help!!! with foreign exchange

I'm moving overseas to work in Canada and several bank institutions that I've checked changed currency through travelex etc at ridiculous rates. Current spot market rate is $1Aussie for $0.98 Canadian (approx). Travelex sell rate is bloody 91 cents. Huge loss! Does anyone know how I can exchange a substantial amount closer to the actual market rate! Any suggestions would be very helpful. Thanks
