What a fit child you must have been! How lucky! I enjoyed swimming, but was too heavy (lower body) for gymnastics, and couldn't even climb a rope. Philip Island is the one where we went to see the penguins come up from the sea - a bit of a circus. I also saw their burrows on Kangaroo Island and heard their strange donkey noises. Cute!
One day on North Stradbroke, I decided I was going to try to swim out to the dolphins ... they swam away of course, and I got caught in a bit of a rip current, but managed to swim across it and scramble onto some rocks, and when I got back to shore, they assured me that I was being dragged into a "shark nest"!
