Until the 1950 elections, it covered Perth's central business district and nearby environs, but moved at that point to the western and northern suburbs while still extending to include Perth itself. In 1963–1964, electoral changes to the Legislative Council, which abolished the 10 three-member seats and created 15 two-member seats in their place, resulted in the seat shrinking into the wealthy western suburbs region. Thereafter, it was a safe seat for the Liberal Party. In 1989, the province was abolished by the Acts Amendment (Electoral Reform) Act 1987, and with two others became part of the North Metropolitan Region under the new proportional voting system.
