However, there is no evidence to suggest Mr Minns had any knowledge of the alleged scheme.

The claims were made by Jonathan Yee, an aspiring Labor candidate and restaurant manager, who said he arranged for fake donors to sign $900 cheques which were made out to Mr Minns' 2015 campaign account, in exchange for cash.

Mr Yee said the alleged scheme was designed to evade electoral laws by hiding the identities of the true donor or donors.

Mr Yee told the ICAC hearing the scheme was proposed by then-Labor MP Ernest Wong who was known to be a prolific fundraiser.

"Ernest would ask me … do you have people who could write a few cheques out to the ALP Chris Minns account?" Mr Yee said.

"Once those cheques were received I would have handed them to Ernest and [he] would hand me the cash as required."

Mr Yee said he asked for the "fake" donors, including restaurant workers, to leave the recipient line blank.

Counsel Assisting, Scott Robertson, demanded to know where the money was coming from.

"Who was the true source of the Minns donation?"

"I never asked," Mr Yee replied.

"My job what was to do what was asked of me and I never asked more."

A spokesman for Mr Minns told the ABC the money had been accepted in "good faith."

"Mr Minns will forfeit funds associated with Mr Wong and Mr Yee," the spokesman said.

Mr Yee also admitted being the "mastermind" of another scheme, which enlisted "foot soldiers" to act as fake donors in order to disguise a $100,000 payment to the Labor Party in 2015.

The commission has heard Chinese billionaire and banned donor Huang Xiangmo personally brought the cash into ALP headquarters.

Mr Huang denies wrongdoing.

Mr Yee said Mr Wong asked him to organise fake donation forms, but didn't reveal the true source of the money.

"You knew who the donor was, didn't you?" asked Chief Commissioner Peter Hall QC.

"I did not know," he replied

"You're joking aren't you?"

Mr Yee said Mr Wong had "probably" mentioned the billionaire's name in connection with the donation.

The hearing continues.
