In Vic we can keep legally obtained animals of the following:
Delma australis, Delma inornata, Western and Eastern Hooded Scaley-foots, Burton's and Common Scaley-foots.
I'd recommend either of the scaley foot species as they have very similar husbandry needs to geckoes like knob-tails, so they're very easy to maintain in captivity.
Burtons have a specialized diet (skinks and geckoes) so I wouldn't recommend them unless you have a ready supply of small lizards, or are confident in assist feeding pinkies.
