Abstract Species composition of plants present in the stomach contents of 34 road-killed swamp wallabies, W. bicolor, on North Stradbroke Island, south-east Queensland, was investigated, and related to seasonal variations in nitrogen and fibre contents of plants in the study area. W. bicolor consumed a wide range of plant categories including shrubs, forbs, grasses, ferns and fungi. Among these, grasses, followed by shrubs, were the major component of the stomach contents. These dietary plants had higher nitrogen contents than those non-dietary plants of the corresponding plant category, which were present in the study site but never found in the stomach contents. Individual grass species of high occurrence in the stomach contents were molasses grass, Melinus minutiflora, green couch, Cynodon dactylon and sedges, Cyperus spp. Although more fibrous, these species had similar or relatively high nitrogen levels compared to native shrubs, except during summer. This suggests that W. bicolor selected dietary plants of high nitrogen content rather than of low fibre content.
