The headwaters of the river rise in the Whicher Range and flows north crossing the Bussell Highway near Vasse before discharging into Geographe Bay near Abbey about 8 kilometres (5 mi) west of Busselton. The river has three main tributaries of Dawson Gulley, Ironstone Gully and the other is not named. In total the river has a stream length of over 100 kilometres (62 mi).
Flowing 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. More farming families followed and now over 50% of the catchment is used for cattle farming.
