Rum Jungle is an old uranium mining region around 100km south of Darwin. According to Wikipedia, "the area derives its name from an incident when a thief stole 750 ounces of gold from miners after getting them drunk with rum". Another story is that the local pub ran out of all drinks except rum and everyone in town had to drink rum.
After the Rum Jungle uranium mine was closed in 1971, attempts have been made to clean up the site and the radiation. The mine is now known as one of Australia's most radioactive and polluted areas.
