Australian English Phonology

Vowel System

/ɔ ɔː/ in the table below are in two different places. This is because they could be considered in either position. /ɔ/ is open-mid rather than close-mid like the other mid vowels, and it is very laxly rounded, if rounded at all. /ɔː/ is used only in the word "gone" [gɔːn]. It's not an allophonic variation of /ɔ/ or /oː/. It's worth noting that if we consider /ɔ(:)/ unrounded, then all unrounded vowels have long/short pairs, and rounded vowels are long, aside from /u/, which doesn't contrast with a unrounded vowel.

Hiatus

Like many languages, Australian English forbids hiatus. Here is how it resolves the problem obtained when two vowels collide:

If the ffirst vowel is in set (1), then [ɹ] is added:

(1) ɪː eː aː oː øː ə uə~uː

If the fist vowel is in set (2), then [j] is added:

(2) æi ɪi ɑe oi

If the first vowel is in set (3), then [w] is added:

(3) æɔ ʉː ɔʉ

If the first vowel is in set (4), then it can’t end a word:

(4) ɪ e æ æː a ɔ u

Examples:

Here is a fair amount of far and away the poorest examples of Australian hiatus. These’re only on display if you can see ’em. I always saw the boy in the window, until a cow interfered with you over there. Keep low or you might be hit.
