Yes the document mentions that Darling Downs Zoo would like to import two unrelated pairs of Bat-eared Fox to begin with. Apparently there are three zoos interested with both the Silvery Marmosets and the Red-bellied Tamarins.
They should have five to six species of callitrichids at the moment - Common Marmoset, Golden Lion Tamarin, Red-handed Tamarin, Emperor Tamarin and Cotton-top Tamarin. I am not 100% about whether they still have Pygmy Marmoset - they haven't been on-display for quite some time (of course that doesn't necessarily they don't still have them). If they do still have the pygmys then that would be the complete set available in the region currently.
Wildlife HQ (emperor, cotton-top, golden lion, common and pygmy), Halls Gap (same range of species as Wildlife HQ), Perth Zoo (same combination of species as Wildlife HQ and Halls Gap) and Hunter Valley Zoo (emperor, cotton-top, red-handed, common and pygmy) all have five species.
