He was a Labor Party member of the New South Wales Legislative Assembly from 1927 to 1932, representing the electorate of Leichhardt.
Olde was born at Vittoria, near Bathurst, but was raised in Petersham in suburban Sydney, and educated at the Christian Brothers' school at Lewisham.
A clerk by profession, he worked alternately in the Railways refreshment rooms, as an estate agent, and in the office of the Labor Daily newspaper.
Olde was elected to parliament on his fourth attempt when, in 1927, he won the newly recreated safe Labor seat of Leichhardt.
Olde was succeeded in Leichhardt by Joe Lamaro, the recently defeated MLA for Petersham.
