Crystal Brook, South Australia

Crystal Brook is a town in South Australia, named after the spring-fed creek next to which it was founded. It is 197 km north of Adelaide and in 2006 had a population of 1,185.

Crystal Brook is situated on Goyder's Line near the border of two climate systems. While apparently cold semi-arid, the town benefits from a temperate mediterranean climate zone near to the east, making possible slightly more intense farming in the region. To the west and north-west lies some marginal, semi-arid farmland. The local farming community is still able to support many small businesses in the town.

Crystal Brook (or creek) supplied water to the town until 1890 when the Beetaloo Reservoir was completed, which at the time was the largest concrete dam in the southern hemisphere.

The Sydney–Perth and the Adelaide–Darwin railways meet in Crystal Brook at a triangular junction.

Close to the north-south midpoint of the trail, Crystal Brook marks a change in climate. Hot, dry summers and mild winters lie to the north, and more temperate conditions to the south.

Broadband
Broadband became available at Crystal Brook on 16 April 2005 after lobbying from residents. Limited fibre backhaul capacity has resulted in Telstra limiting subscriber speeds to ADSL 1 speeds.
