Many Australians are very informal, and in such a setting, a shortened version of 'Good day' could be used; 'G'day' (pronouned 'gidday'). Such a greeting could then be followed by an informal 'How's it going?' or 'How ya going?'.
Also, just Hi or Hello will do just fine. (Neither of the first two mentioned greetings sound right to an Australian ear if said with a US accent.)
Since English is the most widely spoken language in Australia, it would be completely acceptable to greet a person with 'Hello'. Similarly, depending on the formality of the situation, other acceptable greetings would be 'Good morning/afternoon/evening' or 'Hi'.
