The Shingrix vaccination has been approved for use in Australia by the TGA and the TGA recommended it be included on the PBS. However, it is still not available on the PBS - medicare subsidised medications. You find the 2018 report of the PBS decision here:

The cost-benefit analysis seems to be the sticking point. Therefore, it is likely that the cost on a private script may be too much for those at risk to pay for a private script.
However, there is another vaccine available Zostavax that has been in use for many years and is free to those who qualify. This difference is that the Shingrix does not use live virus.
