Energy Resources of Australia (ERA) is the world's third largest uranium producer and Australia's largest, supplying eight per cent of western world demand. ERA operates the Ranger mine 260 kilometres east of Darwin in the Northern Territory. The Ranger mine is located in an area adjacent to the World Heritage listed Kakadu National Park, and especially stringent environmental requirements apply. Activities at the mine are overseen by Territory and Federal Government supervising authorities. ERA supplies uranium to base load electricity utilities in Japan, Korea, Europe and North America. All Australian produced uranium is designated for non-weapons purposes and its trade and subsequent use is monitored by Australian government and international agencies. ERA employs approximately 260 people with 20 per cent of the operational workforce represented by Aboriginal people.
