A by-election was held for the New South Wales Legislative Assembly electorate of Gwydir on 29 June and 20 July 1865 as a result of the Committee on Elections and Qualifications declaring that the seat of Thomas Dangar was vacant because he had an office of profit under the Crown.[1]
Dangar was elected at the 1865 election for the Gwydir in unusual circumstances. Dangar had been appointed the returning officer but was persuaded to stand for the seat, resulting in a delay of a month before the poll could be held.[2] Dangar had a contract with the Government to carry the mail on the Barwon and Namoi rivers and this was held to be an office of profit and thus disqualified him from being a member of the Legislative Assembly.
^The New South Wales Election Results database is incomplete as it is based on the report of The Maitland Mercury of 11 July 1865 which did not include returns from 5 polling places, Bingera, Gideon's Inn, Mugundie, Wellbedunga and Yetman.[8]
