Polling
One opinion poll was conducted and released by the in-house polling group at The Advertiser, Adelaide's main newspaper. Between one and two weeks prior to the by-election, 400 voters were polled in the seat. Voters were randomly selected at the sole pre-poll booth at Happy ValleyShopping Centre, as well as at Aberfoyle Hub. Primary votes saw 34.25 percent to Liberal, 30 percent to Woodyatt, 20.5 percent to Labor, with a collective 15 percent for the remaining five candidates. The Advertiser claimed that a Liberal primary vote below 40 percent and the high vote for Woodyatt with Labor remaining in third place, preferences could have seen Fisher retained by an independent, Woodyatt. South Australian Newspoll at the time of the by-election recorded a statewide six percent two-party swing from Liberal to Labor.
Result
Though the Liberals were favourites to win the traditionally Liberal seat, Labor's Nat Cook won the by-election by five votes with Woodyatt preferences, a 50.02 percent two-party-preferred vote from a 7.27 percent swing away from the Liberals, resulting in a change from minority to majority government. Despite this, the Jay Weatherill Labor government kept crossbench MPs Geoff Brock and Martin Hamilton-Smith in cabinet, giving the government a 26 to 21 parliamentary majority. The Liberals were successful in requesting a re-count which occurred on 15 December. Labor achieved majority government at a state level one week prior at the 2014 Victorian election. ABC psephologist Antony Green described the by-election as a "very poor result for the Liberal Party in South Australia both state and federally", and that a fourth term government gaining a seat at a by-election was unprecedented in Australian history. Much of the anti-Liberal swing was attributed to the unpopularity of then Prime MinisterTony Abbott, and additionally, the remark from then Defence Minister David Johnston several days before the by-election, where he stated he wouldn't trust South Australia's Australian Submarine Corporation to "build a canoe". Former Liberal leader Iain Evans in Davenport resigned from parliament on 30 October 2014 which triggered a 2015 Davenport by-election for 31 January. Just a couple of days before the Davenport by-election, Abbott's infamous knighting of Prince Philip occurred. Liberal Sam Duluk won the seat despite a five percent two-party swing, turning the historically safe seat of Davenport in to a two-party marginal seatfor the first time. ABC psephologist Antony Green described it as "another poor result for the South Australian Liberal Party".
