Shute harbour is a commercial harbour with the most fantatsic views reminiscent of the Caribbean (BVI?). There is a logistics terminal and not much else other than a ferry point for island trips (e.g. Palm Bay) or boat pick up (Sun Sails).
There are nature walks and a viewing point above the harbour. I recommend a stop here just to tak in the atmosphere. It is beautiful although on a windy day you get the full brunt of the wind hitting Airlie.
