A by-election was held for the New South Wales Legislative Assembly electorate of Vaucluse on 29 August 1936 because of the death of United Australia Party member William Foster.[1] The election was a contest between sons of politicians and both supported the UAP. The pre-selected UAP candidate was Hugh Foster, the son of the former member,[2] while Murray Robson, the son of a long serving NSW UAP politician, William Robson,[2] ran as an independent, having been an active supporter of the UAP, stating in his campaign that "I am a supporter of the UAP and of the Government".[3]
