significant infrastructure at this time. On 11 November 1879, under the Divisional Boards Act 1879, the Tingalpa Division was created to govern the area to the east of metropolitan Brisbane. The area around Cleveland split away to form the Cleveland Division on 30 May 1885. Under the Local Authorities Act 1902, both became Shires on 31 March 1903. The Tingalpa council met at Mount Cotton. On 1 October 1925, a sizeable portion of the Shire of Tingalpa (suburbs west of Tingalpa Creek, including Upper Mount Gravatt and Rochedale) became part of the new City of Brisbane along with 20 other local governments. On 9 December 1948, as part of a major reorganisation of local government in South East Queensland, an Order in Council renamed the Shire of Cleveland to be Shire of Redland and amalgamated part of Shire of Tingalpa into it (the other part of Tingalpa amalgamated to form the Shire of Albert). The twentieth century saw significant population growth in the Redlands, preceded by the construction of the Cleveland railway line. Peel Island became a leper colony, while North Stradbroke Island became a hub for sand mining, and is also associated with the Indigenous rights movement as the home of poet Oodgeroo Noonuccal and academic Aileen Moreton-Robinson. On 15 March 2008, Redlands was granted city status. In June 2018, the Redland City Council approved a marketing campaign to brand the city as "Redlands Coast" with the tagline "naturally wonderful". The campaign seeks to attract tourists to the city's of coastline (due to a number of islands which form part of the city). Geography Although most of the population resides on the main urban conglomeration based around the centres of Capalaba, Cleveland and Victoria Point, over 6,000 people live on islands in Moreton Bay that are part of the city. These are North Stradbroke, Coochiemudlo and the Southern Moreton Bay Islands of Karragarra, Lamb, Russell and Macleay. Tingalpa Creek rises on Mount Cotton, forming Leslie Harrison Dam, and marking the majority of the area's western boundary. Environment Redland City has many immediately recognisable animals and plants such as koalas, migratory shorebirds, flying foxes and scribbly gum forests. It is also home to over 1,700 other recorded native species, many of which are under threat from population growth and its associated effects such as habitat clearing and fragmentation, road construction, pollution and expanding development. The council area is also home
