MUCKATY Station is this week expected to be named as the site for the controversial nuclear waste dump.

The revelation follows a series of secret meetings Federal Resources Minister Martin Ferguson held with the Northern Land Council, and separately with NT Chief Minister Paul Henderson and Resources Minister Kon Vatskalis.

Beyond Nuclear Initiative campaigner Natalie Wasley said a decision wasn't expected before Wednesday as Federal Government caucus meets on Tuesday and the decision would need to be ticked off.

Solomon MHR Damian Hale said he would be prepared to lodge a private members motion that Territorians do not support the proposed nuclear waste dump being placed in the NT.

"We are getting to the pointy end of the debate this week," he said.

"We are going to fight tooth and nail not to have the nuclear waste dump here in the Northern Territory.

"I don't think we have been treated fairly in this process. Territorians have not been given a fair go."

Minister Ferguson's spokesman Michael Bradley said the Government had committed to repeal the Commonwealth Radioactive Waste Management Act 2005 and would do so this week.

When asked repeatedly if the Government would make an announcement about Muckaty being the chosen site this week, Mr Bradley repeated the line about repealing the previous legislation.

Mr Bradley would not confirm the Minister visited the Territory, nor that he met with the Government and NLC - which has been brokering the deal with some traditional owners in the area.

Both the Territory Government and the NLC confirmed they met with Minister Ferguson during the week - neither would elaborate on the subject of the meetings.

Mr Hale said he would vote to support repealing the Howard legislation, but would abstain from supporting the expected announcement of Muckaty.

Ms Wasley commended Mr Hale's opposition to the Federal Government's processes.

"Minister Martin Ferguson has delayed the announcement for many years, refusing to meet with traditional owners for target areas and compounding the worry and stress for the affected communities," she said.
