The Greens are firmly TWAW and they hold the balance of power in the Senate. I don’t trust the Teals to not Be Kind, either.
That being said, I spoke to Sen Michalia Cash last year and she said that Labor will never introduce a bill on the subject (I assume because A) they will never admit that they were wrong in the first place and B) they have to fight the Greens for every vote they receive so don’t want to bring attention to the subject). The Liberals (well, last year when they had more seats) were keeping an eye on the subject but waited for Giggle v Tickle at the High Court to be resolved.
Just about every member of the Parliament last year (note to non Australians, we had an election a couple of months ago and there are a lot of new members) was lobbied hard in the subject. People walked the corridors of the place and knocked on every door with hand outs. No one in the last Parliament can claim ignorance of the issue.
