Anti-nuclear campaigners say they are pleased a Senate inquiry into a Northern Territory nuclear waste dump is coming to Alice Springs.

The Senate's environment committee is investigating the possible repeal of the Howard government legislation that overrode NT laws against a dump.

It will hold public hearings in Alice Springs next Monday and Tuesday.

Natalie Wasley from the Beyond Nuclear Initiative says she hopes many central Australians will attend.

"This is the opportunity for them to hear what the different stakeholder groups are saying and to have a public presence there to show the committee that this issue hasn't gone away after three years," she said.

"People are still very engaged and very strong in their opposition and are looking forward to an outcome in favour of the view of the majority of Territorians, the people at affected communities and the Territory Government."
