Put a motion to the EC that owners, including EC members, must pay for damage they cause to common property themselves or through their insurance. Membership of the EC allows them no special privileges in this or any other regard.
Additionally, the EC should seek to recoup the monies paid in error to the specific EC member for fear that they be found to have acted fraudulently by giving special privileges or financial payments to EC members, the latter of which is specifically forbidden in strata law.
I would say there is an 80 percent chance they will refuse your motion, in which case you have grounds to take them to NCAT.
Or you could just point them in the direction of this post and tell them to look out for an upcoming Flat Chat column in the SMH.
