I am not sure that NCAT will order the OC to pay anything. It will probably order them to fix the issue then may impose a penalty if it doesn’t. I have a feeling that once liability is established, you have to go to a district court to have payment orders issued. However, failure to fix common prperty is one of the possible triggers for the appointment of a statutory manager and maybe you could threaten the SC with that – and it doesn’t even require mediation in advance.
