Sir Guy Green is the current Governor of Tasmania. In 2003, following the controversy of Peter Hollingworth's past handling of child abuse allegations, Green became the acting Governor General of Australia because by then he was the seniormost state governor. When Hollingworth officially resigned in May 2003, Green became the Administrator of the Government, or in effect acting Governor-General, of Australia, serving until Michael Jeffery took office in August 2003.

Sir Guy was born in Launceston, and was Tasmania's first Tasmanian-born governor. He was knighted in 1982 and became Governor of Tasmania in 1995.
