Amendment to Levies at AGM

I just read on line that an amendment can be moved to adjust levies down by 10 per cent at an AGM and if voted on only the votes of those present would count ie the proxy for an absent owner would not count. 

This article was written for QLD but interested if it applied in NSW. 

Also query what happens when the current levy proposed is totally rejected at the AGM. Is the OC able to continue to operate with the existing levies or does it bring everything to a standstill so no invoices etc can be paid??
