Planning a trip from Mackay north to Airly or Shute. Have done the standard Whitsundays numerous times. Most parties seem to leave from Blacks Beach and head to Brampton/Carlisle, but St Bees and Keswick are also national park and look interesting. Has anyone been out to either of those two islands? The crossing from Blacks Beach is similar length whether you go Keswick/St Bees or Brampton/Carlisle, although the latter is a bit more northerly.
