From the SMH article that was linked in the ‘ABC Operations’ thread:
Another key change is already under way: the reduction in local news stories in the 7pm state bulletins. Two media sources familiar with the plans said management had decided to reduce the number of state-based stories to a maximum of five per bulletin, with a greater emphasis on nationwide and international news.
An ABC spokesperson said the move is an attempt to allow the broadcaster to focus more on digital video while maintaining the quality of the bulletin.
