Андамука: История и современность опалового городка.

A number of historic buildings in the town are heritage listed: the Andamooka Historic Precinct (containing Frank Albertoni's House, Bob Cutzow's Dugout, Tom Brady's Dugout, Mrs Perry's Kitchen and Andy Absalom's House) and Dick Clark's Residence are both listed on the South Australian Heritage Register.

There are numerous opal fields in Andamooka district, one of the principal outliers being White Dam. The original pick and shovel shaft miners, many of whom were the bush characters and social outcasts who gave the settlement a 'Wild West' reputation, were gradually displaced from the 1960s and 70s by the arrival of miners using bulldozers which made deep cuts to reach the respective opal levels, from where horizontal drives could easily be made to fully exploit the level. The several opal levels at Andamooka are not as deep as other fields such as Coober Pedy and Lightning Ridge. However, while the opal may be easier to reach, it is generally scarcer and poorer in quality. Those factors always made this gem field attractive to smaller prospectors with limited capital. Nevertheless, some remarkable gems have been mined, including the Andamooka Opal which was discovered in and named after Andamooka.

The earliest miners occupied rough dugouts driven into the side of a hill. The underground portions provided excellent insulation against the extremes of outside temperature. Being unsurveyed, occupancy was determined by tenuous Miners' Right. That situation deterred capital investment and so in the 1970s Andamooka was essentially a declining shanty town. Civic affairs, such as they were, were organised by a citizens' progress association. Their limited activities mainly related to electricity generation and supply, and maintaining the dirt airstrip in case the Flying Doctor was needed. All roads were unsealed tracks, while the main street was a dry rocky creek bed (unless there was a rare thunderstorm). There were few government agencies. Until a police station was opened in 1966, the police made routine weekly visits from Woomera, a mostly military town that supported the Woomera Test Range and Joint Defense Facility Nurrungar. Unless there was an emergency in between these visits, the isolated settlement was self policing. An establishment named the Tucker Box, which was a licensed restaurant, was the social hub. The Andamooka Co Op Ltd supplied groceries and fuel. In the 1980s, with an influx of work through the advent and development of the nearby mine at Olympic Dam, more houses were built and transported in. Many of the town's houses came from the demobilisation of Woomera. A transformation then took place. Not many people still live in the traditional dugout style houses of old, although remnants of the town's past remain in the main street, with the cottages of old miners dug into the side of the hill in the main street still standing.

In the , the town had a population of 262 people. There was a surplus of males (54.1%) over females (45.9%). Their median age was 57 years, nineteen years older than the national median of 38. Children under 15 made up 10.8% of the population, and people aged 65 years and over made up 31.3%. Aboriginal and Torres Strait Islander people made up 4.6% of the population. Most (75.2%) were born in Australia; the next most common countries of birth were England 6.1%, Austria 1.5%, Germany 1.5%, Croatia 1.5% and Italy 1.1%. The most common religious affiliation was "No Religion" 52.3%, followed by Catholic 17.6%, and non denominational Christian 4.6%. Until recently, Andamooka townsfolk had to rely on water supplies trucked in from Roxby Downs, or above ground cisterns for the limited rainfall of the region. A pipeline to the township has since been built, although water still has to be trucked to the town's water tanks.

The 1979 film The Last of the Knucklemen filmed its exterior shots in and around Andamooka. The "Andamooka Opal" was presented to Queen Elizabeth II on the occasion of her first visit to Australia in 1954. This opal, once cut, weighed in at
Andamooka was also referenced in the Max Brooks novel, World War Z.

Annual rainfall is extremely low, even by Australian standards, with the average in the region just 160 mm per year. The climate is very arid, with daytime temperatures in summer regularly topping 40 °C (104 °F) and night temperatures in winter often dropping close to zero (32 °F).
