Sharks contribute to healthy oceans as top predators in the marine ecosystem. But some sharks, such as the iconic white shark, are under threat and vulnerable to depleting numbers. We provide knowledge and advice to help manage conservation for a number of species under threat.

Breakthrough science to understand the lives and movements of white sharks

Our research is providing insight into white shark movement patterns and behaviour, juvenile nursery areas, and adult population estimates for the eastern and southern-western Australasian populations.

[Music plays and the CSIRO and Marine Biodiversity Hub logos appears and an image appears of a white shark swimming and small fish appear swimming around the shark and text appears: White sharks are vital to marine ecosystems]

[Image changes to show a white shark swimming and a school of fish swimming beneath it and text appears: They are vulnerable to threats and protected internationally]

[Image changes to show a close view of three crew members on a boat hauling on a rope and text appears: In a landmark study, we used a cutting-edge genetics tool…]

[Image changes to show a white shark swimming through a school of fish and text appears: … to estimate how many white sharks there are]

[Image changes to show a simulation of a white shark swimming along the ocean bed and text appears: In Australian waters there are two populations – eastern and southern-western]

[Image changes to show a close view of a rope in the water and text appears: We estimate there are 5,500 white sharks living off Australia’s east coast]

[Image changes to show a grey nurse shark swimming in the ocean and text appears: This science is being used for other species too, such as grey nurse sharks and tuna]

[Image changes to show a simulation of an aerial view of a circle around a white shark swimming between Receiver points A, B, and C and text appears: Together with the NSW Department of Primary Industries, we’re also tracking white shark movements and behaviour…]

[Image changes to show a close view of a hands holding a shark by the fin in the water and checking the satellite tag on the fin and text appears: … using satellite and acoustic tags]

[Image changes to show a map of a shark’s journey up and down the coast of Victoria and New South Wales and text appears: White sharks can travel thousands of kilometres, even to New Zealand but they rarely cross the Bass Strait]

[Image changes to show an animation of a white shark swimming past a receiver towards the camera along the ocean floor and text appears: Our breakthrough research is providing new and innovative insights…]

[Image changes to show a white shark swimming with a school of tuna and text appears: … to understand the lives of white sharks, and help with ongoing management]

In a landmark study, we used a cutting-edge genetics tool to estimate how many white sharks there are. We’re also tracking them to understand more about their movements and behaviour.
