2014 Vasse state by-election

A by-election for the seat of Vasse in the Western Australian Legislative Assembly was held on 18 October 2014. The by-election was triggered by the resignation of Liberal MLA and former Liberal leader Troy Buswell on 3 September 2014, who won the seat at the 2013 election with a 57.3 percent primary and a 71.2 percent two-party vote. It was held on the same day as the 2014 Casuarina by-election in the Northern Territory.
