Carbrook, an eastern outer rural/residential suburb of Logan City, is 30 km south-east of central Brisbane.

First settled by Europeans in 1868 it was occupied mostly by German families who named the locality Gramzow. The change of name to Carbrook occurred in 1916, during World War I, but the German influence is maintained with the heritage-listed Lutheran cemetery at the corner of Mount Cotton and Wuduru Roads and by Gramzow Road north of the cemetery.

A Lutheran church was opened in 1876, a year before the state primary school. Local farmers grew sugar cane, arrowroot and bananas. Dairying became the main farm industry when the Kingston butter factory was opened. Most farm produce, as well as timber from farm lands as they were cleared, depended on the Logan River for transport; a wharf and ferry were installed at the end of Mount Cotton Road at what is now Skinners Park.

Carbrook was a farming community with scarcely over 120 people until the early 1970s. Expanding suburbia made Carbrook a conveniently accessible location for a golf course in 1977, and rural/residential subdivisions absorbed the former farmlands. Further east a caravan park and water-ski lake were opened, and wetland conservation parks were reserved. Kimberley College (2000) and Calvery Christian College (2002) are near the state primary school. (The original 1877 school building is listed on the Queensland heritage register, and the replacement building was opened in 1989.)

For census purposes Carbrook has been included with Cornubia since 1986, Cornubia consisting mainly of conventional residential subdivisions. The census populations of Carbrook have been:
