Another approach would be to split the distance and set up housekeeping in a "neutral third country" somewhere. Not that there aren't other problems with that, but it's at least a compromise.

A little more seriously, though, do consider all the modern technological marvels available these days that make living apart from family much more convenient and easy to deal with than ever before. There are very low cost "telephone" services, like Skype and other VOIP systems, video streaming on the Internet and air fares that, while not exactly cheap, are certainly much less expensive than those of 10 or 15 years ago.

When I first came over to Europe from the US, e-mail seemed like a huge breakthrough in terms of staying in touch with friends and (some) family. No more waiting weeks for a handwritten letter to get there! Now, I've got a phone number in the US so people there can call me (or leave me a message if I'm not online when they call). I handle my father's finances via Internet, and a quick stop into his bank when I'm over for a visit.

And why couldn't your family members come visit you (wherever you decide to settle)? Maybe they'd enjoy having family to visit in Oz (or your BF's family might like the excuse to come over to Canada once or twice a year). Being physically far away doesn't mean you lose emotional closeness with family members - and remember there are plenty of newlyweds who would love to get away from all the family all the time!
