I tried a google search of “industry standard strata levy” and found nothing. My previous two strata managers had processes which were not as lengthy as yours. They were similar to the process outlined in Strata Schemes Management Act 2015 (NSW) Section 86 “Recovery of unpaid contributions and interest”.
Remember: the owners are in charge of the strata plan, NOT the strata manager. We were told at an NCAT hearing that the owners corporation is ultimately responsible for everything that goes on with the strata plan. The owners corporation delegates its responsibilities eg levy collection to the strata manager. If the owners corporation wants something done differently, the strata manager has to listen.
As an individual owner, you are not the whole owners corporation. You will need the support of other owners. Try talking to the other owners, specifically the ones who actually pay their levies. You need to find out who would vote with you to change the overdue levy collection rules.
If you get 50% of the owners to draft a new set of rules for levy collection, call an extraordinary general meeting. You don’t have to involve the strata manager in this. In my strata plan, we followed the rules as outlined in the Strata Schemes Management Act and called a meeting to change some things we didn’t like about our strata manager (excessive repair costs, unnecessary tax returns).
It is possible that your strata manager will be very unhappy if you do this. Just remember that the strata manager is your slave, not the other way around.
