Usage notes

• The term is occasionally used, mostly by non-Australians, to refer to the country of Australia (for example, “back in Aussie”). This usage is very rare amongst Australians, who are more likely to use the term “Oz”. The exception seems to be sporting chants, such as “Aussie! Aussie! Aussie!” and “Come on, Aussie, come on!”, which appear to apply this usage.
