Far-right activist Neil Erikson has defied a court order requiring him to return his uniforms to his former employer, freight company Toll, sparking a call for him to be charged with contempt of court.

Mr Erikson has been wearing the uniform in videos containing controversial rants posted to social media and during well-publicised incidents, including when he ambushed former senator Sam Dastyari in a Melbourne pub, despite being sacked by the company last May.

Toll alleged he has been lending the uniform to a friend and fellow far-right activist, Ricky Turner, who was pictured wearing it on the front page of a major daily newspaper engaged in a scuffle outside the venue where controversial British commentator Milo Yiannopoulos was speaking.

The company launched legal action in the Federal Circuit Court almost a fortnight ago and obtained court orders requiring Mr Erikson to return the uniforms by last Thursday and stop damaging the company's reputation.

Toll received more than 500 complaints from customers following the publication of the video of Mr Erikson wearing the company's uniform and confronting Mr Dastyari, according to court documents.

The company alleged many customers threatened to never do business with Toll again.

Barrister Martin Garrett told a hearing on Tuesday Mr Erikson had since breached a number of the court's orders including failing to return the uniforms.

He said Mr Erikson had told the company "most of the uniform was damaged and thrown out during the years … what was left was discarded a while ago and is no longer in my possession".

But Mr Garrett told the hearing that just a month earlier, Mr Erikson had pledged to return it, and hadn't offered an explanation for contradicting himself in his latest correspondence.

Judge Suzanne Jones asked Mr Erikson, who took part in the hearing over the phone, if he was "seriously saying" he didn't have the uniforms anymore.

"It's pretty obvious to me that you [and Ricky Turner] are pretty close and … I have an exhibit where a person who looks awfully like him … you know the Herald Sun front page … Mr Turner hoeing into someone … in a Toll uniform," she said.

But Mr Erikson told the hearing Mr Turner had been given a brand new Toll shirt from another friend.

"I have none of the uniforms, I discarded them after the Dastyari incident," he said.

Lawyers acting for Toll made an application for Mr Erikson to be charged with contempt of court for breaching the court's orders.

But Judge Jones adjourned the application until mid-January to give Mr Erikson more time to engage a lawyer and file affidavits to support his submissions.

She warned him that he would be arrested and brought to court if he failed to attend the hearing in person.

Mr Erikson responded that he would be at the hearing but was unemployed and couldn't afford to pay a lawyer.

The court heard he will need to supply evidence about what happened to the uniforms as well as an affidavit from Mr Turner swearing that he received the Toll shirt from someone else.

Mr Erikson told the court he would immediately rectify other alleged breaches of the court's orders, including by deleting a video he'd published to YouTube of the incident involving Mr Dastyari.
