There have been more than 1,100 individual investigations of shark bites in Australia since 1791, according to the Australian Shark Incident Database. 

In 2022, Australia had the second-highest number of unprovoked shark bites – with the United States being first.  Although they had 16% of the world's total shark bites, Australia did not record any deaths from the bites until February 2022, when a shark attack killed a man outside Sydney beach. It was the city's first fatal attack since 1963.

Earlier this month authorities searched for the remains of a 55-year-old surfer after he got bitten by a shark the length of a "sedan" off of Granites Beach in South Australia.

In August, a man in his 40s was rushed to a hospital after he got bitten by a shark on a beach outside of Sydney.
