I read the article t'other day. Interesting comments below the line from Aussies.

It's up to the Aussies if they want to become a republic or not. You've been a country for about a 100 years IIRC, so you don't need anyones permission how you choose to be governed. As someone who doesn't really favour the Royal Family, I will say this though. Be careful what you wish for and if it aint broke, why try and fix it? The Aussies have done more than OK with the present form of governance. Remember that a politician would be President, and that's never a good thing IMO.

CA congrats on going in purdah. When did this happen and how much did it cost?
