expectations for all Freycinet diving. The peninsula's pink granite continues under water as rounded boulders, cracks and steep faces, and the area sits where the warm East Australian Current meets cooler southern water, so species lists mix typical Tasmanian fish with more northern visitors. Over recent decades warming water and grazing by the long-spined sea urchin, which has spread south from New South Wales, have thinned kelp beds along the east coast, and descriptions written in the 1990s may not match what you find today.

Coles Bay is 30 minutes south of the Tasman Highway via the C302 (turn off 12 km south of Bicheno), about 2 hr 45 min from Hobart and 2 hr 30 min from Launceston. The main public boat ramp is at Coles Bay township; boats reaching the ocean side of the peninsula or Schouten Island need a seaworthy vessel, as the run around Cape Degerando or through Schouten Passage is exposed. From the Coles Bay ramp head south across Promise Bay to Weatherhead Point, about 15-20 minutes.

The site is often dived on the way back from Schouten Island.

On the western side of the peninsula, Weatherhead Point is sheltered from the ocean swell and from easterlies, but exposed to strong westerly and south-westerly winds blowing across Great Oyster Bay. It is usually diveable when the ocean coast is closed by easterly swell. Rain washes tannin-stained runoff into Great Oyster Bay, and summer afternoons commonly bring a fresh north-easterly sea breeze, so plan dives for the morning.

Drop at the base of the dolerite cliffs and follow the reef along the point at 6-12 m, then turn and return shallower. An easy, sheltered dive suitable as a second dive. Turn the dive at half gas (thirds where current or overhead sections are involved), deploy an SMB before surfacing for the live-boat pick-up, and complete a 3-minute safety stop at about 5 m where depth allows.

No dedicated dive operator at Coles Bay or Freycinet. Sites are dived from private boats and occasional club expeditions (Tas Uni Dive Club, TSDC, Launceston clubs); the Marine Life Network guide notes that Coles Bay is the usual starting point for Schouten Island charters. Cruise and kayak operators in Coles Bay do not offer scuba.
