A by-election was held for the New South Wales Legislative Assembly electorate of Bingara on 14 September 1904 because Samuel Moore had been appointed Secretary for Mines in the Carruthers ministry.
[1] Until 1904, members appointed to a ministerial position were required to face a by-election.
These were generally uncontested.
On this occasion a poll was required in Bingara, Glebe (James Hogue) and Tenterfield (Charles Lee) and all were comfortably re-elected.
The four other ministers, Joseph Carruthers (St George), James Ashton (Goulburn), Broughton O'Conor (Sherbrooke) and Charles Wade (Gordon), were re-elected unopposed.
