The term affectionately used by residents of the city of Perth in Western Australia, to refer to the area in the south-west of the state underneath Perth.

In general it can refer to the whole area south of Perth and west of Albany, but usually only means the Cape Naturaliste-Cape Leeuwin region, in particular the towns of Busselton, Dunsborough, and Margaret River.
