Vote for independents, even if you're sure they'll lose. Preferential voting is a beautiful system which benefits you in ways you might not realise.
It forces the winning party to consider emulating the top independents. It also encourages the independents to try again.
My top choice is always whoever has the best environmental protection policies, animal welfare protections, and wants to address climate change.
This normally means I vote: Independents > Greens > Labour > Liberal > Nationals
