The wiki at https://wikimedia.org.au/noongarwp/ got attacked by spambots. It's since been made read-only, but the spam still needs to be purged.

Basically every edit since 1 Sep 2015 can be deleted with confidence, looking at the histories of the key users the last edit any of us did was 25 August I doubt there will be anything of importance lost with such a move and it'll probably be before the spam bots found us

The wiki will then stay as read-only, and be moved to https://nys.wikimedia.org.au .
