Crystal Brook is a town in South Australia,
named after the spring-fed creek next to which
it was founded.

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 still
supports many small businesses in the town.
