Mining and Pastoral Region
The Mining and Pastoral Region was a multi-member electoral region of the Western Australian Legislative Council, located in the northern and eastern regions of the state. It was created by the Acts Amendment Act 1987, and became effective on 22 May 1989 with five members who had been elected at the 1989 state election three months earlier. At the 2008 election, it was increased to six members.
The region, along with all other Western Australian Electoral Regions, was abolished in time with the 2025 state election, following legislation passed in November 2021 to create a single, state-wide constituency of 37 members.
