Not content with land and sea activities? Take to the air with a futuristic water-propelled jetpack from Jetpack Adventures that shoots you up as high as 30 feet (or 8.5 metres) into the air. As your sci-fi moment takes place over water, crash landing is safe (and refreshing). With locations including Sydney and the Gold Coast, Jetpack Adventures has now added Airlie Beach to its adrenalin-packed sites. This one’s for older teenagers aged 16-plus, and adventurous mums and dads.
