Meet the site
Adventure Bay is the great sweep of sand and rock on South Bruny's east coast, a place steeped in exploration history: Tobias Furneaux anchored here in 1773, James Cook in 1777 and William Bligh in 1788 and 1792, and the bay became an early whaling base. For divers it is the hub of Bruny Island, offering both easy shore dives and boat access to the more dramatic sites of the east coast. The Marine Life Network guide documents several dives around the bay. Quiet Corner, a sheltered spot with a thick Macrocystis garden, holds the iron ribs and anchors of the barque Natal Queen, wrecked in 1909; Penguin Island near the bay's southern end has a narrow, steep reef and shallow sea caves; and further south, Cape Connella and the waters beneath Fluted Cape have larger rocks and deeper, luxuriant seaweed. Typical reef fish include blue-throated and purple wrasse, leatherjackets, magpie and banded morwong and bastard trumpeter, and weedy seadragons shelter in the weed. The guide notes that the shallow reefs are heavily fished and speared, so fish can be wary near shore. Because the bay faces east, it is sheltered from the prevailing westerlies and often calm when the channel side of Bruny is choppy. There is no dive shop or air on Bruny, so bring filled cylinders from Hobart. Adventure Bay has accommodation, a store and cafes, and the Fluted Cape walk gives superb views over the bay and the sites below. It is an ideal base for a diving weekend combining shore and boat dives.
