The story
It is thought by some that Darraweit Guim means “where three creeks meet” in a local Aboriginal language. Another legend has it that Darraweit means the meeting and Guim means the turn which the course of the water makes in the township. Which legend is correct no one is sure, but according to the Postal Department record of Post Offices in the Commonwealth of Australia, it is the only one known by that name. The first survey of the district was made in 1851 by Surveyor Foote, who gave it the name of Darraweit Guim, which was approved by the authorities in Sydney.
