Wollongong is a sea-side city about 80km south of Sydney. I lived there in the 1970s, and my parents came from that area.
That last one is strange. I hadn’t realised when taking it, and I didn’t speak to the man as I just snapped him almost in reflex, but I swear he is an old colleague from the 1970s! I have emailed a copy to a friend who also knows him. If I am right, what a missed opportunity. (He’s not listed in the phone book.)
