Looks like a slight win on the Exchange Rate, and a slight win on food prices.
www.livingin-canada.com/food-prices-canada.htmlYou can actually survive quite well OS with an Aus Bank Account. Online banking, Visa Card, etc. I found that if you withdraw the Maximum Limit through an OS ATM, it goes a long way, with only minimal transaction fees. Visa Cards aren't that bad with International Fees either.
Failing that, you just do an International Money Transfer for about $30, into a Canadian Account, if you have one. Have you made an inquiry with your bank?
