Cobra – as Jimmy has stated Cl 63(4) is not as definitive as the ACT’s provision, and for that reason I don’t think that it’s a worthwhile try-on in your situation where it’s Owners individually and not the Owners Corporation collectively who’s responsible for providing access to the Lots, and where an activity such as that is not really “work” under any reasonable interpretation.
Whilst I agree with your logic, an Owners Corporation can’t pass-on a third party’s re-inspection / no access fee by adding it to Owners’ levies, but it certainly can as I think Jimmy’s suggesting add it to their levy contributions invoice as an additional line item, which can’t in my opinion have the permitted interest applied (because it’s not a levy contribution) will, if unpaid, remain as a debt against the Lot that will eventually be recovered (even at the time of a sale).
We’ve had similar problems, and have found that additional fees such as the ones you mention are more readily paid when the charge appears on Owners’ next levy contributions invoice as opposed to on a separate piece of paper.
