Suppose we need a bus licence too, to taxi after landing on regular runways. Onya Tasmania.
You notice of course that cars are kept off taxiways for that very reason (can't have only half the vehicles knowing the rules
). If you were taxiing on public roads, with public traffic and public road rules - then yes, a bus license would make sense.
It makes sense to me that while operating on the water, a pilot should know how to avoid collision with other water users, how to interpret channel markers and the like.
The Limited Coxswain certificate was a qualification only recognised in Tasmania, and it ceased to be issued on the 31 December 2002. The Limited Coxswain certificate has been replaced by the
Coxswain (Restricted) certificate.
... having said that, requiring a certificate which has a six month sea service (at a minimum) requirement to achieve is pretty onerous.
