For an adrenalin buzz first up, try tandem skydiving or kite surfing. Scuba-lovers will appreciate the ex HMAS Brisbane dive site at Mooloolaba but if observing the marine world while staying dry is more appealing, Mooloolaba's Underwater World is very popular with families.
Kids also love the action and novelty of Australia Zoo. The Bellingham Maze at Tanawah and Ettamogah Pub on the Bruce Highway are quirky sites and a drive through the hinterland reveals gorgeous scenery. Be sure to book a flight to Maroochydore well in advance if traveling in school vacations.
