have noticed a few times flying into Canberra that the T-VASIS can indicate a 1 dot high approach and the other side show a 1 dot low at the same time. I now make that the challenge to see if I can keep both all the way down the approach.

If and when you see conflicting information such as PAPI perceived erroneous indications or navigation aid anomalies, it is best you advise ATC or if no ATC then a report into the Air Services reporting system. Otherwise no one knows about the defect and nothing gets fixed. The problem is pilots are often shy or reluctant to say something officially lest nothing is found to be wrong and they feel a fool for opening their mouth in the first place.
