This chapter revisits earlier work by Pam Peters and Peter Collins on colloquial Australian English in the World Atlas of Varieties of English (WAVE). Forty two morphosyntactic WAVE features were extracted from the blogs section of the 1.9 billion-word Corpus of Global Web-based English (GloWbE) and analysed, with a view to achieving a superior level of empirical reliability than was possible in the earlier study, limited as it was to evidence from small ‘gappy’ corpora supplemented where necessary by impressionistic judgements. The scope of the earlier study is also broadened, through the introduction of an intervarietal perspective which compares Australian English with British, American, Irish and New Zealand English, and through the adoption of an onomasiological methodology that systematically compares frequencies for the non-standard features with those of their standard counterparts. The findings challenge the stereotype of Australian speakers as uniquely ‘laid back’ in their use of English. It emerged that American speakers, not Australian, were the most prolific users of the non-standard colloquial features investigated, be they broadly acceptable or socially stigmatised.
