Finocchiaro was born in the Northern Territory and grew up in Palmerston. She attended local primary schools before completing her secondary education at Kormilda College. While in high school, she became "the highest-ranking army cadet in the Northern Territory". She studied the International Baccalaureate diploma, then graduated with a double degreein law and international studies from the University of Adelaide. She returned to Darwin in 2008, and was admitted as a legal practitioner in the Northern Territory, commencing work as a graduate clerk at the Clayton Utzlaw firm. She also received a Graduate Diploma of Legal Practice from Charles Darwin University.
Parliament
In 2012, the Country Liberal Party preselected Finocchiaro for the central Palmerston seat of Drysdale in that year's election, instead of sitting CLP member Ross Bohlin, who unsuccessfully ran against her as a conservative independent. She was the youngest MLA in the history of the Legislative Assembly. On 7 March 2013, Finocchiaro was elevated to the Second Mills Ministry, becoming Minister for Sport and Recreation, Racing, Statehood, Young Territorians and Senior Territorians. Aged 28, she was the youngest minister in Territory history. However, she was dropped from the ministry on 14 March after Adam Giles successfully challenged then-Chief Minister Terry Mills only a week later. Following a redistribution of electoral boundaries, Finocchiaro sought CLP preselection for the new seat of Spillett, taking in strong conservative suburbs between Darwin and Palmerston—including her base in Durack. She defeated Treasurer Dave Tollner for CLP preselection. Finocchiaro went into the 2016 election with a notional majority of 17.9%, making Spillett the CLP's safest seat in Darwin/Palmerston at the time.
CLP deputy leadership
On election night, the Territory swung heavily to Labor, which won a landslide majority government. However, Finocchiaro weathered this massive Labor wave with only a small swing against her in Spillett, proving to be in the least danger of the CLP's elected members. She was the only CLP member whose reelection was assured on election night, and for a few days it was possible that she would be the only CLP member left in the legislature. Ultimately, Finocchiaro was joined by fellow second-term member Gary Higgins. Meanwhile, her previous seat of Drysdale was lost to Labor candidate Eva Lawler. On 2 September, Higgins, the sole survivor of the Giles cabinet, became CLP leader and opposition leader, with Finocchiaro as his deputy. Finnochiaro faced the task of helping the CLP recover from one of the worst defeats of a sitting government at the state or territory level in Australia. The CLP was recognised as the Official Opposition after the Solicitor-General advised that the five independents could not realistically form an alternative government. Although the CLP was well short of the numbers for official status in the chamber, the new Labor government of Michael Gunner promised that the CLP would be properly resourced as an opposition. As the sole opposition MPs in the Assembly, Higgins and Finocchiaro divided all opposition portfolios between them. Finocchiaro served as Shadow Minister for Justice and Attorney-General, as well as Shadow Minister for Police, Fire and Emergency Services, Health, Children, Territory Families, Education, Trade, and Essential Services. She also serves as Opposition Whip. Under these circumstances it was unusual that Finocchiaro is given this position, since the Opposition Whip is responsible for ensuring party MPs toe the official party line. However, Finocchiaro did not have any responsibility to keep anyone in line since there were only two members in the CLP party room, herself and Higgins.
Leader of the Opposition
On 1 February 2020, Higgins resigned as CLP leader and opposition leader, with Finocchiaro replacing him. Former Chief Minister and Territory Alliance Leader Terry Mills claimed to have replaced her as Opposition Leader on 18 March 2020, however this claim was not formalised by the Legislative Assembly. On 24 March, Finocchiaro raised a motion under standing orders which allowed the assembly to decide on the opposition party, with the CLP winning opposition status by 5 votes to 3.
Personal life
Finocchiaro is married to Sam Burke, the son of former NT chief ministerDenis Burke. She is of Italian descent and has been "heavily involved in the NT's Italian community", including as CEO of the Italian Festival Association of the Northern Territory.
