I know nothing of this particular incident. However, I was based at MPA for 4 months in the first half of 1988 and visited Alice/Byron/Kent on a number of occasions as part of the 78 Sqn task - I could fully believe the antics as described. For sure, excessive alcohol consumption had a part to play in numerous occurrences.
Vague recollection - Alice was the only site where female scopies were sent with Byron and Mount Kent being male only.
