Holbrook Shire was proclaimed on 7 March 1906 as Germanton Shire, one of 134 shires created after the passing of the Local Government (Shires) Act 1905.[1] The shire was renamed Holbrook Shire on 6 August 1915.[2] The renaming was a demonstration of patriotism during World War I and the name was taken in honour of Norman Douglas Holbrook, a British submarine captain awarded the Victoria Cross earlier in the war.[3]
