It seems that all cases in Austlii from the basic level of NCAT have been removed from the internet. Strange!
However, there are a couple of appeals against decisions, all of which originally resulted in the complaints against committee members being refused.

It’s worth noting again that in all the cases I could find, they were appeals related to some aspect of a case in which an application to remove some or all members of a committee had failed.
There were no appeals listed where committee members were appealing against their removal.
Make of that what you will.
