Communities in the Murray Darling Basin have spent the weekend trying to digest the details of their future and they don't like what they see.

The Nationals Senator for New South Wales John Williams says the guide to the MDB Plan has already outraged the farming community and business leaders in the north and north west and the only saving grace is there remains plenty of consultation and work to do.

Senator Williams said the Gwydir Valley Irrigators Association which is based at Moree believes job losses will be in their thousands and food prices will have to increase.

"The Association estimates that if a 37 percent reduction in water diversions is to be achieved in the Gwydir Valley, the Government would need to buyback 318,000 of the 509,000 megalitres of general security licensing.

Those are stark figures and are likely to be repeated across the Basin, resulting in a devastating effect on communities that depend on their farming sector to survive.

A loss of a farm job has a concertina effect on the local machinery dealer, newsagent, clothing store, hotel and so on.

Deniliquin in the south of the State has already taken a hit this year with the closure of the red gum forest to logging. Now the communities in the region are being told there is more bad news to come.

I urge people to attend a consultation meeting to air their views and leave the Labor-Greens alliance in no doubt they will fight for their future", Senator Williams said.
