Actually, our tickets are valid in most of Australia - don't ask me why I recently researched this :) There they do it by state, and up till recently you did not need a ticket at all for what we would call a skiboat.
Our recreational tickets are seen as some of the toughest in the world - but remember it does not qulify you for a 9m plus boat. And of course the more commercial tickets (like Yachtmaster Offshore etc) are a different ballpark altogether, and there you need to do it through one of the internationally recognized agencies.
