ABC radio listeners will now be able to hear all five of the broadcaster's networks in Melbourne's Domain and Burnley Tunnels.The ABC has struck a long-awaited agreement with CityLink to broadcast in the tunnels, where reception was being lost.The ABC charter prevented the public broadcaster from entering into the same agreement as other commercial stations. CityLink's Brendan Bourke says a one-off payment has been arranged."There will be a payment from the ABC to pay for the equipment that's required to rebroadcast the signal and that will provide the service for the next 10 years," he said.
