He was a Liberal Party member of the House of Representatives between November 2001 and 2022, representing the Division of Flinders in Victoria. He has previously served as a parliamentary secretary in the Howard government (2004–2007), Minister for the Environment (2013–2016), Minister for Industry, Innovation and Science (2016–2017), and Minister for Sport (2017).

From March 2020 until his retirement in May 2022, Hunt had oversight over the Australian government's response to the COVID-19 pandemic.

Gregory Andrew Hunt was born on 18 November 1965 in Frankston, Victoria. He was one of five sons born to Kathinka (née Grant, known as Tinka) and Alan Hunt. His father was a solicitor by profession who had been elected to the Victorian Legislative Council in 1962, and served as a Liberal state government minister in the 1970s and 1980s. Hunt's maternal grandmother Phyllis Forster was one of the first women to graduate from the Victorian College of Pharmacy. His mother worked as a nurse, but suffered from a form of bipolar disorder and was later institutionalised. She died of a heart attack at the age of 58, while her son was studying abroad.

Hunt grew up in Mornington, Victoria, attending Mornington Primary School and the Peninsula School. He took a gap year after leaving high school, travelling through Ireland, the Alps, Spain, and Israel. He lived on a kibbutz for several months, learning Hebrew and working in a machine shop. After returning to Australia, Hunt studied arts and law at the University of Melbourne, living at Ormond College and graduating with first-class honours. At university he developed friendships with Mary Wooldridge and John Roskam. He was head of the debating society and partnered with Rufus Black at the 1984 World Universities Debating Championship in Edinburgh, Scotland, finishing in second place. He won a prize for a final-year thesis he co-authored with Black, titled A Tax to Make the Polluter Pay.

Hunt is one of seven Liberal MPs in the 46th Parliament of Australia who have obtained degrees at an Oxbridge or Ivy League university, the others being Alan Tudge, Angus Taylor, Andrew Laming, Dave Sharma, Josh Frydenberg and Paul Fletcher.

Hunt joined law firm Mallesons Stephen Jaques after completing his undergraduate degree. In 1992 he was an associate to Michael Black, the chief justice of the Federal Court of Australia. Hunt subsequently completed a Master of Arts in International Relations at Yale University as a Fulbright Scholar. He also interned at the UN Centre for Human Rights in Geneva, "researching atrocities in the former Yugoslavia".

In 1994, Hunt began working as a senior adviser to Alexander Downer, the federal leader of opposition. He remained in Downer's office until 1998, spanning his resignation as Liberal leader and later appointment as foreign minister in the Howard government. He was the chief of the Australian Electoral Observer Mission at the 1998 Cambodian general election. Hunt subsequently worked as a senior fellow at the University of Melbourne's Centre for Comparative Constitutional Law (1998–1999), as engagement manager at management consultants McKinsey and Co. (1999–2001), and held the position of Director of Strategy at the World Economic Forum (2000–2001). He was a foundation investor in project management software company Aconex, but had to sell his shares in 2013 when he became a government minister.

Hunt was elected to the House of Representatives at the 2001 federal election, standing in the Division of Flinders. He had been asked to stand for Liberal preselection by the retiring MP Peter Reith. In 2003 he supported the invasion of Iraq by coalition forces and served as a spokesman for the Howard government's policies.
