Every day, I probably spend three or four hours in the water on the Great Barrier Reef. I work as a reef guide-slash-marine biologist on Lady Elliot Island, so I do all the snorkelling tours and reef walking tours. I’ve been really lucky while I’ve been working out there: I’ve seen a lot of rare stuff, probably because I spend so much time out there. I’ve spotted ornate eagle rays and tiger sharks; I snorkelled with a great white two weeks ago.
