A by-election in the seat of Johnston in the Northern Territory was held on 29 February 2020,[1] following the resignation of Ken Vowles, the MLA for Johnston, on 31 January 2020.[2] Vowles was first elected in the 2012 Northern Territory general election, winning 45% of first preference votes and 55.7% of the two-party-preferred vote.[3] At the 2016 Northern Territory general election, Vowles was re-elected with 51% of first preference votes and 64.7% of the two-party-preferred vote.[4]
Former AFL footballer Joel Bowden won the by-election, representing the Labor Party.[5] In a highly unusual move, the Greens preferenced Labor last on their how-to-vote cards (HTVs), even behind the Country Liberal Party (CLP), due to Labor's support for fracking.[6]
A total of 7 candidates were declared nominated by the NTEC.[7]
