Here's Goldfinger from Whitehaven Beach.

The highlight of the day was the sea turtles. We saw 6 huge ones in our 15km journey, each about 5-6 feet long. A 7th was only about 3 feet long. The first one we saw was right where the boat is in this picture. He was about 10 feet away from the boat when we were weighing anchor. They each followed the same pattern: They would surface, see the boat and then quickly make a deep dive. They were a surprising lime green color.

I thought the first one was a big clump of seaweed until he opened his eye. Dude! After that, we were looking for seaweed clumps all day.
