There is a time capsule at Richmond High School from the 1980’s, says Arthur Georgantas on FaceBook.
It was to be opened around this time and quite a few students contributed to this. It is worth investigating with the Melbourne Girls Secondary College. Its just outside the entrance of the office as you come in from the railway bridge side.
George Papairaklis says I remember the time capsule too, maybe 1983 or 84 and they said it will be opened in 50 years time (2033/34)!!! Its almost 30 years now!!! Wasn’t it in a plaque, outside the main entrance near the front office facing the boulevard end, on the lawn there???
Arthur later said, I did it, I climbed the fence and disappointed to see that our time capsule may noy be there.
