Cairns: Coral Coast Triathlon

Just wondering if anyone has done this Triathlon before, I have signed up for it for the 2nd June 2013, (my first ever Olympic length) and wanted to get an idea of what the different legs were like.

Is there much current in the swim, what is the sighting like, did you where a wetsuit for the event? Is the bike leg flat or hilly etc.

Would be grateful for any handy hints.
