Auslan is recognised by the Australian Government and is spoken by many Australian deaf people. Australian Aboriginal languages, of which there are approximately 290-363, have recognition – though only a few are popularly spoken by Australian Indigenous people, including: Wiradjuri, Pitjantjatjara, Kalaw Lagaw Ya, Ngaanyatjarra, Warlpiri and Australian Kriol. Many government departments and agencies, as well as private services, have adopted the use of Mandarin Chinese as a de facto second language, reflecting Australia's large Chinese population and strong trade and diplomatic ties to China.
