StG: 20. (I am guessing is John Conway see 0:03, you can see his face at 0:24)
Newt: 15. Bill Grech (see 0:30 + 1:12 + scoring at 2:22), 22. (see 1:50), 21. ?? (see 2:35 Col Murphy?), 22. ?? (see 3:15)
Are you sure that 1. is PHIL Sigsworth & not RON? Ron is named in BL & Canberra Times dd 28/8/81 & he looks like Ron to me.
