So, it's obviously a relative thing. Your vote matters a shit tonne more in IRV than in FPTP, of course.

But it's also a lot less than proportional systems. At the last federal election, over 12% of Australians wanted a Greens representative. Less than 3% actually got one.

A combined 9% wanted One Nation and United Australia Party. They got 0. Labor got 51% of seats, from less than 33% of votes. The LNP is actually the most fairly-represented party, getting 39% of seats from 36% of votes.

My preference is a proportional system. Probably MMP, to keep local representation, as well as to remove the need for party lists. Rather than the proportional seats being done in party order, I'd do them in "nearest loser" order based on their local races. But that's a very niche aspect. The important thing is that it be some form of proportional representation.

A counter-argument could be that our Senate uses STV, which is quasi-proportional. Which is certainly a good thing, and far better than if we didn't have it. But it's still only a rough approximation of proportionality. Labor and the LNP each won 39% of seats, from their 30% and 34% of votes. That equates to 3 or 4 seats too many for Labor, and 1 or 2 too many for the LNP.

But even if it did work perfectly, the fact is that all the attention and most of the power is in the House of Representatives. It can be very disheartening and discouraging for someone engaged politically who doesn't support Labor or the LNP to know that the chances that the candidate they give their vote to will probably not actually get in, and that's not good for civic engagement.
