  Although English is not the official language of Australia in law, it is the de facto official and national language. Australian English is a major variety of the language with a distinctive accent and lexicon, and differs slightly from other varieties of English in grammar and spelling. General Australian serves as the standard dialect. The Australian sign language known as Auslan was used at home by 16,242 people at the time of the 2021 census.
  
  At the 2021 census, English was the only language spoken in the home for 72% of the population. The next most common languages spoken at home were Mandarin (2.7%), Arabic (1.4%), Vietnamese (1.3%), Cantonese (1.2%) and Punjabi (0.9%).
  
  Over 250 Australian Aboriginal languages are thought to have existed at the time of first European contact. The National Indigenous Languages Survey (NILS) for 2018–19 found that more than 120 Indigenous language varieties were in use or being revived, although 70 of those in use were endangered. The 2021 census found that 167 Indigenous languages were spoken at home by 76,978 Indigenous Australians — Yumplatok (Torres Strait Creole), Djambarrpuyngu (a Yolŋu language) and Pitjantjatjara (a Western Desert language) were among the most widely spoken. NILS and the Australian Bureau of Statistics use different classifications for Indigenous Australian languages.
