Recent molecular analyses suggest that the position of bandicoots is the major difficulty in determining the root of the tree of extant marsupials. To resolve this, we analyse mitochondrial genome sequences of a bandicoot (Isoodon macrourus) and a brushtail possum (trichosurus vulpecula) together with the wallaroo (Macropus robustus). Analyses of mitochondrial protein-coding and RNA genes strongly support the bandicoot as sister to the wallaroo and the brushtail possum. This result, combined with other recent molecular analyses, confirms the monophyly of Australidelphia (Australasian marsupials plus Dromiciops from South America). Further, RY coding was found to nullify AGCT coding nucleotide composition bias.
