Brockman River is a river in wheatbelt region of Western Australia that rises north of Bindoon Hill and then flows in a southerly direction. The river crosses the Great Northern Highway near the Bindoon-Moora Road turn off then travels parallel with the highway as it continues southward. Passing the town of Bindoon and through Lake Needoonga and Lake Chittering the river crosses the highway as it veers eastward. The river then passes Lower Chittering and finally discharges into the Avon River, of which it is a tributary, near Jumperkine Hill just north of Walyung National Park.
The Brockman has the largest catchment in the Lower Avon and Upper Swan River catchments. The natural resource base of the river is deteriorating as a result of clearing of natural vegetation which in turn has led to erosion and salinity.
The river has many smaller tributaries including; Wootra Brook, Spice Brook and Marbling Brook.
The first European to discover the river was the surveyor Francis Thomas Gregory who named he river in 1853. The river is named after William Locke Brockman who was a pastoralist in the region with large land holdings and a Member of the Western Australian Legislative Council. [3]
