We recently spent some time in Australia, and absolutely LOVED Melbourne. It`s the only other city I`ve ever visited that I`ve seriously considered moving to. When I looked at the local real estate listings (as I do everywhere I go) it seemed that prices were very high compared to rents. It seems you might need to find a specific niche where you can make profits. Some on this board have had good luck with student housing, rent-to-own, etc.
I was also very interested with all the condominiumized office and retail spaces. There might be some sort of opportunity there, although I`m not sure precisely what it would be.
