Offshore wind energy will play a vital role in Australia’s efforts to reach net zero emissions by 2050. However, its development will introduce new pressures on the marine environment, including novel impacts on local marine mammals. Understanding these impacts is essential to ensure they are effectively assessed and mitigated to support responsible project planning and consenting.
Drawing on research and case studies from established offshore wind markets in the UK and Europe, this presentation will outline key potential impacts on marine mammals, including underwater noise from construction, displacement, barrier effects, and for floating turbines potential entanglement risks. It will also explore the challenges in assessing and managing these risks, highlight data gaps, and examine the effectiveness of mitigation strategies—such as noise reduction technologies and adaptive management approaches. Consideration will be given to the applicability of these strategies to the Australian context, taking into account local species and environments.
This insight will help guide future efforts in assessing and managing the risks to marine mammals, ultimately informing how Australia can develop offshore wind projects that minimise harm to these species while advancing renewable energy goals.
