2017 New England by-election

A by-election for the Australian House of Representatives seat of New England was held on 2 December 2017.

Previous incumbent Barnaby Joyce, serving as Deputy Prime Minister and Nationals leader from February 2016 until October 2017 when his seat of New England was declared vacant, won the by-election with a large primary and two-party swing.

Background
Amid the 2017–18 Australian parliamentary eligibility crisis, the trigger for the by-election was the judgment of the High Court of Australia sitting as the Court of Disputed Returns on 27 October 2017, which found that the sitting member, Deputy Prime Minister and Nationals leader Barnaby Joyce, was ineligible under Section 44 of the Constitution to sit in the Parliament of Australia, by virtue of holding New Zealand citizenship at the time of his nomination and election. The seat was declared vacant by the High Court on the same day. Joyce had renounced his dual citizenship effective from August in order to become a sole citizen of Australia, and was thus eligible to run for the by-election.

Speaker of the House of Representatives Tony Smith issued the writ for the election on 27 October 2017, the same day as the High Court's judgment.

Candidates
Former independent member for New England Tony Windsor, who retired at the 2013 election before unsuccessfully contesting the seat at the 2016 election with a 29.2 percent primary vote, announced he would not be nominating as a candidate in the by-election. Pauline Hanson's One Nation and Shooters, Fishers and Farmers also announced that they would not run.

Results
Early in the evening, ABC election analyst Antony Green predicted an easy victory for Joyce. Claiming victory that evening, Joyce picked up a large primary and two-party swing.
