I was in the water with my wife and two daughters - aged four and ten - and this humpback calf was most interested in the girls. The youngest would retreat to the safety of her mother's back when the whale came too close for comfort, but this seemed to only intrigue the whale more. The young whale would swim circles around us and then dive down to its' mother and her male escort 20 metres below before coming back up to repeat the inspection.
