Hey Peter,

Loved your JAWS piece — made me smile. At Boatshed, “You’re gonna need a bigger boat” is on our shirts, our walls, everywhere. Ironic, of course. Thought you’d appreciate the overlap. Nice work!

Thanks for covering this, Peter.

I've dived with sharks many times, including diving at places where sharks are fed. I'm opposed to feeding the larger, more aggressive sharks, but I've watched reef sharks and grey nurses zoom in on fish-heads and that's no different from what they do when fishing-boats dump their by-catch. You can learn a lot from watching it up close.

Maybe Australians are used to lethal wildlife, but nationally we've had 186 reported incidents of shark attacks since 1990. Although there are around nine local species that attack unprovoked, only three are associated with fatal attacks here: bull sharks, tiger sharks, and great whites. Together they're responsible for nearly half all attacks, whether fatal or not. The global fatality rate from shark attack is around 16% and that's close to right for Australia too.

Australia has around 2.5 million recreational surfers, but only around 400,000 scuba-divers. Although attacks on surfers see most of the media reporting here, most reported attacks are actually on divers, including divers involved in spearfishing.

That being so, I'm not even sure what 'accidental bite' means to a shark -- they'll bite opportunistically to see how it tastes and if they like it, they'll bite it some more. Since some species don't put people down after a single bite, we can assume that they're actively trying to eat you. There's some progressive language here toward calling an attack a 'negative encounter', but to me that looks like social management. Do mice have 'negative encounters' with cats, or are they just another prey species to an opportunistic hunter?

Perhaps we have a species blind spot here. We might be an apex predator *on* the water, but splashing around *in* or *under* it, not so much. Maybe that does our heads in.

Regarding the social impact of the movie Jaws in Australia, it resulted in a lot of bigger grey nurse sharks getting spearfished for trophies, and this promoted as a public safety service. And it resulted in adventure boats fishing for great whites just for the thrill of watching them biting. Stupid movie, stupid news media, stupid adventure industry.

But meanwhile, in an alternative reality, off the South Coast of New South Wales is an island called Montague/Barunguba Island where there are juvenile Australian fur-seals being raised by bachelors, there are little penguins in a rookery along with 15 other bird species, and in a trench off the island you can see dozens of grey nurse sharks resting during the day. You can dive or snorkel with any of these critters, and that happens most weekends.

There are vast amounts for ordinary people to learn from watching these animals co-exist and I'm glad that they're all around. We can do much better than reducing our marine understanding to pop sensationalism. [https://www.visitnsw.com/destinations/south-coast/batemans-bay-and-eurobodalla/montague-island]
