Bennelong by-election, 2017

A by-election for the Australian House of Representatives seat of Bennelong will be held on 16 December 2017.

The trigger for the by-election was the resignation of the sitting member, John Alexander of the Liberal Party, on 13 November 2017. Alexander resigned due to having held British citizenship, meaning he was ineligible under Section 44 of the Constitution to sit in the Parliament of Australia. This resignation was part of the 2017 Australian parliamentary eligibility crisis. Alexander renounced his British citizenship in order to nominate for election again.

Bennelong was one of the electoral divisions to record a No vote in the 2017 Australian Marriage Law Postal Survey, with 49.8% Yes votes and 50.2% No. It was among 17 to record a No vote out of 150 nationally, although one of 12 in NSW.
