Variation Relative to many other national dialect groupings, Australian English is relatively homogeneous across the country. Some relatively minor regional differences in pronunciation exist. A limited range of word choices is strongly regional in nature. Consequently, the geographical background of individuals may be inferred if they use words that are peculiar to particular Australian states or territories and, in some cases, even smaller regions. In addition, some Australians speak creole languages derived from Australian English, such as Australian Kriol, Torres Strait Creole and Norfuk. Academic research has also identified notable sociocultural variation within Australian English, which is mostly evident in phonology.

Preference for some synonymous words also differ between states. Garbage (i.e., garbage bin, garbage truck) dominates over rubbish in New South Wales and Queensland, while rubbish is more popular in Victoria, Tasmania, Western Australia and South Australia. Additionally, the word footy generally refers to the most popular football code in an area; that is, rugby league or rugby union depending on the local area, in most of New South Wales and Queensland, and Australian rules football elsewhere. In some pockets of Melbourne & Western Sydney it will refer to Association football. Beer glasses are also named differently in different states.

Secret Santa () and Kris Kringle are used in all states, with the former being more common in Queensland. South Australia The most pronounced variation in phonology is between South Australia and the other states and territories. The trap–bath split is
