Millie – it’s awfully difficult for you to influence proceedings at an AGM when you couldn’t personally attend, but notwithstanding that and the foibles of the NCAT you would in my opinion make better progress there if you were to concentrate one-by-one the many items of low-hanging fruit that your posts have identified instead of going in boots-and-all for the statutory appointment of a Strata Manager.
As but one example, the Chair’s refusal to conduct a poll vote would be worth a challenge under Sect 153 particularly in circumstances where the result of the vote as taken likely produced a different outcome.
