Husar worked in the retail and service sectors. She joined the Labor Party in 2013 and became president of the Penrith Branch in 2015. Husar was unsuccessful as the ALP candidate for the seat of Penrith in the 2015 New South Wales state election, but won the seat of Lindsay by defeating the sitting Liberal MP Fiona Scott in the 2016 federal election by a swing of 4.1 percent. Lindsay was regarded as a key marginal seat. During her term in office, Husar sat on parliamentary committees for the National Disability Insurance Scheme; Employment, Education and Training; and Social Policy and Legal Affairs.
Internal Assessment
In July 2018, it was reported that Husar had been the subject of an internal assessment commissioned by the NSW Labor Party since March regarding staff complaints of workplace bullying and misconduct. Husar denied the allegations and took personal leave shortly afterwards, citing threats of violence directed towards her. The investigation conducted by barrister John Whelan upheld complaints that Husar had behaved offensively and unreasonably towards her staff. Separately, claims of lewd conduct and misleading the parliament were rejected. Legal advice based on this assessment prompted the NSW Labor Party to report that there was no basis for Husar to resign from parliament.
Endorsement
Husar had already been re-endorsed as the party's candidate at the 2019 election, but announced on 8 August 2018 she would not recontest her marginal seat. Labor accepted her decision. In an interview on the ABC's7.30, Husar said "slut shaming" led to her decision to resign. In November 2018, Husar said she had changed her mind and disputed that she had ever ceased to be endorsed as the Labor candidate. Husar sought intervention by Labor leaderBill Shorten, who stated that it was not in the best interests of the ALP or Husar for her to recontest the seat. On 7 December 2018, NSW Labor formally disendorsed Husar from recontesting the seat of Lindsay. She subsequently stated that she would challenge the disendorsement. On 11 December, Labor officially selected Diane Beamer. Apparently, Husar did not nominate for the ALP preselection ballot. On 11 April, she confirmed that she would not contest the seat as an independent at the 2019 federal election.
Defamation proceedings
In early December 2018, Husar announced that she had launched defamation proceedings in the Federal Court of Australia against BuzzFeed, the originator of the investigation-story, and a reporter. Husar claimed the publication of unsubstantiated allegations without the right of reply lead to a media storm which ruined her career, thus causing economic loss. In July 2019, Husar and Buzzfeed reached an out-of-court settlement. Buzzfeed subsequently published an apology but avoided admitting liability over the article, instead they did agree to taking it offline.
Expenses breaches
In March 2019, The Sydney Morning Herald reported that Husar had repaid $2300 to the Independent Parliamentary Expenses Authority after an audit found that there had been twenty-one individual breaches of travel expenses in an eighteen-month period. Husar explained that approximately ten per cent of the total was related to knee surgery and pneumonia in August 2016.
Personal
Husar is of Polish descent. She has three children and is single. In a November 2016 parliamentary speech, Husar revealed that she grew up in a family with a history of domestic violence perpetrated by her father.
