Bennett Brook is a stream that runs from Whiteman Park to the Swan River in Western Australia.

Approximately half of the catchment area is covered by Whiteman Park and the Gnangara Pine Plantation.

The rest of the catchment is urbanised, covering the suburbs of Ballajura, Beechboro, Bennett Springs, Kiara, Lockridge, Malaga, Morley and Noranda.

[1][2] By the 1960s, Lew Whiteman, the owner of much of the land that makes up Whiteman Park today, built a dam across Bennett Brook and deepened a natural pool along the brook to form the Mussel Pool, named due to the naturally occurring freshwater mussels.

The first fish ladder in Australia, it was designed by a Murdoch University zoologist and built by a team of people on the Work for the Dole program.
