I love Australia. Half my dad's family live in Brisbane (my aunt and her husband moved there on one of the infamous '£10 flights' back in the 70s, and they never left), and I also worked in Melbourne for a month while I was at university and have travelled a bit (Canberra, Sydney, Fraser Island). I'd love to go to Perth one day though, and I'd like to see Ayre's Rock one day, oh, and the Great Barrier Reef.
Also, the weather is better (although it was hard to believe when it rained in Melbourne for the entire month I was there :P), although perhaps a little too hot for me in summer (I've only ever been in winter), so although I love to visit, I'm not sure I could live there with that heat (especially with all the spiders, snakes etc!). I think I'd prefer to live in New Zealand where it's a little cooler, and where everything is closer together. Australia is so spread out that you have to fly to get anywhere. Plus I think the scenery is more spectacular in NZ. Still, I do love Australia too, and I wouldn't rule out living and working there for a year sometime, but preferably in the south where it's cooler, like Melbourne or Adelaide.
Every Australian I've ever met has been lovely. I also love the accent (especially on Hugh Jackman ;)).
