Not sure you'd find anything on the German market either and if you did it would be heavily censored (no swastikas allowed for example). Also, most Germans would probably rather play as the allies fighting against Nazism.
Zip is right about the Aussies contribution in both world wars and also their major contribution in Vietnam which also never appears in games based on that conflict.
Flight sims seem to be the only games with the option to play as other country's forces - IL2 allows you to fly in German, British, American, Finnish, Polish, Japanese as well as the Aussie and Kiwi planes.
