Final report: A14 Identification of near-shore habitats of juvenile white sharks in south-western Australia
Abstract:

Understanding the spatial dynamics and behaviour of the juvenile life stage of the white shark, Carcharodon carcharias, from the southern-western Australian (SWA) population is crucial to deriving a total abundance estimate and informing future management plans.

The Head of the Great Australian Bight, including several marine parks – Great Australian Bight, Murat, Western Eyre (Commonwealth) and Nuyts Archipelago (State) Marine Parks, appear to be important habitat for white sharks of all life stages. However, further on-water activity and an expansion of the UAV survey into waters west of the Head of Bight would assist with characterising the diversity of this region and provide greater opportunity for deeper engagement with the Traditional Owners of Country.  Although difficult to establish effective offshore monitoring, targeted surveys of the Murat (e.g. around Yatala Reef) and Western Eyre Marine Parks would also increase our understanding of white shark distribution as well as biodiversity in the GAB.

Project A14 - Identification of near-shore habitats of juvenile white sharks in south-western Australia

Juvenile white sharks frequent inshore regions where they may be observed with drones. Observations of juveniles as well as adult white sharks have been made around the Head of the Great Australian Bight. Image: Dirk Holman.

Sibling DNA matches provide key data for white shark population estimates

Looking for brothers and sisters among juvenile white sharks has provided the final pieces of information needed to estimate the size of populations in Australian waters.
