NSW Can a decision by another tribunal or court in Australia be used as evidence at NCAT?

[Ajason]

I received a contrary decision on a particular matter at a tribunal which relied on false and incorrect information. That decision and the reasons for that decision are now partly being used by an applicant in another and completely separate tribunal as their evidence and to support their claim (which is equally false and incorrect). Basically my life is being destroyed and rights taken away due to reliance on a number of small and untrue events.
