Arthur Sinodinos

Arthur Sinodinos ( ; ; born 25 February 1957) is an Australian diplomat and former Liberal Party politician, who was the Ambassador to the United States between February 2020 and March 2023. He served as Chief of Staff to Prime Minister John Howard from 1997 to 2007 and was a Senator for New South Wales from 2011 to 2019, becoming a minister in the Abbott and Turnbull governments.

Sinodinos was born in Newcastle, New South Wales, and attended the University of Newcastle. For many years, he was a public servant until becoming a political adviser. In 1997 he was appointed Chief of Staff to John Howard. After Howard's defeat at the 2007 election, Sinodinos spent time working for both Goldman Sachs and the National Australia Bank, before being appointed to fill a vacant seat in the Senate in 2011. After the Liberal victory at the 2013 election, newly-elected Prime Minister Tony Abbott appointed Sinodinos Assistant Treasurer. Sinodinos later stepped aside from his ministerial duties in 2014 during an investigation by the New South Wales Independent Commission Against Corruption (ICAC). He resigned from the Government in December 2017, due to receiving treatment for cancer. In May 2019, Prime Minister Scott Morrison announced that Sinodinos would become Ambassador to the United States.

Background and early career Sinodinos was born in Newcastle, New South Wales, to Greek immigrant parents.

Sinodinos graduated from the University of Newcastle in 1979 with a Bachelor of Commerce with Honours. He then entered the Australian Public Service as a graduate recruit, working within the Department of Finance, before working in the Department of the Treasury between 1980 and 1987 and again between 1989 and 1995. As a close confidant of the Prime Minister, he was regarded as one of the most powerful people in the country.

Corporate career Sinodinos left his position as the Prime Minister's Chief of Staff to become a director with the investment bank Goldman Sachs JBWere, and a regional general manager at the National Australia Bank; he reportedly declined an offer to become Australian Ambassador to the United States. In 2008, he was part of a panel that mediated public input into the Defence White Paper. In March 2009, he was appointed a managing director at the National Australia Bank.

Sinodinos became a director of Australian Water Holdings Pty Ltd (AWH) in 2008 and chairman in 2010. He resigned from these positions on becoming a senator.

Political career

Sinodinos was appointed to fill the vacant New South Wales Senate seat opened by the resignation of Helen Coonan on 13 October 2011. He served as honorary Finance Director (2009 to 2011) and President (2011–2012) for the NSW branch of the Liberal Party. Initially touted as a candidate for the lower house seat of Bradfield, Sinodinos was appointed to the Australian Senate representing New South Wales, replacing the resigned Liberal Senator Helen Coonan for the remainder of her term, which was due to expire on 30 June 2014. At the 2013 election he was elected to a further six-year term from 1 July 2014 to 30 June 2020. Howard was present in Parliament when Sinodinos delivered his maiden speech.

Sinodinos is a member of the board of Global Panel Foundation – Australasia, a non-governmental organisation.

During 2012 Sinodinos was a regular columnist, writing in The Australian.

On 19 March 2014, Sinodinos stood aside from his role as Assistant Treasurer prior to giving evidence as a witness before New South Wales's Independent Commission Against Corruption (ICAC). During the enquiry Sinodinos advised he was unaware of a $74,000 donation made to the Liberal Party by Australian Water Holdings, despite being Deputy chairman on a $200,000 salary. At the time of the payment Sinodinos was also Treasurer of the Liberal Party. He formally resigned on 19 December 2014 as Assistant Treasurer and was succeeded as Assistant Treasurer by Josh Frydenberg. ICAC eventually made no adverse findings against Sinodinos.

In January 2017, Sussan Ley temporarily stood aside as the Minister for Health and Aged Care and Minister for Sport and then subsequently resigned from the ministry. Sinodinos briefly acted in her portfolios until a subsequent rearrangement of the Turnbull ministry where Sinodinos was appointed as the Minister for Industry, Innovation and Science. This was later revealed to be a stage four non-Hodgkin lymphoma, for which Sinodinos required a bone marrow transplant. He was voluntarily removed from cabinet in the December 2017 rearrangement.

On 1 May 2023, The Asia Group announced that Sinodinos will chair the organization's new Australia practice.

Ambassador to the United States In May 2019, it was announced that Sinodinos would be appointed the next Australian Ambassador to the United States. He resigned as a member of the Senate on 11 November 2019. He replaced Joe Hockey as ambassador on 7 February 2020.
