NORTHERN Land Council chief executive Kim Hill has not met with traditional owners of the area earmarked for Australia's first nuclear waste dump.

The Gillard Government plans a dump site for low-level nuclear waste, most of which will stem from nuclear medicine, at Muckaty Station, near Tennant Creek in the Northern Territory.

Australian Greens senator Scott Ludlam asked Mr Hill and the council's principal legal officer, Ron Levy, in a Senate estimates hearing last week if either of them had visited Tennant Creek or the surrounding areas to discuss the dump.

Mr Levy said he visited at the time the Muckaty Station site was nominated in 2007.

Mr Hill, who has been in his role for the past three years, said he had visited the region to talk about other NLC issues but not the waste dump specifically.

"We do have a presence in that region and there is always an opportunity for traditional owners to talk about and consult with my officers regarding all matters ... under the Aboriginal Land Rights Act," he said.

Senator Ludlam asked Mr Hill what people had to do to get a meeting with him at Muckaty.

"I believe that we've done what we are required to do under the Aboriginal Land Rights Act," he replied. "The forums you're referring to in Tennant Creek, we don't necessarily believe that it's our responsibility.
