Australian English /iː/, /ɪ/, and /ɪə/ exhibit almost identical average first (1) and second (2) formant frequencies and differ in duration and vowel inherent spectral change (VISC). The cues of duration, 1 × 2 trajectory direction (TD) and trajectory length (TL) were assessed in listeners' categorization of /iː/ and /ɪə/ compared to /ɪ/. Duration was important for distinguishing both /iː/ and /ɪə/ from /ɪ/. TD and TL were important for categorizing /iː/ versus /ɪ/, whereas only TL was important for /ɪə/ versus /ɪ/. Finally, listeners' use of duration and VISC was not mutually affected for either vowel compared to /ɪ/.
