Balyang Sanctuary is a public park in the suburb of Newtown, Geelong. Situated on the banks of the Barwon River, it is 20 acres in size and consists of open park lands, lakes, and wetlands. It was opened in 1973. Attempts were made remove introduced European carp from the lake in the early 2000s but were unsuccessful, however the extended drought over the summer of 2007 resulted in the lake drying up. Early 2007 saw the Sanctuary upgraded, with the bluestone edging of the lake removed, and the lake rebuilt to closer resemble a natural wetland.
