As a
fitter, Brooker was a member of the Australian branch of the
Amalgamated Engineering Union, and joined the
Labor Party, unsuccessfully running for the electorate of
Franklin in the
Tasmanian House of Assembly. Inspired by
Major C. H. Douglas'
Social Credit movement, Brooker ran for Franklin again in 1934 and won, becoming an MHA on 9 June 1934. In December 1947, the
Premier Robert Cosgrove was
indicted on charges of bribery and corruption. Cosgrove stood down as Premier during his trial, and Brooker was sworn in as his replacement on 19 December 1947. The trial was concluded by February the next year, and the charges against Cosgrove were dropped. Brooker stood down after only two months as Premier, and Cosgrove was reinstated, appointing Brooker as Treasurer and Minister for Transport. Four months after resigning the Premiership, Brooker died at his home in
Montrose after suffering a
pulmonary oedema on 18 June 1948. ==Legacy==
