Preferential voting is awesome and way more democratic than one-man-one-vote.
"Then your vote for the Greens gets counted as a vote for Labor, whether you wanted Labor in power or not"
I have no idea how you came to this conclusion. The ballot paper has a space for each candidate and your vote for all of them in the order of YOUR preference. If there are multiple candidates in the election that you absolutely despise then there is a chance your vote will help get one of them elected, but never the one you placed last. And compared to how "splitting the vote" affects the outcome of winner-takes-all voting you actually get a choice as to which less-preferred candidate you end up putting in power.
Australia's system is very good, all it needs to strengthen it is a "none of them" option which, if it comes in over 50%, would require a new election to be held with all new candidates.
