With an eight-year term, Dessau is the longest-serving governor of Victoria since 1974, when
Major General Sir Rohan Delacombe, KCMG KCVO KBE CB DSO concluded an eleven-year term. Announcing a three-year extension to her five-year term in 2019, the
premier of Victoria,
Daniel Andrews, said of Dessau and her husband,
“Through their tireless work they have wonderfully represented and celebrated our diverse community and its achievements at home and internationally, while making Government House a more open, accessible and inclusive place.” On 1 November 2021, Dessau succeeded Queensland governor
Paul de Jersey as the longest-serving incumbent state governor. Although she had received a commission to act as
Administrator of the Commonwealth in the absence of the
governor-general of Australia following her appointment in 2016, it was only after becoming the longest-serving state governor in 2021 that she was routinely called on to fulfill that role.
La Trobe University's 2022 honorary doctorate citation said, "As Governor, she has carried out her constitutional responsibilities and ceremonial duties with distinction and worked tirelessly in the community and international engagement activities." Dessau is one of five Jews to have served in a viceregal capacity in Australia, after governors-general
Sir Isaac Isaacs and
Sir Zelman Cowen, and governors
Sir Matthew Nathan (Queensland) and
Gordon Samuels (New South Wales). In August 2016, Dessau was embroiled in an expenses scandal, which saw her personally repay the expenses of lunches at a
Gordon Ramsay restaurant (
Pétrus) and
Harrods, which had originally been paid by the Victorian taxpayer. In 2016, the level of expenses for capital works and ongoing maintenance requested by Dessau were alleged to be excessive, and a former
Government House employee told the
Herald Sun that the working environment there was "toxic". On the expiration of her term on 30 June 2023, she was succeeded by
Margaret Gardner, the then-vice chancellor of Monash University. At the same time as announcing Professor Gardner as the 30th governor of Victoria, the premier thanked Dessau "
for her outstanding leadership and compassion during some of our state’s most challenging times. The Governor and her husband Anthony Howard AM KC have supported, represented and championed our diverse community with grace and dedication.” Dessau was appointed a Commander of the
Royal Victorian Order (named for
Queen Victoria, not the state) by
Charles III in the
2023 New Year Honours. The order is within the personal gift of the sovereign, and recognises distinguished personal service to the monarch. ==Personal life==
