While Qantas international pilots are trained in autoland procedures at some overseas airports, they are not approved for anything other than emergency use at Australian airports because none have ground based navigational aids that are certified as reliably generating signals of sufficient accuracy for such ultra low visibility landings.
This was not true even when it was written. I suspect what the author was trying to say was that there were no CAT II/III installations in Australia. Cat I autolands have always been approved at Australian airports for Qantas international pilots.
