That café conversation SA-TV recounted makes me think Prime might be looking at doing away with the separate local and national bulletins and following SCA Nine by producing a composite one hour bulletin.
I'm not aware of Prime advertising for additional news staff in Canberra recently so perhaps they aren't quite ready to re-establish local news in the areas they abandoned years ago. It would be a good use of existing resources, however, for them to do a one hour bulletin with local windows in areas where they have traditionally maintained a full local service.
It wouldn't be the first time Prime attempted a one hour bulletin covering local and national news. They tried and failed back in 1993 when they attempted to take on WIN and Capital in Canberra by raiding talent from the market leader, Capital.
Prime could look at re-entering the local news battle in Canberra, Wollongong and Newcastle with the composite bulletin once the one hour format is bedded down in the markets they already service. It makes sense for them to have another go now that Prime7 is the number one network across most of regional Australia.
