Deputy Premier Jackie Trad has labelled racists as "cowards" after a Nazi symbol was left on her south Brisbane office window.
On Thursday night Ms Trad tweeted a photo of a swastika sticker, plastered over her face on the office window, and said it was a scare tactic that would not work.
"It’s not a coincidence that this happened after I spoke out against [Senator Fraser] Anning’s and the [Katter's Australian Party]’s appalling racist views on immigration," she wrote.
"But the standard you walk past is the standard you accept - and these scare tactics won’t stop me from calling out racism."
A statement from Katter's Australian party said "obviously any use of Nazi imagery is wrong".
Senator Anning's maiden parliamentary speech, in which he used the term Nazi-era "final solution" in relation to immigration, was denounced by Ms Trad and the Premier Anastasia Palaszczuk as unacceptable.
The Premier stripped the Katter's Australian Party of five parliamentary staff after the party refused to disavow Senator Anning's speech, causing an ongoing war of words.
“I know first-hand how damaging this kind of rhetoric is," Ms Trad said in August of Senator Anning's speech.
"But it doesn’t come from nowhere.
“People like Senator Anning and his former colleagues in One Nation are encouraged by the deafening silence from the LNP, failing to call out their electoral preference partners on hateful, racist remarks.
“It’s not good enough. This isn’t the future I want for our state and I will call it out every single time.”
A spokesman for the KAP said any claim that Senator Anning was anti-Semitic or racist was "moronic" and Ms Trad had ignored the support the party had from the Jewish community.
The swastika sticker left at Ms Trad's office was labelled the Antipodean Resistance, a neo-Nazi organisation.
