This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Development of regional modelling and risk assessments to inform offshore renewable decision-making". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia is entering a phase of rapid offshore renewable energy (ORE) development, with several regions earmarked for wind farms on the eastern and south-eastern coasts. In considering the environmental acceptability of wind energy projects, the Department of Climate Change, Energy, the Environment and Water (DCCEEW) will assess potential risks to the recovery of populations listed under the Environment Protection and Biodiversity Conservation Act (EPBC Act 1999). The assessment process will consider cumulative environmental impacts at a regional or even ocean basin-scale, in addition to environmental factors specific to ORE. Additionally, the National Offshore Petroleum Safety and Environment Authority (NOPSEMA) has identified the need for improved understanding on species, processes and industry activities to support impact and risk assessment. This project will demonstrate the use of two kinds of modelling (whole-of-ecosystem modelling and individual species modelling) to estimate the impacts and risks of installing ORE infrastructure in the Gippsland declared region. The project will use the Impact pathways defined by DCCEEW to structure its approach and methods, and will work with DCCEEW and NOPSEMA to identify priority species and associated data needs. The project will use the recently declared Gippsland region as a case study, together with the 12 ORE impact pathways identified by DCEEW, to contextualise the quantitative modelling and cumulative risk calculations that will be performed. Outputs • Species-specific population models for key threatened and migratory species for the Gippsland ORE region [spatial outputs] • Outputs from Whole of Ecosystem (WoE) modelling [risk-based impact spatial outputs] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Assessing the vulnerability of southern right whale and blue whale populations to disturbance from windfarm developments". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia is entering a phase of rapid offshore renewable energy development, with several marine regions earmarked for wind farms. Underwater noise generated by the construction and operation of large wind turbines may affect species such as whales that rely on their acoustic environment to feed, breed and survive. This desktop study will use available data and expert opinion to develop interim Population Consequences of Disturbance (PCoD) models for blue whales and southern right whales in relation to one or multiple offshore wind farm developments off Portland and Gippsland, Victoria. This method has been used internationally to assess the impacts of offshore wind farm developments, including for harbour porpoises in British waters. The model will follow a decision pathway to consider factors such as: • when and where development activities overlap with populations; • the proportion of populations affected; • the life stages and reproductive phases affected; and • the chances of repeated disturbance. The model will be used to predict the timing and location of cumulative impacts of the proposed activities at a regional scale, identifying which species are at ‘high-risk’ and are a priority for further research; noise levels mitigation measures required to adequately reduce the risk of compromised population viability; what research is needed to better understand population-level consequences of noise; and which mitigation measures can substantially reduce the risk of population-level effects. The PCoD model will be able to be updated as new data become available, and will be relevant for assessment against other ocean-based activities such as oil and gas infrastructure and carbon capture and storage. Outputs • PCoD model and risk assessment outputs [dataset] • Species distribution maps, as derived for existing observational data [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Unbroken whispers: the ripples connecting sea kin". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Knowledge, in all its forms, is key to effectively protecting and recovering threatened and migratory whales and dolphins. Indigenous ecological knowledge (IEK) has guided Indigenous peoples through many uncertain climate and ecological fluctuations. IEK has also been used as part of protected area and species management for many thousands of years. More recently, IEK has shown huge potential to contribute to our understanding of threatened and migratory whales and dolphins, but this knowledge has not historically been collated, analysed or properly considered. Consequently, there is an absence of Indigenous perspectives and use of cultural knowledge informing the protection and recovery of EPBC listed threatened and migratory species. This Indigenous-led project will identify and share (where appropriate) cultural knowledge of relationships with whales and dolphins, and connections between land, sea and sky. Indigenous communities will participate in research that explores cultural ideology around kinship and responsibilities to kin, through expressing the knowledge, values and concerns they hold for whales and dolphins. The acquired knowledge and methods will support the cultural governance of sea Country by Indigenous communities and organisations, and policymaking, implementation and review by government agencies in relation to resource use and conservation. Outputs • GIS visualisation package of key geospatial layers related to connecting land and sea in the context of cultural keystone species [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Potential impacts of offshore wind developments on eastern Indian Ocean pygmy blue whales (Balaenoptera musculus brevicauda)". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Pygmy blue whales (Balaenoptera musculus brevicauda) are listed as Endangered under the Environment Protection and Biodiversity Conservation Act (EPBC 1999), and their distribution and Biologically Important Areas (BIAs) overlap with areas proposed for offshore renewable energy (ORE) development in Western Australia, South Australia, Victoria, and potentially NSW. This project will quantify the distribution and location of areas of residency (e.g., foraging) for eastern Indian Ocean pygmy blue whales, where these overlap with proposed ORE developments, and assess the potential impacts of these developments to the species in addition to existing impacts from other anthropogenic activities. The outputs from this project will assist government, regulators, proponents, and other stakeholders in the assessment and mitigation of ORE projects to this threatened species, and will identify future research and associated data collection needs. Outputs • Spatial layers quantifying the relative distribution including migratory corridors and foraging areas across the known eastern Indian Ocean pygmy blue whale range [dataset] • Spatial layers of habitat suitability distribution [dataset] • Spatial layers for human activities identified as key pressures in this study [dataset] • Spatial layers of cumulative impact score across the species' range including potential threats from ORE and existing threats from other industries [dataset] • Final project report [written]
