What is oz meaning?

Oz is a term that is commonly used to refer to Australia. It is believed that the term "Oz" was derived from the abbreviation of the "Australian" to "Aussie," which sounds like the first syllable of "Australia." The use of the term 'Oz' became popular amongst Australians after it was popularized in the 1939 film, "The Wizard of Oz." However, it's not uncommon to hear non-Australians use the term to refer to the country.
