The 2011 redistribution, which took effect at the 2013 election, saw Pilbara gain the Shire of Roebourne from the renamed North West Central electorate, in exchange for the remnants of the Shire of Ashburton, and the Shire of Ngaanyatjarraku was ceded to the Kalgoorlie electorate. That theoretically increased Labor's hold on the seat, but the popularity of the WA Nationals' Royalties for Regions policy made it marginal, so much so that, at the election, it was comfortably won by the then Nationals' leader, Brendon Grylls.
