601, that was for the OP,
Due to Australia's costs offshore might be better options - and the foreign licence is the required licence to have, even if granted from an AU one.
If only operating in Australia a VH rego maybe ok, but if you are operating in several countries. Better money is often offshore.
This is highlighted by my costs of buying Qantas tickets in Australia vs Singapore, that seems to have no comment reply to my original post/comment - funny that.
