He was not "playing". He was making a documentary on the Great Barrier Reef. In fact, he was filming something for his daughter when he was killed. And that's why you teach them how to look for snakes. I have been tracking these hills since I was 5, and I've never been bit by a snake I didn't pick up. I know how to handle animals though, and knew to wear gloves and boots. Walking around in sandals or flip flops is stupid.
