We have them as often as you guys do, every four yeras, but it's the year before yours is. And I just checked wiki to see if we have a vote of no confidence, how awful that I don't even know, but it's not like that's something that the people get to decide. However, if you're up for some reading on Australian political history, I've always found the Gough Whitlam/Malcolm Fraser/John Kerr incident pretty interesting (though I've only ever been recounted it by my father, who remembers vividly everyone's reactions to it).

It wasn't the link, but it seemed to time out halfway through and the page didn't finish loading! Very frustrating :(
