Why is Australia’s electoral system unconstitutional?

If the Preferential Voting system appears to be perfectly designed to keep the two major parties in power, it actually is. The preferential voting system was introduced by the Nationalist Party in 1918 as a ploy for them to remain in power. It is not mandated by the constitution to use this or any other system of voting, and it was unnecessary when introduced and now it is the biggest hurdle towards progress in Australia.

The origins of the preferential voting system are completely omitted from educational curriculum in Australian schools and universities, and have been for generations. Preferential voting is essentially taught as "the word of god" of sorts. Furthermore, materials published regularly about elections use language that can only be described as gaslighting.

Compulsory preferential voting in single-member electorates violates fundamental democratic principles under the Australian Constitution.
