Here is a highlights package that Seven showed of its coverage of the 2002 Manchester Commonwealth Games. Notice Basil Zempilas in commentary in the diving.
It would also appear that Johanna Griggs anchored the studio coverage from Melbourne, as you can see from the Sportsworld website that was on the desk.
Similarly, Seven would also show a highlights package of the 2018 Gold Coast Commonwealth Games a week after the event finished. It (as well as the Opening Ceremony) was available on 7Plus as recently as April last year, just as the country entered lockdown.
A little bit misleading as the ABC relay station ABKT11 had been on air since January 1972. But yes, TNT9 didn’t commence there until September 1988 (TNT8)
(edit: The report did specifically mention commercial television)
Presumably nowadays, King Island receives the full array of television services which residents of the Tasmanian mainland (for the want of a better term) can receive?
A while ago, I found a promo DVD from when the ABC were preparing for their controversial 2008 rebrand, which I believe was issued with one of the ABC’s magazines. I have recently ripped it onto my Internet Archive cause this may be of interest to other people.
