From my recent experience, NCAT seems to either treat the case as simple or complex.
I know in a complex case, it took about 3 weeks to get to the first hearing. This just sets up a timetable for the evidence. The to and fro of putting on evidence and rebuttal, was scheduled for 4 months. The other party discontinued the proceedings during this period, so I can’t provide commentary of how long it took to get to court.
My opinion is that it’s not a fast process ( as most court cases are). I think it’s entirely possible that in the process of putting on evidence the situation can change entirely.
One needs to be prepared for a long emotional process, so be sure you want to pursue your case.
