route, and they created freshwater wells at Yalangbara by plunging their digging sticks into the sand, after which the digging sticks turned into a variety of plant species. There is still freshwater to be found under the sandy beach, and is believed to have healing properties. A site known as Balma, high among the sand dunes, is of particular significance as it was here that the Djang'kawu sisters gave birth to the first of the Rirratjingu clan. Access to this site is restricted. From Yalangbara the Djang'kawu travelled west, establishing the Dhuwa moiety of the Yolŋu people. The Marika family, who trace their ancestry to the original Dhuwa moiety, are the traditional owners of the land, and they manage the area's rich biodiversity. They are also custodians of Djang’kawu law, which is expressed in ritual ceremonies and art. Many members of the family started producing paintings when they lived at the Yirrkala mission from 1935 onwards. The Yalangbara: art of the Djang’kawu touring exhibition, instigated by Banduk Marika and developed with the assistance of other family members and the Museum and Art Gallery of the Northern Territory at Darwin, opened at the National Museum of Australia from 7 December 2010. This was the first major survey exhibition of the Marikas' work, and covers around 50 named sites in the Yalangbara peninsula that were traversed by the Djang’kawu journey. It followed a 2008 monograph of the same name, edited by Margie West and produced in partnership with Banduk Marika and other members of the family. Heritage listing Yalangbara was registered as an Aboriginal sacred site with the NT's Aboriginal Areas Protection Authority in 1983. Thanks to the work of Banduk Marika, her nephew Mawalan 2 Marika, anthropologist Geoffrey Bradshaw and others, which included a detailed heritage assessment (2000), Yalangbara was included for listing on the Australian Heritage Commission's Register of the National Estate in 2003. The Register of the National Estate was frozen in 2007, and Yalangbara is not yet actually listed under the superseding Commonwealth Heritage List. Under the EPBC Act, the Minister for the Environment "determines which places the Australian Heritage Council will assess for the National Heritage List and Commonwealth Heritage List", and it has been listed for assessment by 30 June 2022. It was added to the "Finalised Priority Assessment List for the National Heritage List for 2018-19", with the area being defined as from Bawaka Road
