Martin Hamilton-Smith

During his time in parliament, Hamilton-Smith has served in a range of ministerial portfolios in the Cabinet of South Australia, including those with a responsibility for investment and trade, small business, defence and space industries, health industries, veterans’ affairs.

Hamilton-Smith announced on 6 January 2018 that he would not seek re-election in the 2018 election.

On 6 January 2018 Hamilton-Smith announced that he would retire at the 2018 state election and resigned from the Weatherill Ministry with immediate effect.

Hamilton-Smith was appointed to the ministerial portfolio of small business in 2016. In September 2017 he was appointed as a minister with responsibilities for space industries and health industries. Major achievements over four years as a minister included helping to retain $90 billion worth of submarine and shipbuilding work in SA, establishing Investment Attraction South Australia, construction of the Centenary of ANZAC Memorial Walk along Kintor Avenue, hosting the International Space and Astronautical Congress in Adelaide as Australia's first space industries minister, and improving communication of small business through the establishment of a small business roundtable.

He became an independent two months after the 2014 election. He served as the Minister for Investment and Trade, Minister for Defence Industries and Minister for Veterans’ Affairs in the Weatherill Labor cabinet from May 2014 until January 2018 and Minister for Space Industries and Minister for Health Industries from September 2017 until January 2018.

The 2014 election resulted in a hung parliament with 23 Labor seats, 22 Liberal seats, and two independents. The balance of power was held by crossbench independents Geoff Brock and Bob Such. Such did not indicate who he would support in a minority government before he was diagnosed and hospitalised with a brain tumour and took medical leave. With 24 seats required to govern, Brock backed Labor. He accepted the cabinet positions of Minister for Regional Development and Minister for State and Government Local Relations. Brock agreed to support the Labor government on confidence and supply while retaining the right to otherwise vote on conscience.

On 27 May 2014, more than two months after the election, Hamilton-Smith in a media conference with South Australian Labor Premier Jay Weatherill announced his decision to resign from the South Australian Liberal Party to become an "Independent Liberal" MP, and to join the Labor cabinet as the Minister for Trade, Defence Industries and Veterans' Affairs. Though his vote was not crucial to the government, he agreed to support the Labor minority government on confidence and supply while retaining the right to otherwise vote on conscience, stating that South Australian business needed a stable parliament.

Labor unexpectedly won the 2014 Fisher by-election by five votes from a 7.3 percent swing, giving them majority government. Despite this, the Jay Weatherill Labor government kept Brock and Hamilton-Smith in cabinet, giving the government a 26 to 21 parliamentary majority.

Redmond resigned on 31 January 2013. Hamilton-Smith chose to support Steven Marshall who was elected leader unopposed. Hamilton-Smith was appointed Shadow Minister for Economic and Regional Development, Mineral Resources and Energy, Manufacturing, Industry and Trade, and Defence Industries in the subsequent reshuffle.

Hamilton-Smith nominated for the position of South Australian Liberal parliamentary leader, with Steven Marshall as deputy leader after Hamilton-Smith declared a leadership spill against Isobel Redmond and Mitch Williams. A partyroom ballot occurred on 23 October 2012, Redmond retained the leadership by one vote, however Marshall was elected to the deputy leadership.

On 30 March 2010, Hamilton-Smith was elected deputy leader of SA Liberals to replace Steven Griffiths in a party-room vote, defeating Iain Evans 10 votes to 8. He once again defeated Evans in a leadership position in a rematch between the two former leaders.

Hamilton-Smith accused Labor of accepting split donations from the Church of Scientology based on information sent to the Liberal Opposition that was subsequently found to have been forged. This controversy coupled with the Frome by-election and continued poor polling, saw Liberal MPs openly talk of a leadership change, with a high chance of a leadership spill likely, prior to the 2010 state election. Two days later, Hamilton-Smith announced a spill of the leadership and deputy leadership, with a ballot taking place on Saturday 4 July 2009. Williams, Isobel Redmond, and Iain Evans ruled out contesting the ballot, with Hamilton-Smith and his moderate deputy Vickie Chapman the only contenders. Hamilton-Smith defeated Chapman in the leadership spill, 11 votes to 10, with one MP abstaining. At first, Hamilton-Smith immediately announced he would stand down, which would have delivered the leadership to Chapman. Hamilton-Smith announced a second leadership ballot to be held on Wednesday 8 July. On Monday 6 July, Hamilton-Smith confirmed he would not be running for the leadership. Contenders for the leadership were Chapman, Redmond, and Williams. Hamilton-Smith and his supporters backed Redmond. Redmond won the leadership spill on 8 July 2009, 13 votes to 9 against Chapman.

Under his leadership, polling by Newspoll saw the Liberals go from 29 to 40 per cent on the primary vote, and from 39 to 50 per cent on the two party preferred vote. The Preferred Premier rating saw Hamilton-Smith start on 21 per cent, seven points higher than his predecessor, to a high of 30 per cent, with Rann falling from a high of 64, to 48 per cent. However, Newspoll saw Labor back in a winning position on 54 to 46 in late 2008, and then 56 to 44 in early 2009 along with a widening gap in the Preferred Premier rating. During the 50-50 polling, The Sunday Mail polling suggested that whilst there had been large swings away from the government in country areas, support was holding relatively firm at 2006 election levels in the metropolitan areas. However, this did not play out at the 2009 Frome state by-election sparked by the parliamentary resignation of former Premier Rob Kerin, which saw a rare two-party swing from the opposition to the government, and resulted in independent Geoff Brock taking the seat from the Liberals on preferences.

In October 2005, he moved to challenge then Liberal leader Rob Kerin, but later withdrew his challenge. On 11 April 2007, Hamilton-Smith formally challenged then Liberal leader Iain Evans, and was successful with 13 votes to 10 for the Liberal leadership. On 19 April 2007, he announced a re-shuffle of the opposition front bench.

At the 2002 election when Rann Labor came to power, Hamilton-Smith retained his seat by twelve percent against Labor on 2PP, and by four percent at the 2006 election. Hamilton-Smith was promoted by Premier John Olsen into the position of Cabinet Secretary on 5 October 2001 and was later elevated into Cabinet as the Innovation and Tourism minister in the Kerin Liberal government from December 2001 to March 2002.

Hamilton-Smith first won Waite in the 1997 election by six percent against the Democrats on a two-candidate basis. Ahead of the election, he ran for Liberal preselection in Waite as a non-factionally-aligned conservative, defeating both Robert Lawson from the moderate faction and Hugh Martin from the conservative faction. Previous Waite MP Stephen Baker, from the moderate faction, resigned two months prior to the election which was seen as a result of losing the deputy leadership after the coup of leader Dean Brown from the moderate faction, by John Olsen from the conservative faction. The preselection victory of Hamilton-Smith prompted Brown to complain of interference by federal conservative faction MPs Nick Minchin, Grant Chapman, and Andrew Southcott.

Hamilton-Smith left the Army in 1995 to build a property development, investment and private child care centre business which had been first established in 1989. The family business employed around 125 staff at six business sites in two states, South Australia and New South Wales, and involved the construction of new facilities and the trading operation of the enterprises. Hamilton-Smith became President of a South Australian-based childcare association and National Secretary of the Australian Confederation of Childcare and editor of the ACCC national magazine from 1995 to 1997. These bodies represented the small business sector of childcare before federal and state parliaments.

He commanded Australia's first counter-terrorist assault force in the SAS in 1980. He saw service in Malaysia and as commanding officer of the 1st Commando Regiment based in Sydney.
