A high seas treaty could help rebuild populations – but time is running out.
You’re more likely to drown at a beach than be killed by a shark. But there are things people can do to reduce the already low risk even further.

Estimating shark numbers is extremely difficult and very contentious.
New research has used genetic analysis in a world-first effort to accurately estimate Australian and New Zealand white shark numbers.
White sharks’ ability to stay warm in cold water makes them efficient long-range hunters.
Fatal shark bites are very rare. But the stats do suggest that the likelihood of an attack proving fatal is higher in Australia - probably because our waters are home to the “big three” dangerous species.

Loving our monsters? We’ll learn more by researching sharks than by kiling them.
The best way to guard against shark attacks is to study them, not kill them. Because while the alleged “shark boom” almost certainly not real, the more we know about sharks, the better.
