* G'day: This is the most iconic and widely used greeting in Australia. It's short for "good day" and can be used in almost any situation.
* Hey: This is a casual greeting that can be used with friends, family, and acquaintances.
* How are you going? This is a more formal greeting than "G'day" or "Hey." It's often followed by "Not bad, yourself?" or "Good, thanks."
* Morning: This is a common greeting used in the mornings, often shortened to "Mornin'".
* Afternoon: This is a greeting used in the afternoons, often shortened to "Arvo".
It's important to remember that Australians are generally friendly and relaxed, so don't worry about using the "wrong" greeting. Just be polite and smile!
