Radio stations 2GB, 3AW, 4BC, and 6PR will ramp up local content with new traffic reports every 10 minutes in the key Breakfast and Drive shifts.
The move is part of Nine Radio’s strategy of “live and local”.
Nine Radio’s head of content, Greg Byrnes, said: “Nine Radio is the only radio network with local traffic reporters in each market, with deep knowledge of their city’s traffic and accident blackspots, offering the best advice during the commuter rush about how to avoid any traffic snarls. As our biggest cities roar back to life, our listeners will now be getting updates every 10 minutes.”
