I would check the Act in the relevant state. I would expect from ACT experience that any EC member can call a meeting with 7 days notice. In your case I would guess that 2 members would be a quorum of the EC so you could not make decisions on your own. I think some small owners corporations make each meeting a general meeting which enlarges the range of decisions you can make. However, I expect that the acts in various states would require greater notice for a general meeting and notice of the motions to be put. In the ACT a petition of 25% of members can require the EC to call a general meeting. If you have a similar provision you could call a general meeting.
