jpaoloni, the Owners Corporation has to repair common property regardless of any other considerations, such as defect claims. In many ways, they may be able to progress the defect claim by showing they chose the best or least expensive repair option. If they refuse to do anything until the defect claim is resolved, you can take them to NCAT for orders under Section 62 of the Act. Explain that you are prepared to do that and they may get moving on this.
