ARN sources have confirmed to radioinfo the news that everyone was expecting, the expansion of the KIIS brand.
It is expected that an announcement will be made imminently confirming that Mix 101.1 Mebourne will be rebranded with the KIIS llivery.
It is expected that the rest of the network will eventually follow suit, but not known if it will happen all at once.
UPDATE: Full details just released, see our updated report here.
ARN has stations in Sydney, Melbourne, Brisbane, Adelaide and Canberra, but not Perth.
Mix Adelaide is on top of the ratings, while Mix Melbourne is in eighth place.
The expansion will bring the momentum of the revitalised Sydney station 106.5 to the rest of the network and make it easier for ARN to sell a national brand to advertisers.
Other rumoured changes will also take place as part of the change, with Rosso leaving the network to make way for Dave Hughes and Kate Langbroeke on a national drive show.
