Don't you any have clips from the Brisbane news (Mike Higgins and Frank Warrick), as well as the Sydney ones? (the ATN-7 stuff is pretty hard-to-find from around that era)
weather presenter was Debbie Phin, and the main newsreader was Pamela Graham. I presume this was a Saturday night bulletin as Debbie was saying "that's all I have for you now until the Super 66 draw at 8.30".
