Following reddragdiva's heads-up, I trekked down to the Australian Embassy in Rome to see about voting in the upcoming election and what needs to be done. I found that the embassy was closed until Monday (i.e., after enrolments close), as they're relocating it. Coincidence, or conspiracy to disenfranchise non-Tory-voting pinko backpacker types in Italy?
Anyway, I've checked my enrolment online, and it's valid. With any luck, I should be able to vote in London just by rocking up on the day with my passport. (There's nothing there saying one can't, as far as I can see.)
What sort of buzz are you picking up from afar? I will say that there's definitely a different tone to the campaign than the last one. In spite of the ebullience of some anti-government pundits, it's still waaay too early to tell whether you turn out to have escaped another few years of Liberal stupidity...
