Fourth of July celebrations at Woomera.

Tracking and communications stations near Woomera were involved in the USA's Mercury and Gemini space programs, and the Moon landing mission. However it was the establishment of the Joint Defence Facility Nurrungar (15km south of Woomera) in 1969 that led to an influx of personnel from the US. The Fourth of July was a day of fun and celebration for both Americans and Australians.

When Nurrungar closed in 1999, of a total Woomera population of about 1200, around 500 were United States Air Force personnel and their families.
