Chris Mo'ane is 100 percent right on this. The OC caused the damage and/or their repairs damaged your paintwork. Therefore they need to pay for the repaint job. Time your strata manager and CTTT connections got themselves up to date with the law. This is a misconception that's as common as it's wrong. Chris, by the way, is a recent Strata Business Person of the year. His company Integrated Building Consultants (ibc.com.au) are pretty much leaders in their field.
