Point Lookout, Amity and Dunwich became North Stradbroke Island’s population centres.
During Logan’s time Dunwich served as a depot for supplies which were off-loaded there before being taken up the Brisbane River by shallow-draught boats. A quarantine station was established at Dunwich in 1849, barely in time to receive passengers from a fever ship and to bury several of the victims. In 1864 a benevolent asylum was added for aged and infirm persons, and in 1892 a lazaret (hospital for incurable diseases, mainly leprosy) was established. In between these events the quarantine station was moved to Peel Island, midway between Redcliffe and Dunwich.
The asylum consisted of numerous well-constructed buildings, with the dining hall being converted to a community hall well after the closure of the asylum in 1947. Less well constructed was the Aboriginal settlement Myora at Moongalba two kilometres north of Dunwich. The site includes the Myora spring, is an environmental reserve, and the last resting place of Aboriginal poet and activist Oodgeroo Noonuccal (1920-93), who was born on Stradbroke Island.
