huh? do you mean popular vote? if so - yes and no - we have a pass-the-post system where we only vote for our MP (member of parliament) - the party that wins the most seats in the house, the defacto party leader becomes the prime minister. but our system is also flawed as well.
No, I meant proportional representation.
yes we do and that is one of the problems we have - we have huge cities like where i live where millions of people live who have areas that thousands of people which share the same weight as rural areas with very small populations. so yes, from my perspective 1 person 1 vote is da bomb!
