After travelling the world pretty extensivly, i find that canada is definately the most similar place to australia i have ever been, having lived in vancouver and calgary, and now living in london uk for over a year, i think we are hardly like england at all. There are parts of sydney and melbourne i have to look twice at to make sure i havnt fallen asleep and found myself back in the great white north.

The thing that definately sets Australia appart from london is most definately the food, i have always heard that england has a bed reputation for food, and it has.
Sydney kills london in the eats department, london has a lot of nice high end places to eat, then so does sydney, then so does any of the worlds big cities. But i know that within 3 minute walk in sydney you can stumble on about 5 different nationalities cuisine, all tasting great and affordable, but in london unless your in the city, good luck. Its a pub, a fish and chip shop or a curry. A lot of the times nothing at all.
