Australia's ten shark hotspots, and what the numbers actually say

Ten places account for 29% of Australia's recorded shark incidents. The research behind our 90-second map, including the figures that did not fit.

The Australian Shark-Incident Database records 1,295 encounters between 1791 and today, and every one of them carries a coordinate. That is unusual — most historical datasets give you a place name and leave you guessing. It is what made the shark incident map possible at all.

Ten places account for 29% of the record. Here is what the research turned up while making the video, including the parts that did not fit in ninety seconds.

The ten hotspots

These are the clusters the map itself draws: incidents grouped into roughly 25 km cells, then merged where neighbouring cells resolve to the same place, so a city straddling a cell boundary counts once.

Read the fatal share column with care - it is a share of recorded incidents, and the record starts in 1791. The pattern it mostly describes is when a place was busy, not how dangerous its water is.

Townsville is the strangest entry

Twenty-one incidents, and fourteen of them fatal — a 67% fatality share, by far the highest of any hotspot. Then nothing at all after 1952.

That combination is the giveaway. It is not a record of a uniquely dangerous stretch of water; it is a record of an era. Minor bites went unreported, and someone bitten in Ross Creek in 1910 had almost none of the trauma care that a person bitten today would receive. Every hotspot's fatality share is inflated by its oldest entries, and Townsville is nearly all old entries.

The shark that has never killed anyone here

Wobbegong appears 215 times in this database. Deaths: zero.

It is the fourth most frequent species in the record, and it has never caused a fatality in it. Grey nurse — the one with the mouthful of visible teeth that makes it a stock photo for menace — appears ten times, also with no deaths.

Species matters enormously, and "shark attack" flattens it into one word.

A third of the record is provoked

420 of 1,295 incidents are classified as provoked: the person was spearfishing, fishing, or handling the animal. Every single fishing and spearfishing incident in the database is classified that way.

Thursday Island is the clearest case — 58% provoked, and 21 of its 24 incidents involve tiger sharks in water that was worked commercially for pearl. Those are not swimmers being hunted.

Bull sharks go inland

Forty percent of Gold Coast incidents happened in rivers, not surf. Eight of Perth's are up the Swan. Bull sharks tolerate fresh water and travel a long way up estuaries, which is why the map has dots well inland of the coast — and why people are sometimes surprised to find them there.

What the counts do not mean

Incidents roughly tripled between the 1970s and the 2010s. That tracks beach participation and reporting practice, not shark numbers — which have fallen sharply worldwide, mostly through fishing.

The hotspots are where people swim, not where sharks are most dangerous. Sydney tops the list with 145 incidents because Sydney has beaches, a harbour and five million people, and a record that starts in 1791.

You can slice all of it yourself on the interactive map — by year, species, activity, season or outcome.
