Part of my job qualifications were met observer hence my interest. Now in Brisbane but lived in all states except WA.
So, Mal, I suspect you might have met Chris Bain and Evan Lee?

Cheers, Rowan

Good detective work Rowan but now you will have me puzzling all day. Evan Lee doesn't ring a bell but Chris Bain definitely does. For the life of me I can't think where from. It would be an aviation link if it's the same person.
