Keoki's sire (Buka) is an Aussie import. He is good-sized, though I haven't wicketed him. But I know he is one of our biggest dog, probably 17.5-18" tall, but very well proportioned.
As Pat said, it doens't matter where they are from as to their size. I've seen some really small Aussie dogs, just as some American dogs can be really big and some can be really little.
