Australian English (AusE, AusEng, AuE, AuEng, en-AU) is the set of varieties of the English language native to Australia. It is the country's common language and de facto national language; while Australia has no official language, English is the first language of the majority of the population, and has been entrenched as the de facto national language since European settlement, being the only language spoken in the home for 72% of Australians. It is also the main language used in compulsory education, as well as federal, state and territorial legislatures and courts.
