So far, I've just watched episode 433 with the commentary being provided by Tina Bursill (Sonia Stevens) and Michael Idato.
I hadn't realised that Stan Dobson (Brian James) and Rick Manning (Andy Anderson) appeared so early on in the series. I had thought that they arrived at the back end of the 1984 season.
Also, interesting to learn that the actors and the snake were NEVER on set at the SAME time
