He was a Liberal Party member of the Legislative Assembly of Queensland from May 1976 until his sudden death in May 1977.
Brown was a member of the Liberal Party's state executive and the party's chairman in the federal seat of Lilley from 1973 to 1975, and was campaign director for a number of local, state and federal election campaigns.
[1] He entered the Legislative Assembly in a heavily contested 1976 by-election for the seat of Clayfield, following the retirement of John Murray.
Clayfield was normally a safe Liberal seat, but with growing internal tensions in the conservative coalition, Brown faced a concerted challenge from the National Party, who nominated their high-profile state secretary, Mike Evans.
A second by-election was not held due to the proximity of the 1977 state election, when the Clayfield seat was abolished in a redistribution.
