I think you're right: Tim Kava was the only Wallaby to emerge from CAS & the Waverley 1979 Premiership winning team.
However, Andrew Ugarte (Waverley) & Toby Jones (Cranbrook) made the Aussie Schoolboys team in that year.
CAS Aussie Schoolboys in 1978 were: Phillip Tuck & Robert Davis (Knox) & Michael Maxwell (Cranbrook)
And of course, the only Wallaby to emerge from the GPS in 1979 was playing in the 2nd XV for Newington. In fact, as far as I remember, the only other future Waratah in GPS that year was in the Scots 2nds (David Croft).
