More than a hundred people have taken part in a protest against a proposed nuclear waste facility in the Northern Territory.

Muckaty Station, about 130 kilometres north, of Tennant Creek is the site being considered for Australia's first nuclear waste dump.

Protesters marched along Tennant Creek's main street, chanting "no dump at Muckaty, don't waste the Territory".

It has been five years since the site at Muckaty was first nominated for the facility but protesters say some of traditional owners of the land still have not been consulted about it.

Local MLA Gerry McCarthy stood alongside protesters and reaffirmed his commitment to fight against the dump.

He says he would take part in a blockade to stop construction of the facility, if it comes to that.

Diane Numbin Stokes is a traditional owner from Tennant Creek and a custodian of the land area that includes Muckaty station.

She says the land being set aside for the nuclear waste dump is an Aboriginal men's site, but this does not mean the women can't voice their concerns.

"We don't want the waste to come to that land," she said.

A Federal Court challenge against the nomination of the site is yet to be settled.
