Chelodina longicollis is an opportunistic carnivore that obtains its food from a wide variety of sourcesplankton, nekton, benthic macro-organisms, carrion, and terrestrial organisms that fall upon the water. Although there are some quantitative differences between the littoral components of the diet and the composition of the littoral fauna, these can be attributed to differences in accessibility or 'noticeability' among prey species. There is no evidence to suggest that C, longicollis is selective in what it eats, within the confines of carnivory. Comparison of the diet of C. longicollis with those of other sympatric chelids reveals considerable overlap; the relevance of this to geographic variation in abundance of the species is discussed.
