CPA doesn't really do electoral entryism (and is probably the most hexbear approved Australian communist party). Socialist Alliance (ex-trots) do earnestly run for government sometimes, but are part of a gaggle of minor parties whose preferential votes disappear often, though they've gotten to city council.

This is just based on my local experience of being around them and volunteering, I haven't gotten into a discussion about their paths to power. There's a tacit acknowledgement that a dozen part time nerds is probably not changing much so while they occasionally scoff at each other, there's also a lot of cross-pollination and protests etc organised between them (and a few others).

Electorally, both of their voters generally wind up preferencing the greens, which are a big tent left party with the occasional embarrassing Malthusian, or Labor which is a blairite shit pit with the occasional left radical member.

Recently, the Australian electoral rules changed which increased the requirements for a party to be on the ballot, but I actually don't see that changing much in terms of actual electoral results.

I think realistically Australia is going to be one of the last countries with a population over 10 million to go red, despite the efforts of my comrades. Wealthy, high minimum wages, white settler nationalism very strong, most rabid antiCPC reflex etc.

I did meet a Cuban delegation through the CPA and Socialist Alliance, which was nice.
