Body-worn camera footage of Winmar's conversation with an officer immediately after the incident was played to Bendigo Magistrates Court on Thursday.
The St Kilda star, 60, is fighting allegations he dragged a woman and smashed her head against a door at Cohuna in northern Victoria on May 14, 2025.
In the police video, Winmar could be seen telling Constable Jamie Waugh he had an argument with the woman about two hours earlier.
"We had a bit of a row, just an argument about stupid things," Winmar said.
He said he slapped the woman's arm just above the elbow but denied throwing any punches or making her tumble.
He said she was the one who punched him five or six times to the face area but he told officers he was "not going to worry about it".
Winmar told the constable he had drunk about eight beers and a couple of wines since 4pm, and the woman had also been drinking.
As he waited with Constable Waugh while First Constable Chukwuemeka Opia spoke to the woman, Winmar questioned why it was all taking so long.
"I haven't done anything wrong," he told the constable.
Constable Waugh told the court he noticed a cut to Winmar's face during their conversation and the former footballer had maintained a calm demeanour.
The woman previously told the court Winmar became unexpectedly angry before he grabbed her arm, twisted it and then dragged her by the hair.
She also accused Winmar of pushing her against a wall, spitting and yelling in her face, and then bashing her head repeatedly into a wooden door.
First Constable Opia told the court the woman appeared scared and dishevelled when he spoke to her, although he did not observe any injuries or bruising.
He also did not obtain a statement from her on the night of the incident because she was "not in the right state of mind" to provide one.
Magistrate Trieu Huynh will hand down his decision at a later date.
Winmar became the first Aboriginal footballer to play 200 games in the AFL, finishing his career with 230 games at St Kilda and 21 for the Western Bulldogs.
He fought back against racism in his career, including standing in front of an abusive Collingwood crowd in 1993, lifting his jumper and proudly pointing at his skin.
Winmar is also co-leading a landmark racism class action against the AFL in the Victorian Supreme Court.
