Huh? Did the Aussie gun ban ban rifles with manual bolts that turn and move back? They were that specific to where a straight-pull bolt (like most ARs) is not under the ban?
They did not ban bolt actions, but they banned (or made extremely restrictive, almost the same thing) the licenses for semi-auto rifles.
A straight pull bolt, manually operated, is not a semi-auto, so it is not banned.
