Australian Environment Minister Peter Garrett has given the green light for the establishment of a massive uranium project in South Australia, according to local reports.

Garrett, who has previously opposed nuclear energy and uranium mining, has given environmental clearance for the Four Mile mine, hailed as one of the most significant uranium finds in 25 years.

Garrett said the government approved the mine after a comprehensive assessment process found it would pose no credible risk to the environment.

Prime Minister Kevin Rudd said renewable energy and cleaner coal technology would enable Australia to tackle climate change effectively, according to the Sydney Morning Herald.

Australian environmental groups have opposed the mine claiming the chemical and radioactive waste would contaminate nearby groundwater.

The mine is expected to create about 130 jobs.
