I am going to Australia for a month in May/June and my fiancee and I will be renting a campervan in Brisbane and driving to Cairns. We have 3 weeks allocated for the drive. If anyone has suggestions on places I shouldn't miss or great camping grounds along the way I would really appreciate them. We love the outdoors and snorkeling so are hoping we can stay close to the coast the entire journey.

Thanks for your suggestions!
