Thorneside, located in the north of Redland City is bounded by Moreton Bay to the north and west, Ruth Street, the suburb of Birkdale, Thorne Road and Henry Street in the east, and the railway line, Quarry Road and Rickertt Road in the south. Thorneside has a land area of 257 hectares or approximately 3km2. Thorneside is named after the railway station, which was named after William Thorne, an early landholder.
Settlement of the area dates from the mid 1800s, with land used mainly for farming. Population was minimal until the 1880s when the railway came through. In the early 1900s the land was subdivided and sold as primarily residential developments. Significant development did not occur until the late 1960s. Rapid growth took place during the 1970s and 1980s, with population growth slowing during the early 1990s. The population increased marginally between 1996 and 2011, a result of fewer new dwellings being added to the area and generally a decline in the average number of persons living in each dwelling. Today, Thorneside is primarily a residential suburb with a small pocket of industrial land.
Major features of the area include William Taylor Sportsground, Aquatic Paradise Park West, Beth Boyd Park, Williams Weber Reserve, Frank Street Bushland Refuge, Jack & Edna Finney Reserve, Thorneside Village Shopping Centre, Thorneside Community Hall and access to Moreton Bay.
