Australia is home to more than a quarter of the world's shark and ray fauna. These species contribute to healthy oceans as top predators in the marine ecosystem, but many of them are declining. We provide knowledge and advice to help manage the many threats to shark and ray populations.
Answers to the questions we are most often asked about white sharks, such as where they are, how many there are, how we tag and track them, and why they need protecting.
In collaboration with various partners and funding agencies, we’ve deployed some 250 electronic tags on 210 different white sharks since 2000 (some sharks are tagged with more than one type of electronic tag).
Acoustic tagging is the primary tool used to collect data on white sharks
Our scientists are using genetic and statistical analyses, electronic tagging and aerial survey techniques to develop the first estimates of how many white sharks there are in Australia, and whether their numbers are rising or falling.
Our research has revealed where white sharks go and how they behave, identified nursery areas and eastern and western populations, and developed techniques for measuring their abundance.
