TBH after having slept it over I'm more optimistic about this. Sure, the conservatives won with an absolute majority, but they were getting to do whatever they wanted in regards to neocon economic reforms anyway, voting together with the other major party.
On the other hand, many minor parties went up quite a bit, including the one I voted for. In fact, they were likely the ones that went up the most, almost doubling their votes from the 2008 elections.
I hope they get to keep it, too. They lost votes over time because the labor party (one of the two major parties) kept making propaganda during campaigns advising people to do "useful voting" (meaning vote for them instead of other left-oriented parties because this way there'd be less of a chance for the conservatives to win). This quickly turned them into "useless votes", because they're not that different from the consies, deep down. All in all this policy was part of a greater campaign of theirs to push for a two-party system (which in a way is already there. Representation is nowhere near proportional to the obtained votes with the d'Hont law), and at least this part of it blew in their face.
Shame about gay marriage, though. The conservatives promised they'd remove it if they went into power, and they might well follow this one particular promise through.
