Ten specimens including several dentaries and maxillae, recovered from the Pliocene Spring Park Local Fauna, northern Australia, are referred to the diprotodontine Euowenia grata (De Vis). The fossils exhibit minimal dental wear and reveal new characters that are unrecognizable in the holotype. The remains represent at least three animals, effectively doubling the previous number of individuals known for this rare megaherbivore. The new records also provide a significant northern geographic range extension for the species and allow an assessment of intraspecific variation, sexual dimorphism and phylogenetic relationships for the species. Euowenia grata is most similar in morphology to the monotypic Pliocene diprotodontid Meniscolophus mawsoni.
