Oh and there was the time I saw a submarine

I think this is the end of Australia.

I had completely forgotten about this. We sailed out of Cairns to the Great Barrier Reef, and suddenly this submarine appeared next to our boat. After a few minutes it submerged again, but I'm not sure anyone ever explained to us what it was doing there. Looking at the picture now, I realize that it actually wasn't that big and was possibly some kind of scientific vessel, though it looked enormous at the time.

A suitably strange incident to wrap up pictures from a strange and wonderful place.
