New South Wales Government proudly acknowledges the Aboriginal community of NSW and their rich and diverse culture and pays respect to their Elders past, present and future. The NSW Government acknowledges Aboriginal people as Australia’s First Peoples practising the oldest living culture on earth and as the Traditional Owners and Custodians of the lands and waters. We acknowledge that the people of the Barkandji, Barapa Barapa, Maljangapa, Maraura, Muthi Muthi, Ngiyampaa, Tati Tati, Wadi Wadi, Weki Weki, Wemba Wemba, Wiradjuri and Yorta Yorta Nations hold a significant connection to the lands of the NSW Murray and Lower Darling Water Resource Plan Area. The NSW Murray and Lower Darling Water Resource Plan Area holds great areas of spiritual, cultural and economic importance to First Nations people and NSW recognises the connection of the water to the people of these nations. We recognise the intrinsic connection of Traditional Owners to country and acknowledge their contribution to the management of the NSW Murray and Lower Darling Water Resource Plan Area landscape and natural resources. NSW Department of Planning, Industry and Environment understands the need for consultation and inclusion of Traditional Owner knowledge, values and uses in water quality planning to ensure we are working towards equality in objectives and outcomes. NSW Department of Planning, Industry and Environment is committed to continue future relationships and building strong partnerships with our First Nations People. We thank the Elders and representatives of the Barkandji, Barapa Barapa, Maljangapa, Maraura, Muthi Muthi, Ngiyampaa, Tati Tati, Wadi Wadi, Weki Weki, Wemba Wemba, Wiradjuri and Yorta Yorta Nations and Aboriginal community members who provided their knowledge throughout the planning process. © State of New South Wales through the Department of Planning, Industry and Environment, 2019.
