On 4 February 2002, Colbeck was appointed to the Senate by the
Governor of Tasmania under section 15 of the
Constitution, to fill the casual vacancy caused by the retirement of Senator
Jocelyn Newman. He had already been elected to the Senate at the
2001 federal election, to a term beginning on 1 July 2002. He was re-elected in 2007. Abbott nominated Colbeck for appointment to the
Abbott Ministry as the Parliamentary Secretary to the Minister for Agriculture following the
2013 federal election. Following the
2015 leadership spill that saw
Malcolm Turnbull replace Abbott as prime minister, Colbeck was appointed as the
Minister Assisting the Minister for Trade and Investment and the
Minister for Tourism and International Education in the
First Turnbull Ministry from September 2015 to July 2016. He polled an unusually high below-the-line tally, attributed to a strong "personal vote", but nonetheless lost his seat. Colbeck unexpectedly returned to the Senate in February 2018, after Senate President
Stephen Parry was caught up in the
parliamentary eligibility crisis. The
Court of Disputed Returns conducted a recount and declared Colbeck elected. Colbeck is considered to belong to the
moderate wing of the Tasmanian Liberals, and supported Malcolm Turnbull during the
2018 leadership spills; he was reportedly the only Tasmanian Liberal not to sign the petition calling for a second spill. In the new
Morrison Ministry, he was appointed
Assistant Minister for Agriculture and Water Resources. After the election, Colbeck was appointed
Minister for Aged Care and
Minister for Youth and Sport in the
Second Morrison Ministry. Between August and September 2020, Colbeck was criticised for his handling of
COVID-19 outbreaks in aged care facilities in Victoria, resulting in the deaths of 350 aged care residents as of late August 2020. There were calls by the
Labor opposition for Colbeck to be sacked as aged care minister. In September 2020, Colbeck was also censured by the
Senate by 25–21 votes for failing to take responsibility for a "crisis in the aged care sector", but he was defended by the Prime Minister who said that the majority of the sector was unaffected during the pandemic. In December 2020, his aged care portfolio was subsequently passed to health minister
Greg Hunt, with Colbeck continuing as Minister for Senior Australians and Aged Care Services and
Minister for Sport. He held these portfolios until May 2022, following the appointment of the
Albanese ministry. During Colbeck's tenure as sport minister,
Sport Integrity Australia was created in 2020 as a replacement for the
Australian Sports Anti-Doping Authority. A new
National Sports Tribunal was also created as the avenue for appeals, replacing the role of the
Administrative Appeals Tribunal. After the
2022 Russian invasion of Ukraine, Colbeck called for the
International Shooting Sport Federation to remove Russian billionaire
Vladimir Lisin as its President. ==References==
