Hey mate, I did the Whitsundays on a 300x during my trip around Australia.

I learnt a lot, and the main thing is the islands are not generally PWC friendly. Long Island is the exception. Hamilton and Day Dream are highly over-rated (and you can't just pull up on them).

Have read and ask any questions.

Cheers, Mal
