WIN shuts Mildura, Mackay newsrooms

The WIN television network is shutting local newsrooms in Mildura and Mackay.

Newsroom staff have been told they will be redeployed within the network, but the closures are due to problems with commercial viability.

The final local bulletins in Mildura and Mackay will air on Friday.

WIN Network CEO Andrew Lancaster said it was a tough decision for the company but the current economies of the media sector demanded a change.

"As regional Australia's most prolific producer of local news bulletins, WIN remains committed to local news across the majority of our markets," he said in a statement on Friday.

"But in a media environment that has its challenges and is faced with constantly increasing program supply and infrastructure costs as well as a lack of regulatory reform, we need to continue to review our operating model to ensure the ongoing success of WIN as a business."

The Facebook pages of the regional Victorian and Queensland stations, which each had thousands of fans, have already been shut down, while Twitter accounts for both have been locked.
