Teena McQueen, a former vice-president of the Liberal Party, has died after a severe illness just weeks after defecting to Pauline Hanson's One Nation, her family and party officials confirmed.
Sudden death after political switch
McQueen, 58, died on Wednesday in a Brisbane hospital. She had been diagnosed with a rare autoimmune condition that rapidly deteriorated, according to a statement from her family. She defected to One Nation in early June, citing dissatisfaction with the Liberal Party's direction under Peter Dutton.
“Teena passed away peacefully surrounded by family after a brave fight,” the statement said. “Her commitment to public service and her recent move to One Nation reflected her deep desire to represent everyday Australians.”
Political career and defection
McQueen served as Liberal vice-president from 2018 to 2022 and was a prominent figure in Queensland politics. Her defection to One Nation was seen as a blow to the Liberal Party ahead of the next federal election. In a statement at the time, she said the Liberal Party had “lost its way” and that One Nation “better represents the values of hardworking Australians.”
One Nation leader Pauline Hanson expressed shock at McQueen's death. “Teena was a passionate advocate for her beliefs and had so much more to give,” Hanson said. “Our thoughts are with her family.”
Reactions and tributes
Liberal Party officials also paid tribute. A spokesperson said: “Teena McQueen served her party and country with dedication. We are saddened by her passing.”
McQueen's death raises questions about the future of her defection and its impact on One Nation's campaign. She was expected to run as a candidate in the next Queensland state election.
