New legislation introduced in federal Parliament clears the way for the resolution of the Northern Territory's longest-running native title claim.
The bill formalises the handover of the Jabiru native title claim area, including the Jabiru township in Kakadu National Park, under the Aboriginal Land Rights Act.
It clears the way for Jabiru to be handed back to traditional owners under the Aboriginal Land Rights Act.
Amendments to the Act enable the transfer of ownership of the land from the Director of National Parks to the Kakadu Aboriginal Land Trust.
The Gundjeihmi Aboriginal Corporation represents the Mirrar traditional owners.
Executive officer Justin O'Brien says the legislation provides certainty to everyone with a stake in the region.
"Once the scheduling is done, once the Jabiru area is added to the Land Rights Act, negotiations can commence to issue a head lease over the town and, ultimately, withdraw the long-running native title claim over the town," he said.
Business operators have been worried about what would happen to the town when the head lease expired in 2021.
Mr O'Brien says the new law means traditional owners will drop their native title claim.
"This is an important step in providing a greater security of tenure for business, for government, for traditional owners, for industry in Jabiru," he said.
Meanwhile, Ranger uranium mine operator Energy Resources Australia (ERA) says it has agreed with traditional owners to introduce more detailed environmental monitoring at the site.
An independent review of surface water management has made 15 recommendations to expand monitoring of the mine site and the surrounding area in Kakadu National Park.
Mr O'Brien says the changes will give traditional owners access to a lot more information.
The township of Jabiru, about 280 kilometres south-east of Darwin, was first established to service the needs of the Ranger uranium mine and provide a site to accommodate workers.
The mine is situated within the World Heritage listed park's boundaries.
Earlier this year, ERA settled a 14-year battle for increased royalties to be paid to the Mirrar people.
