Sounds like NSW could do with the ACT’s ‘reduced quorum’ concept!
Here a quorum is 50% with much the same caveats about being financial etc. However, a much smaller number can decide to proceed with a meeting after half an hour if there is not yet a quorum. Then any decisions do not become effective for 28 days and the decisions must be notified to all owners within 7 days with prescribed notice of reduced quorum decisions form. The decisions can be overturned by a new general meeting or by a petition of 50% of owners.
All that means you can get on with the general meeting without a quorum but there are safeguards against a poorly attended meeting making crazy decisions.
