I thought you'd be thinking of MMP - that nearest loser sounds interesting! It does seem to be the road to better representation.

I'm all for change - I think it'd need to be accompanied with plenty of education in the form of AEC ads on tv and online. Not so much the 'how to vote' but more the 'how our system works'. Plenty of people I talk to have no idea about IRV, and consider voting for anything other than libs or Labor "throwing your vote" - which it can totally not be if people are aware of how it works.
