A bit nasty, but legal in NSW at least. In effect you’re short paying each levy by $2.30, which bobs up on the next bill for the following quarter. So you are in arrears by that amount each time. If you pay an extra $2.30 for a quarter then you should be OK and thus financial. Interestingly, there is no requirement for a Strata Manager to send out levy notices in the Strata Schemes Management Act, you’re supposed to pay in full and on time when the levy is due. Of course if they didn’t do so, a lot of owners would “forget” and there would eventually a lot more arrears to chase, and more interest incurred.
