The incident scored the footy fan a lifetime ban from all major sporting facilities in the state and criminal charges for the alleged public display of a Nazi salute, an offence punishable by up to five years in prison.
Police allege Baker-Pearce failed to learn his lesson and performed the salute a second time on the day of the semi-final, minutes after being released from the Brisbane watchhouse on the first charge.
During a brief appearance in Brisbane Magistrates Court on Monday, Baker-Pearce said he was a disability support pensioner who also volunteered at a charity organisation.
He did not enter a plea to the initial charge and was granted bail to reappear on October 17
However, detectives were waiting when he left the arrest court.
Baker-Pearce was whisked away to an interview room, arrested and marched under police escort to the watchhouse, where he was hit with the new charge over the second alleged salute.
Outside the court, he denied ever making the Nazi salute and said he was unsure why he had been charged.
"I'm innocent," Baker-Pearce said.
"I'm a loyal Australian patriot."
Baker-Pearce has twice run as an independent in state elections for Narre Warren South in Victoria in 2022 and Surfers Paradise in Queensland in 2017.
Federal Labor MP Josh Burns, who is Jewish, was publicly critical of Baker-Pearce's political tilt during the 2022 state election campaign and the Liberals' decision to put him before Labor on how-to-vote cards.
"This is a man who has stood outside Auschwitz-Birkenau taking a selfie, smiling and putting a hot emoji on it," Mr Burns told parliament.
"He has a long history of vile, anti-Semitic remarks ... but the Liberal Party decided to grant this neo-Nazi their support in the election."
