Liberal member for Goulburn Pru Goward said today the Liberal-Nationals would vote against the Iemma Labor Government's proposal.

"Morris Iemma's proposed sell-off fails the public interest test," Ms Goward said.

"Government's only get one opportunity to sell a public asset and, if they decide to sell, it's essential that taxpayers get the best possible price.

"That's not possible given the current uncertainty in the energy sector."
