A by-election for the seat of Charlestown in the New South Wales Legislative Assembly was held on 25 October 2014.[1][2] The by-election was triggered by the resignation of Liberal-turned-independent MP Andrew Cornwell, who won the seat at the 2011 election with a 43.8 percent primary and 59.9 percent two-party vote.
The last New South Wales by-election saw a 26-point two-party swing to Labor.
