The Labor MP was knocked out during a fight with two younger men while celebrating his 56th birthday at Townsville’s Mad Cow Tavern about 1am on Saturday.

Police issued the three men with public nuisance notices and banned them from the city’s Safe Night Precinct for 10 days.

The Mundingburra MP is unable to comment on the lead-up to him being knocked out and taken to hospital because he can’t remember.

“Honestly, I can’t due to the sustained head injury,” Walker told the Townsville Bulletin on Friday.

“I can’t recall what happened. The police will not let me see the video because I’ve been informed by the police and my legal people it will taint me giving evidence in the statement.”

Walker serves as a Temporary Speaker of Parliament and on the Transport and Resources Committee.

Premier Annastacia Palaszczuk issued a brief statement on Thursday saying she had accepted Walker’s apology for the incident, indicating that he will not face any disciplinary action.

“She made it very clear what her standards are about what she expects from her colleagues and her team,” he said.

“I understand that clearly.”

Despite not being able to remember what happened, the MP said he was still trying to play the scene over in his head.

He is contrite and has promised not to get himself in that position again.

“I wish to apologise to the people of the seat of Mundingburra. I will work even harder to regain that trust,” he said.

“It’s disappointing, I don’t want to go through it again.”

Walker, a former corrections officer, was elected to replace retiring Disability Services Minister Coralee O’Rourke at the November election.
