Australia more like the States than Canada? Surely you jest.
Perhaps the audio/visual aspect, although Australia uses the same freeway signs/font (green background/white lettering) as the USA.
I have lived in both countries for extended periods (4 months in Vancouver, 2 months in Toronto; 6 months in Sydney).
The lifestyle in Australia was much closer to what I have grown up to in the States. In Canada, my clients were out the door at 5-6 pm everyday. In Australia, we'd pull all-nighters together.
Australians and Americans share a national pride of home ownership; I don't get that as strongly from Canadians.
Australians don't find the fact that Americans can have guns as wrong/odd as Canadians. In fact, it's typically the Australians who are next in line to support the big, bad America in the wars that we start. (I don't want this to derail the thread for the OP; I'm just stating an observation and not starting a political discussion.)
Sydney looks like San Francisco except in the Southern Hemisphere with Los Angeles weather.
Brisbane looks like San Diego/Honolulu, with similar geography and architecture.
Obviously, these are my opinions and observations. But based on my experiences living in both places, as one who was born and raised in the US, Australia felt closer to home than Canada, even though it's 4x the distance!
