Labor Senator Trish Crossin missed a crucial vote to repeal the Commonwealth Radioactive Waste Management Act today because she was on Darwin radio sledging the Senator Nigel Scullion for missing a vote in the Senate yesterday.

The vote was to repeal the Commonwealth Radioactive Waste Management Act 2005 and introduce replacement legislation as outlined in Australian Labor Party policy.

Country Liberal Senator for the Northern Territory, Nigel Scullion said he was amazed that Senator Crossin was backflipping for a second time on an election promise.

"Trish had a chance to support The Greens on this in September last year and she hid somewhere to avoid supporting it, perhaps in a stairwell”, said Senator Scullion.

"Trish tore up a copy of the Territory’s Self-Government Act in December 2005 in protest over the introduction of the act and swore to fight to repeal the Act any chance she got."

"She has now had at least two chances to be true to her word and she has run away and missed the vote – again”, said Senator Scullion.

Senator Scullion said he apologised immediately and publicly yesterday for not hearing the bells in time to vote on an important matter and hopes his fellow Territory Senator would be honourable enough to do the same.

“Trish needs to apologise and explain why the vote was not important enough for her to be there”, said Senator Scullion.

“She was on radio this morning saying I was “off the program” and showing “a lack of leadership”, may I now suggest that it is Trish Crossin who is off the program and showing no leadership whatsoever on a matter she made an election promise and has subsequently made a very public song and dance about on several occasions”, said Senator Scullion.

“If she is a woman who practices what she preaches then she will be back on air apologising and explaining why she no longer supports the Labor policy on Radioactive Waste immediately”, said Senator Scullion.
