Ah Melbourne.... it's a pretty happening place. If you can put up with it being on fire two months out of the year, and the fact that you need two days if you want to travel there, then everything else about it is wonderful.
So far my only sandbelt experience was a round at Commonwealth and a couple of trips to Huntingdale and Victoria for the Aussie Masters and Open, respectively. I've also played another Aussie Open venue which was the championship course at Moonah Links, which was kind of a misnomer and an okay course but it didn't really feel like it was worthy of hosting the most significant tournament in the land. All the time I spent in Melbourne (enough to become a dual citizen) wasn't enough to get me on the Royal.... both times I had letters that were never answered. I also had a chance to play Metro, but the green fee was too high for a soon-to-be-married 25 year-old with no job.
It's become a bit less liveable I think since I was last there.... mind you, it's still pretty liveable (it always seems to be on top or near the top of those silly lists) but I think the weakness of our dollar and the strength of their economy relative to everyone else's has made it a very expensive place to live, and I'm really not a fan of the new government.
If you can, get to the Melbourne Cricket Ground and watch an AFL match. Yes, they are trying to take the violence out of it, like any other sport these days, but it is still very much worth watching. They play at a few venues, but the MCG is the spiritual home of the sport, and if you can get there on a day when two of Essendon, Richmond, Carlton, Hawthorn, or Collingwood are playing each other and you might get 80-90 thousand spectators, usually split 50/50 in support. Some of the diehards, especially those who follow Collingwood, must be seen and heard to be believed. I have to say, I really got into it when I was there.
Melbourne's a pretty awesome place.... it's just too damn hot and too damn far away. But it can steal your heart if you aren't careful... I ended up marrying a Melbourne girl and wouldn't have it any other way.
