Whales and Woodside

For decades, Woodside has had a robust approach to identifying and managing potential environmental impacts and risks associated with our offshore activities.

Advancing Whale Research in Australia

For more than 30 years, we have invested in funding research into whale seasonality, distribution, and abundance in Western Australian waters. Our total investment in whale research, alongside our joint venture partners, is approximately A$30 million, making Woodside one of the largest funders of whale research in Australia.

Based on a wealth of scientific studies, this collective knowledge has driven Woodside’s approach to management and mitigation measures to avoid or minimise any impacts on individual whales and the broader recovery of whale populations in Australia. The funded research has resulted in over 20 papers in international peer-reviewed scientific journals, supporting industry, state governments and the Commonwealth government in reducing potential threats, supporting conservation management, and tracking the recovery of whale populations.

More recently, our research into the pygmy blue whale was recognised at the annual Australian Petroleum Production and Exploration Association Conference where Woodside received the Environment Project Excellence Award for “scientific innovation and collaboration enabling effective management of pygmy blue whales in Australia’s northwest”. 

30 Years of Humpback Whale Knowledge

The Western Australian humpback whale population migrates up and down the WA coast every year, travelling from feeding grounds in Antarctic waters to their calving habitat in WA’s warm tropical waters. 

The WA coast is a hot spot for whale watchers, particularly off the Ningaloo Coast. 

These fantastic creatures cover vast distances yearly and have one of the longest migrations of any mammal on earth. In the eastern Indian Ocean, Humpback whales migrate from Antarctica to the Kimberley (in northern Western Australia), covering over 5,000 kilometres1 in as few as 28 days – that is like swimming from Perth to Adelaide and back in less than a month.  

In collaboration with the Australian Institute of Marine Science and Western Australian Museum, Woodside celebrates over 20 years of scientific partnership and research.

The WA coast is one of 14 distinct population segments1 , along with the West Indies, Hawaii, Brazil and Eastern Australia, to name a few. Unfortunately, during the 1970s, the estimated humpback whale population in WA fell sharply to around 800 due to commercial whaling. Since then, WA humpback whale population numbers have recovered dramatically to more than an estimated 30,000 in 2021. Humpback whales have now been removed from the Australian Environment Protection and Biodiversity Conservation (EPBC) Act threatened species list as a result of full population recovery. 

Woodside is committed to applying a continuous improvement approach in how we manage our offshore activities. We also uphold all relevant environmental management standards to ensure the health of the humpback whale population. 

Moving Forward: The Future of Pygmy Blue Whale Research

We are now applying the same science-based mitigation and management approach to pygmy blue whales. Woodside has been supporting pygmy blue whale research since the early 2000s, through partnerships with the Australian Institute of Marine Science (AIMS), the Australian Antarctic Division and the Centre for Whale Research (CWR).      

AIMS is Australia’s tropical marine research agency renowned for its global science excellence, the Australian Antarctic Division (AAD) deliver the Australian Antarctic Program to support Australia’s science and permanent presence in Antarctica and the CWR (Western Australia) Inc. is a non-profit research institute established to conduct scientific research into marine mammals.

Woodside’s partnership seeks to understand the movement and behaviours of pygmy blue whales in Australia’s northwest through research. Using the latest satellite tracking technology and this data has been a vital input into modelling the likely response of pygmy blue whales to underwater noise emissions. This will inform the management of Woodside’s offshore activities to avoid or minimise potential impacts and contributes to broader industry knowledge around habitat management and conservation efforts. Learn more about our pygmy blue whale research in our 2022 Sustainable Development Report.

Overall, we remain committed to supporting the collection of credible whale science through our research and to support the long-term management of whale populations in the regions where we operate
