I am hoping that this does not actually go to NCAT that mediation alone would sort it out.
Does the OP mean proceeding to a tribunal hearing? To obtain mediation in the first place, doesn’t a complainant have to lodge a complaint with NCAT, where the matter is first sent to mediation to resolve issues between the parties without a formal tribunal hearing? I am assuming that most complaints lodged are resolved at mediation level at NCAT because no-one, including the tribunal adjudicators want to hear and determine conflict matters that tie up court time and can be costly.
