DH, DS (2) and I are going to Cairns for a week at the start of July. Most of the time I will be in a conference so I am looking for good things that DH and DS can do during the day. What are the 'must-sees' in Cairns? We already have accommodation but looking for things to do that I will regret if we miss them We are on a budget (poor students - ha!) but if something is really worth the expense then I am happy to outlay some money.
Please please advise!!
Kris
