The South Australian town of Coober Pedy is known for its opal mines, producing about 70 percent of the world’s opals. Celebrated over Easter weekend, the annual Opal Festival includes such competitive events as the mine rescue demonstration, tug-of-war, triathlons for men and women, games and races for children, and the multicultural dance and singing competition. Saturday is the main day, kicking off with a morning street parade featuring a marching band, mining equipment, and floats and culminating in a fireworks display and a dance at night. Discuss
