WA Greens Senator Scott Ludlam has urged the state and federal governments to take note of the decision by the Northern Territory government to oppose a uranium mine proposal near Alice Springs.
Cameco is leading the push to explore the site, which is about 20 kilometres from the town.
Northern Territory chief minister Paul Henderson said there was strong community opposition to the mine.
He told the ABC Labor is listening to the concerns but the decision does not mean the NT government is opposed to new uranium mines elsewhere in the Territory.
Senator Ludlam said the Greens were delighted the NT government has rejected the plan.
The federal government will decide if the mine goes ahead, and Senator Ludlam has urged Resources Minister Martin Ferguson to support the decision by Mr Henderson.
Cameco also wants to open a uranium mine at Kintyre in the East Pilbara.
"Understandably the Martu people of the East Pilbara have expressed concern about likely impacts on local hydrology and their health," said Senator Ludlam.
"I urge Cameco and the WA government to take note of the strength of community feeling in the Territory.
"There are many Western Australians who are also concerned about the proposal to allow uranium mining in WA.
"Any uranium mine proposal for Western Australia will also experience strong opposition," he said.
