He was a Shooters, Fishers and Farmers Party member of the New South Wales Legislative Council from 2006, when he filled a casual vacancy sparked by the retirement of long-time party leader John Tingle, until 2019, when he was defeated for preselection by Mark Banasiak.
He left school in 1966 at the age of 15 to take an apprenticeship as a fitter and turner at the Cockatoo Island Dockyard, rising to become plant superintendent.
Brown left the dockyard in 1978 to take up a management position with a subsidiary of Lend Lease, and remained with the group when it was sold to James Hardie Industries in 1985.
