Head\u2010width to snout\u2010vent length ratio (H:SV) and head\u2010width to trunk length ratio (H:T) were measured and sex was defined at necropsy. Similar data were obtained from a previous study in Sydney, New South Wales (NSW).

In all cases, H:T was as good or superior to H:SV. H:T cut\u2010points optimized for female sexing or both sexes ranged from 0.20 to 0.23 depending on State and adult status.
