I took my partner who is British back to Australia for a few years and we only just came back. Nothing to do with Oz she just couldn't secure full time work as a teacher where we were living and got a little home sick. Dee Why is where we were living btw and we were renting a nice little 2 bed flat 10 mins walk from the beach for £1200 a month. Like all major cities around the world Sydney is expensive so you would want to earn $80,000 or more for a comfortable lifestyle. Public transport sucks in Sydney though.
