When Ch9 in Sydney started airing TNG, I seem to remember not long after, Ch7 started airing TOS again.
The Seven Network secured TOS rights when Nine let them lapse in the early 80s (not long before ST II arrived in cinemas). They launched it with a huge, free gala event at the majestic State Theatre, Sydney, and it was covered by the late TV news. In the background, as ASTREX club members were being interviewed, was the cinema marquee for "Clash of the Titans", which had been the current film at the State that month.
Seven ran most of the series weeknight in prime time, in production order, then it shifted the rest to weekends, and they repeated all 40 "G" episodes on the weekends, between tennis marches. Seven had the exclusive right to secure TNG for themselves, but they had to agree to a twelve-month video holdback, and they refused. Thus TNG passed to Nine, and Seven got cheeky by re-running some TOS.
Funnily enough, Aussies actually saw Diana Muldaur in "L.A. Law"
before we saw her on TV playing Pulaski!
