The thing with exhausting your vote is that what you're doing is effectively ranking all other parties equal (to be more exact, you're lowering the quota and thus making it a bit easier for them to be elected on other people's votes). That's fine if you genuinely don't care which of them (if any) gets elected, not so much if you think the slightly-oddball-but-harmless micro party is a less awful prospect than the racists or the shooters (or, if you're coming from a right-wing perspective, your relative rankings of the Greens and the assorted leftover fragments of communism).
I've come across a few sites that have looked more closely at the various micro-parties and independents running in Victoria (one good one is here
). Haven't come across anything similar for NSW yet but there's probably one out there (and of course most of the parties are common between the two states).
