Description

The Australian sea lion (Neophoca cinerea) is Australia’s only endemic pinniped and is listed as Endangered under the EPBC Act. Populations have declined by more than 60% over the past 40 years and are vulnerable to threats including fisheries bycatch, disease, pollution, marine debris entanglement and climate change. Improving knowledge of abundance, demography and critical habitat use is essential for evaluating threats and guiding recovery actions, but is difficult due to the species’ breeding biology, longevity, seafloor foraging behaviour and use of remote breeding sites.

This project developed and applied cost-effective methods to improve monitoring of Australian sea lion populations, particularly in under-surveyed regions exposed to anthropogenic pressures. It included four linked components: (1) helicopter and remote-camera surveys of breeding sites in the Recherche Archipelago; (2) drone surveys of selected breeding and haul-out sites in Western Australia and South Australia; (3) processing and analysis of long-term demographic data from the microchipped Seal Bay population; and (4) continued deployment of underwater cameras to identify habitat use, foraging behaviour and potential risks.

The project was co-designed with Indigenous partners, including Yalata Anangu Aboriginal Corporation, Far West Coast Aboriginal Corporation and Esperance Tjaltjraak Native Title Aboriginal Corporation. Indigenous partners contributed to delivery of project components, including drone-based monitoring and field activities, supporting Indigenous leadership in the use of new technologies for sea lion monitoring and Healthy Country management.

Outputs included updated abundance and breeding-site information, validated drone survey methods, improved workflows for demographic analysis, and additional animal-borne camera data on critical habitats. These data and methods support implementation of the Australian Sea Lion Recovery Plan, long-term state government monitoring, assessment of cumulative impacts and recovery actions, and conservation planning linked to Sea Country values.
