Whereas other English accents vary more based on specific regions, the Australian accent lacks this regionalization and instead holds a 3 tiered system of Broad, General and Cultivated Australian accent (reference 1).
Depending on the distinctness of the accent, it will fall along this spectrum from broad to cultivated.
Broad Australian tended to play up stereotypes such as:
1) 'eye' in fine, ride → 'oi' in choice, coin
Whereas the Cultivated Australian accent may not make that diphthong change.
2) The diphthong (sound formed by the combination of two vowels in a single syllable, in which the sound begins as one vowel and moves toward another) in 'ou' in south, loud, out starts out as 'eh' in dress instead of 'ah'.
The Australian accent is a bit tricky in that many of its differences are related to vowel pronunciation and its variations instead of consonant differences.
