Adelaide has pandas, Sydney had the Olympics in 2000, Melbourne had the presidents Cup a few months ago (I was there) and there are numerouse 'Queens' around OZ. Queen Liz visits sometimes, and I have already been to Bucking-huge Palace to see her, Chuck and Di in their back yard (20 years ago!). So, no need for an imminent visit.
That said, I might be visiting in 2013 April. The 'reverse' Thames run is on in that ton called London and I have a friend who has conned me into doing it. I hope there is some golf involved before my feet give up!
