The coffee issue Australians have with coffee from other countries is usually the strength of the coffee, we drink our coffee strong. Most Australians find that American coffee is too weak and while you say it doesn't matter if the quality is a bit different it does matter if you are used to strong coffee to get weak coffee. For example I usually ask for double or triple shots when on cruises or in the US. Not all countries make weak coffee, however, the US and cruises seem to.
