The Australian Greens are concerned by yet another delay in releasing the draft report by the Murray Darling Basin Authority.

Australian Greens Senator Rachel Siewert has called on Woodside to better educate its workforce about respect for Aboriginal land after it emerged that contractors are driving across Aboriginal land in a bid to get around James Price Point protestors.

Greens MP Adam Bandt has backed a move by the Minister Tony Burke to further extend Commonwealth environmental controls over national parks, but warned it may not stop the Victorian government's plan for cattle grazing in the Alpine National Park.‪

Greens MP Adam Bandt warned that any move to list national parks may need agreement from state governments, which could take months or years, but that any attempt to reintroduce cattle into Victoria's Alpine National Park by the Baillieu government could be overruled by his bill before the Federal Parliament.‪‪

Mr Bandt said that if the Victorian government refused to participate in or sought to circumvent the Environment Minister's latest move, he would move ahead with a bill to comprehensively ban cattle from the park.‪‪

The Green's Environment and Biodiversity Conservation (Abolition of Alpine Grazing) Bill 2011 can be voted on in the next sitting of Parliament.‪‪

"The grazing season is only a couple of months away, so I am concerned the Minister's proposal may not be in time to stop the State government's plan to resume damage to the Alpine National Park," Mr Bandt said.‪‪

"Reintroduction of cattle into the beautiful Alpine National Park would be an act of environmental vandalism."‪‪

"The Premier can try any underhand methods that he likes but if my bill passes through Parliament it is game over."‪‪

"If the Victorian government tries to get around the Minister's restrictions, I would expect Labor to get behind a complete ban and support my bill."‪
