Hello - my husband and I and our 15 year old daughter are visiting our 22 year old daughter who is living in the Gold Coast for a year. We will spend 2 days in the Gold Coast area. We then have four days to go and do something north of Gold Coast. We could rent a car and just drive up the cost towards Hervey Bay or Fraser Island. Not too sure if there is enough to see and do for four days. We love to swim and snorkel. From my research there are no good places to snorkel unless you go up towards Cairns. We would have to fly if we went to Cairns which is an extra $1,000.00. But if we have come this far (from Vancouver, Canada) then maybe we should go and see the Great Barrier Reef. We will then hop on a plane and head to New Zealand for 25 days. Any tips on what we could do or where we could go in this general area (within 6 hour drive of Brisbane) would be helpful. Or is it worth it to fly into Cairns. Thanks!
