Nice to see my political equivalents in Aus are fighting this.
Labor have been hit and miss lately. With much of the crazy shit the LNP introduced in the budget, Greens and Labor have been voting against them, but sometimes (as with the carbon pricing scheme) it's not enough as the LNP hold quite a few seats and only need a few independents/bogan party members to vote with them.
Unfortunately Labor voted for these terror laws, which effectively means they're passed. The Greens are the only ones with some power still fighting things like that. They're the only party with seats in the senate whose members can spell 'internet'.
Here's a few choice quotes that I feel reflect the position of each party fairly well:
DAVID LEYONHJELM, LIBERAL DEMOCRATIC PARTY SENATOR: The case for the bill has not been made.
GLENN LAZARUS (Bogan Party): The internet poses one of the greatest threats to our existence.
SCOTT LUDLAM, GREENS SENATOR: Obstinate silence. Misinformation. Bluster and procedural abuse. This is how our freedoms are being deleted, line by line, by those whose recklessness is only exceeded by their mediocrity.
NICK XENOPHON, INDEPENDENT SENATOR: Some parts of the legislation have gone too far without adequate safeguards.
TONY ABBOTT: Regrettably, for some time to come, the delicate balance between freedom and security may have to shift.
