Language

English is the national language. Australian English has a unique accent and a small number of unique terms, some of which have found their way into other dialects of the English-speaking world. It has less internal dialectal variation than either British or American English. Grammar and spelling are largely based on those of British English. According to the 2006 census, English is the only language spoken in the home for close to 79% of the population. The next most common languages spoken at home are Italian (1.6%), Greek (1.3%) and Cantonese (1.2%); a considerable proportion of first- and second-generation migrants are bilingual.

Between 200 and 300 Indigenous Australian languages are thought to have existed at the time of first European contact, of which only about 70 have survived. Many of these are exclusively spoken by older people; only 18 Indigenous languages are still spoken by all age groups. At the time of the 2006 Census, 52,000 Indigenous Australians, representing 12% of the Indigenous population, reported that they spoke an Indigenous language at home. Australia has a sign language known as Auslan, which is the main language of about 5,500 deaf people.
