LEGISLATION that paves the way for a nuclear waste dump in the Territory is "anti-democratic" and should be immediately scrapped, activists say.

Their views will be heard by a Senate committee which will hold public hearings on Monday and Tuesday at Alice Springs on the future of the Commonwealth Radioactive Waste Management Act.

The controversial law was passed by the Howard Government, which had short-listed Harts Range, Fishers Ridge and Mount Everard.

Muckaty Station, 120km north of Tennant Creek, is now also on the list after being nominated by the Northern Land Council.

In September this year, the Greens introduced a Bill into the Senate which would overturn the 2005 act.

Federal Labor made an election promise to repeal the laws but has yet to do so.

"The ALP made a clear commitment they would respond to the strong opposition expressed by the majority of Territorians, the NT Government and people from affected communities," Natalie Wasley from the Beyond Nuclear Initiative said. "It is time for them to fulfil that."

She said a public rally would be held at Alice to coincide with the hearings.

"The hearings are an opportunity for the Senate committee to hear directly what the different stakeholder groups are saying," she said.

Mitch, an Arrente-Luritja woman seeking to protect the Harts Range site, said the hearings would allow governments to "hear the voices".
