The poster on the corner of Waverley and Stephensons roads in Mount Waverley – which has since been replaced – was vandalized with a blue marker on the face of the Chinese-Australian candidate.
The text seems to accuse the incumbent MP of being affiliated with the Chinese Communist Party (CCP), an assertion raised since her election in 2019, and which she has repeatedly denied.
In a text response to SBS Chinese about the incident, Ms Liu said, “I will not comment on my opponents and their dirty campaigns.”
Victoria Police confirmed they had not received any reports of vandalism.
Local resident Stephanie Lam said Ms Liu’s posters had been targeted several times, including one instance where the politician’s eyes and mouth were covered in white duct tape.
Ms Liu was elected to parliament in the 2019 elections but has been at the center of accusations over her links to China.
During the last election, the Labor Party raised questions about the Hong Kong-born politician’s membership in Chinese organizations linked to the CCP.
At the time, Prime Minister Scott Morrison called the opposition’s campaign tactics “libel”.
In an interview with SBS Chinese last month, the Mandarin- and Cantonese-speaking MP said she was of Chinese descent but was acting in Australia’s best interests.
In this interview, she encouraged listeners to look at her record for the past three years if they still had any doubts about her loyalty to Australia.
Ms. Liu also noted that those who accused her of being “pro-China” were unable to provide evidence.
She holds the seat by a very slim margin of 0.57% or just over 500 votes after beating Labor’s Jennifer Yang in 2019.
Labor sees Chisholm as a “must-win” to form a government and are counting on Victorian Trades Hall Council deputy secretary Carina Garland to claim the seat.
The incident comes amid controversy over an advertising campaign by Advance Australia, a conservative lobby group that accuses Labor of being “weak” on China.
A Labor Party election campaign spokesman told SBS Chinese they would not comment on the incident.
