In Australian English, "goodnight" is typically said as "goodnight" or "night." Australians may also use the informal slang term "nighty night" or "night night" in casual settings. The pronunciation of "goodnight" in Australian English is similar to British English, with a clear "g" sound at the beginning and a slight emphasis on the "igh" diphthong.
