Management of marine turtle nesting in Australia has traditionally focused on large northern rookeries; however, limited studies have investigated nesting at the southern edge of species’ nesting distributions. In New South Wales (NSW), nesting by green and loggerhead turtles is increasing and extending south into environments characterised by cooler sand temperatures, high human activity, and complex coastal land management. These emerging nesting sites present both opportunities and challenges. NSW beaches may function as climate refugia under warming conditions, yet nests are exposed to threats including cool and variable incubation conditions, coastal erosion, and human disturbance. Effective management therefore requires adaptive, place-based approaches and strong collaboration with local communities. This presentation will examine recent trends in turtle nesting in NSW and discuss current monitoring and management responses led by NSW National Parks and Wildlife Service in partnership with community and non-government organisations. It will explore the role of citizen science, collaboration and local knowledge in providing a better future for these threatened marine reptiles. By highlighting the implications of climate-induced changes to nesting patterns for management and policy, we discuss how collaborative approaches can support the conservation of marine megafauna in rapidly changing coastal systems.
