I'm what you would call a Sydney Anglican - characterised by a largely conservative worldview. The only party I can see that is worth voting for, ironically, is The Greens.
Check out the Sex Party. Despite the stupid name, they're actually a civil liberties party - equality for all, privacy, net neutrality, that sort of thing. At least at the last federal election they were.
Meh, the greens are a gimmick party. Even the democrats were a gimmick party - their slogan was for a long time not even about their own party ('keep the bastards honest'). I'd much rather the Sex Party get the last senate seat than the DLP (who nabbed it in Vic last time around).
Pretty much any party that hasn't had a serious go in power is a gimmick party, simply due to lack of experience.
You're just redefining "gimmick" to suit your argument. I don't consider minor and microparties to be gimmicks because they don't get many votes.
I consider them gimmicks if they use a gimmicky tactic to garner votes.
I consider the Sex Party to be a gimmick. Because teehee, Sex Party, get it?
We are talking about the Parliament of the Commonwealth of Australia, not the sort of suburban football club or undergraduate student union for which such puerile names are appropriate.
And it really irks me that gimmick parties deprive other micros of the tiny amount of attention they get.
Honestly, I miss the Australian Democrats. They were boring, sensible centrists. And it was great.
