NBN covers hundreds of kilometers in the Hunter and Northern Rivers and has a population reach of about 1 million. 7GC covers 100 or so kilometers that is duplicative of its parent market and has a reach of 600,000 or so.
Lest we suggest that 7 start covering what’s in Prime territory to justify investment in the GC operation, I’d call it a tough sell to invest in separate controls and a few more reporters and producers to make a composite broadcast.
Heaven forbid ACMA slice away Gold Coast to make it its own market.
