I’m in Vic. I always thought it was almost discretionary for the strata manager to consider interest on overdue levies.
Not in NSW. There the 10 per cent late payment charge is mandatory but may be waived by an owners corp decision at a general meeting.
The question is, shouldn’t penalties apply from the last day of the 30 days’ grace given after the due date. And I would say yes, unless there are special rules for special levies (that I don’t know about).
