Buayanyup River

The headwaters of the river rise in the Whicher Range and flow north crossing the Bussell Highway near Vasse before discharging into Geographe Bay near Abbey about 8 kilometres (5 mi) west of Busselton.

[3] The river has three main tributaries of Dawson Gulley, Ironstone Gully and the other is not named.

[5] The river flows through agricultural land that is predominantly used for raising beef and dairy cattle and to a lesser degree plantation timber and viticulture.

The area has been settled since 1834 when the Bussell family established a cattle station along the Vasse River.

The name of the river was first recorded by a surveyor in 1839 and is Aboriginal in origin but its meaning is unknown.
