National Australia Bank worker Brianna Younger, 25, was caught up in an operation targeting Jesse James Clarke, who is alleged to have had $500,000 in unexplained cash.

A receipt found during a search warrant of Clarke’s Baranduda home in February last year found a transaction receipt linked to Younger.

Investigations showed the bank worker had made a transaction involving $47,500 in $50 notes and $14,000 in $100 bills.

Under federal law, all Australian banks must report cash transactions of $10,000 or more.

The Wodonga Magistrates Court on Tuesday heard she made the transaction on September 15, 2016, on behalf of Clarke.

The deposit was for Clarke to help pay off a car lease for a white AMG Mercedes Benz, the court heard.

Police investigating the matter arrested Younger on March 27 and interviewed her.

She largely gave a “no comment” interview but said she had made the deposit for a friend, had been happy to do it, and knew how the banking process worked.

She then asked for the interview to be suspended so she could speak to a lawyer.

During a second interview on April 6, she said Clarke had sought her help and gave her the $62,000 in cash.

She admitted she had been stupid and should have thought about where the money came from, and that it could have been the proceeds of crime.

Lawyer Mario Vaccaro told the court his client had worked for the NAB for about three years.

“She regrets (that) she finds herself in this situation,” he said.

Mr Vaccaro asked magistrate Peter Mithen not to impose a conviction, which would mean she “doesn’t necessarily have to lose her job”.

Younger’s boss was standing behind her, Mr Vaccaro said.

Mr Mithen described the offending as “a pretty serious financial matter” and warned Younger in future to follow her obligations as a bank employee "without fail". 

He noted the consequences of people manipulating the banking system. 

The magistrate did not record a conviction and ordered Younger be of good behaviour for the next two years.
