Earlier this month, a discussion paper detailing how 17 LHNs will replace the current eight area health services was released, with submissions accepted until September 1.

According to the paper, the aim of the shake-up is to "decentralise public hospital management and increase local decision making".

But Griffith City Council's general manager Peter Brooks cites a lack of transparency as cause for concern.

"One of the problems has been that when you look at what they have put out it doesn't give much detail," he said.

In April, council sent a submission to NSW Premier Kristina Keneally outlining some of their concerns and suggestions in regards to health in Griffith.

They were hopeful some of their ideas would be taken on board before any final decisions were made.

However, an advertisement calling for expressions of interest for chairpersons for the local health network governing councils, which appeared in Friday's The Area News, has left Mr Brooks wary.

"In relation to that ad, I think it demonstrates that NSW Health - in particular Greater Southern (Area Health Service), haven't consulted properly at all," he said.

"Submissions haven't even closed yet, but it seems they have already made up their mind. They are obviously not being transparent."

Some of the other communities joining Griffith in the proposed Murrumbidgee LHN are Balranald, Batlow, Berrigan, Cootamundra, Deniliquin, Finley, Gundagai, Hay, Henty, Hillston, Murrumburrah-Harden, Wagga, Wentworth and West Wyalong.

Mr Brooks said it was "ludicrous" to throw Griffith in with centres located as far away as Wentworth near Mildura.

"The query that needs to be asked is where is the local in that," he said.

"My real concern is that what's been proposed is actually a larger area than what we currently have.
