Brisbane River and up to the penal settlement of Brisbane. The Dunwich settlement was in close proximity to a major Aboriginal camp at Myora Spring. Whites and Europeans generally lived in reasonable harmony though there were moments of conflict as would be expected within the context of two very different cultures meeting for the first time. Early efforts to establish agriculture on the island, especially plans to grow cotton north of Dunwich, resulted in conflicts with the local Aboriginal people, the Ngugi tribe of the Quandamooka people. In March 1830, the 57th regiment seeking reprisals for the murder of a guard, attacked a group of Ngugi people near a lagoon on Moreton Island. This was likely the first significant massacre of indigenous people in the region. In 1843 the first Catholic mission for Aboriginal people was established on Stradbroke Island by Archbishop Polding, a Passionist priest, who visited and chose the site. It was unsuccessful because of poor relations with the local tribes and lack of resources, and the missionaries withdrew in 1847. A quarantine station was established at the northern end of the island in July 1850. This was due to its proximity to the shipping route, its isolation and to there being a supply of fresh water available. On 2 February 1887 the barque Scottish Prince ran aground on the southern end of Stradbroke Island. Three tug boats were dispatched to try to pull the vessel free, but this did not succeed. All of the passengers and crew were rescued but the cargo was remained onboard until the ship broke apart and its goods were washed ashore. Parts of the wreck can still be found in shallow water approximately offshore south of the Southport Spit and it is a popular diving site. Since 2013, sand movement has resulted in increasing amounts of the wreck becoming visible. Myora Mission, initially run by the Queensland Aboriginal Protection Association from 1892 and from 1896 by the Queensland Government as an Aboriginal reserve and "industrial and reform school", was used as a source of cheap labour, and eventually closed in 1943. Island division In September 1894, heavy seas drove aground the barque Cambus Wallace at a narrow isthmus roughly halfway down the island's length. Salvage activity (including the detonation of a cargo of explosives) weakened the sand dunes along the spit such that by the spring of 1896, storms and tides had
