Mark McGowan swept back into office in WA in a landslide, and he’s now about to make it much harder for the conservative side of politics in the state to maintain its traditional control of the upper house of Parliament.

The WA Nationals are up in arms over a proposal to do away with weighted electorates in the Legislative Council, which has blocked previous attempts at electoral reform.

Under the current system, there is a wide discrepancy in the worth of a vote in the Legislative Council, against which WA Labor has been campaigning for decades in favour of one vote, one value.
