Great white shark Carcharodon carcharias (Vulnerable)

The waters around Dyer Island are an important seasonal feeding ground for great white sharks. Researchers working through Dyer Island Conservation Trust have demonstrated a decrease in white shark sightings around the island since 2017. This has raised concerns that the local population may be declining, and it has been postulated that this is due to predation by orcas (Orcinus orca) as well as over-fishing, pollution and climate change.
