Northern Australia Hammerhead Shark Tagging Program - Fact Sheet

Northern Australia has two large species of hammerhead sharks, the scalloped hammerhead and great hammerhead. They can migrate long distances. This makes it difficult to manage them, because impacts in one place may affect the whole population.

To properly understand and manage the threats facing hammerhead sharks, we need to learn how the sharks move across all of the northern Australian states, including any movements between Papua New Guinea and Indonesia. We will tag hammerhead sharks with satellite tags to track where they go, and collect small tissue samples to help see which populations are connected.
