The Liberal Party may have made valid criticisms of the Federal Government's lack of action on the Murray-Darling and other issues, but neither of the major parties have proven their credentials on the environment, according to the Australian Greens.
Senator Sarah Hanson-Young, Greens spokesperson on the Lower Murray, says last night's speech by Tony Abbott has attracted a lot of attention, but that the Liberals have to do more than just talk to convince people they are serious on the environment.
"Tony Abbott's proposals have some merit, but so far there is no reason for the Australian public to believe him on the environment,'' Senator Hanson-Young said.
"For a man who says he favours practical environmentalism, Mr Abbott has practically no credibility on this issue.
"Just like the Federal Government, the Liberals have an embarrassing track record of failing to commit to ending old growth logging, launching international action on whaling or setting ambitious greenhouse targets - the environment deserves better from our leaders.''
The Greens have already called for a Commonwealth takeover of the Murray-Darling Basin, but Senator Hanson-Young said any such move must not simply replace one set of problems with another.
"A national approach to the Murray-Darling is the right move, but let's take the decisions away from bickering politicians - and not just State Premiers,'' Senator Hanson-Young said.
"Let's give an independent authority that isn't driven by polls or elections the powers to do what needs to be done and override damaging state vetos.
"We can't wait for a referendum in 2013, or the Government's plan which won't be complete until 2019. We need action now, and our leaders need to show they are up for the fight to save the Murray-Darling.
"Tony Abbott has a long way to go to convince people that the Liberal Party will not simply repeat the failures of the Rudd Government to tackle the big environmental issues.''
