On 28 February 2006, Sercombe announced that he was withdrawing his candidacy for re-selection, a few days before the vote of local members in which Shorten was expected to poll very strongly. As a result, Shorten was selected unopposed to contest the seat. Later in 2006, during the Beaconsfield Mine collapse, Shorten, as National Secretary of the AWU, played a role as a negotiator and commentator on developments in the immediate aftermath and the ensuing rescue operations. The mine rescue operations drew mass national media coverage, and raised Shorten's political profile ahead of the 2007 election.
