CC, some of my clients bring their wives and families with them to Cairns.
While the men are out hunting the family does tours of the Great Barrier Reef and goes shopping etc.
There are plenty of places to see and things to do in Cairns as it is the tourist capital of North Queensland.
When we return to Cairns after the hunt we often have a big get-together of the hunters and their families, and of course the guide, and dine on fresh seafood, beer wine or whatever else.

Hope you really enjoy your new double 470.
