Hi everybody - Peter Menkhorst said:"The usual explanation is that the savannah grasslands of the Victorian Volcanic Plain were a barrier to movement of these missing species [except the Wombat]. The Volcanic Plain extends to the sea in the Werribee-Avalon region and on the Bellarine Peninsula preventing forest-dependent species with little dispersal capability from crossing. " And maybe the (or some) missing species used to be there before the peak of the last ice-age, but were squeezed out of shrinking habitats and never recolonised. Though I seem to remember some argument a while ago about anecdotal evidence of lyrebirds there.
