My Husband and I are going to Australia in a couple of weeks and can't decide on an itinerary. We are flying into Sydney then directly to Cairns. We are going to dive the reef for 2 or 3 days then have the rest of our quick 9 day trip to discover something else however we must make our way back to Sydney to leave. We have thought about driving from Cairns to Brisbane stopping at Whitsundays for a day then flying back down to Sydney but I don't think we will have enough time. Any suggestions?
