CommentSynonymy: after TTWG 2012.

Habitat: freshwater (rivers, swamps)

Genetics: Chelodina expansa has no known mitochondria of it's own, having that of C. longicollis or C. canni I depending on locality and sympatry. These species are in different subgenera as an aside. C. canni and C. longicollis hybridize in one river at an overlap zone but no where else. C. rugosa has hybrids with both C. burrungandjii and C. canni, including 3 way hybrids (is F1 hybrids breed with a 3rd species). (Scott Thompson, on Taxacom, 28 May 2024)

Distribution: see map in Kehlmaier et al. 2025: 128 (Fig. 1). 
EtymologyNamed after John Cann of Sydney, Australia, for his contributions to turtle biology.
