In commonwealth service the rear body was slightly narrower (to fit into aircraft if I recall correctly). Don't have my reference handy at the moment - but I'll confirm and update later.
Don't know whether the Aussies used them but I do know that many of the vehicles that were in Canadian service in Europe during the war ended up in post war service in Indonesia with the Dutch so if your heart is set on the far east - maybe a good second choice option?
