On 12 June 2012, Christian Porter, the treasurer of Western Australia since 2010 and Attorney-General of Western Australia since 2008, announced his resignation from those roles in order to seek preselection for the Division of Pearce. Porter retained the seat for the Liberal Party. In his bid for re-election in 2016, however, Porter suffered a five-point swing to reduce his margin to seven percent, just barely within the range of being fairly safe.
