Australian English demographics change from state to state but it's only slight compared to the variety of British and American English accents. A mixture of Broad and General Australian English accents can be heard across Southern and Western Australia, while Broad Accents are more common by themselves in states such as the Northern Territory and Central Australia. Large metropolitan areas such as Melbourne, Sydney and Southeast Queensland share large portions of each accent. Cultivated Australian English is rare compared to the rest but can be observed in the upper and middle classes, from migrant families with recent British ties (up to a century and a half in some cases) and in performing arts communities where pronounced English is of most benefit.
