Report finds no increase in local white shark population

​A newly-released CSIRO report has found that there has been no increase in the southern-western shark population, part of which can be found off Western Australia, and that there has been a downward trend in adult numbers since the early 2000s.

Researchers found there are two distinct white shark populations in Australia, the southern-western white shark population (covering South Australia, Western Australia, western Victoria) and the eastern Australasian white shark population (New South Wales, Tasmania, Victoria, Queensland and New Zealand).

Total population numbers across Australia are still inconclusive, however southern-western adult numbers are estimated at 1460, with the eastern Australian adults numbered at 750.

In the report, CSIRO also calls for increased research funding into the southern-western population.

WA is managing shark mitigation through a multi-faceted strategy using innovative technologies, including the deployment of new Shark Monitoring Network buoys and a subsidy for independently verified shark deterrent devices. Additional funding has been allocated for increased coastal drone surveillance and beach patrols, as well as a new emergency numbering system for beaches and beach enclosure barriers.
