Yes, it would be “old news”, recorded an hour earlier, but it would give most GC viewers the choice of watching the Brisbane/QLD news on TVQ or the Sydney/NSW bulletin on NRN/WIN.
What’s in it for WIN though by relaying Sydney news into the GC? If viewers switched over to TVQ for their “local” news, would they switch back? And I wouldn’t have thought Ten News Sydney would cover any GC stories unless they were of national significance. Surely it would divert viewers in the overlap area away from WIN.
