Barnaby Thomas Gerard Joyce (born 17 April 1967) is an Australian politician who served as the 17th deputy prime minister of Australia under Malcolm Turnbull from 2016 to 2018 and under Scott Morrison from 2021 to 2022. He was the leader of the National Party of Australia. Joyce was born in Tamworth, New South Wales, and is a graduate of the University of New England. In 1999, he set up an accountancy practice in St George, Queensland. Joyce was elected to the Australian Senate at the 2004 federal election, taking office in 2005. He became the National Party's Senate leader in 2008. At the 2013 election, he transferred to the House of Representatives, winning the rural seat of New England in New South Wales. During 2013, Joyce replaced Nigel Scullion as deputy leader of the National Party. He succeeded Warren Truss as party leader and deputy prime minister in 2016. In the Abbott and Turnbull governments, Joyce served as Minister for Agriculture (2013–2015), Minister for Agriculture and Water Resources (2015–2017), Minister for Resources and Northern Australia (2017) and Minister for Infrastructure and Transport (2017–2018). During the 2017–18 Australian parliamentary eligibility crisis, Joyce was confirmed to be a dual citizen of New Zealand, which is forbidden under Section 44 of the Constitution of Australia. On 27 October 2017, the High Court of Australia ruled that he had been ineligible to be a candidate for the House of Representatives at the time of the 2016 election. Joyce re-entered parliament in December 2017 after winning the New England by-election with a large swing against low-profile opposition. In February 2018, he resigned his ministerial and leadership roles after acknowledging that he was in a relationship and expecting a child with a former staffer. He was succeeded by Michael McCormack, but remained in the party as a backbencher. In June 2021, Joyce defeated McCormack in a leadership spill to return as deputy prime minister. Following the Liberal-National coalition's loss at the 2022 federal election, Joyce was replaced by David Littleproud as leader of the National Party, after a leadership challenge and is now the Shadow Minister for Veterans' Affairs.
