Broken Hill is an inland mining city in the far west of outback New South Wales, Australia. It is near the border with South Australia on the crossing of the Barrier Highway (A32) and the Silver City Highway (B79), in the Barrier Range. It is 315 m (1,033 ft) above sea level, with a hot desert climate, and an average rainfall of 235 mm (9 in). The closest major city is Adelaide, the capital of South Australia, which is more than 500 km (311 mi) to the southwest and linked via route A32.
The town is prominent in Australia's mining, industrial relations and economic history after the discovery of silver ore led to the opening of various mines, thus establishing Broken Hill's recognition as a prosperous mining town well into the 1990s. Despite experiencing a slowing economic situation into the late 1990s and 2000s, Broken Hill itself was listed on the National Heritage List in 2015 and remains Australia's longest running mining town.
Broken Hill, historically considered one of Australia's boomtowns, has been referred to as "The Silver City", and less commonly as the "Oasis of the West", and the "Capital of the Outback". Although over 1,100 km (680 mi) west of Sydney and surrounded by semi-desert, the town has prominent park and garden displays and offers a number of attractions, such as the Living Desert Sculptures. The town has a high potential for solar power, given its extensive daylight hours of sunshine. The Broken Hill Solar Plant, which was completed in 2015, is one of the largest in the Southern Hemisphere.
