County Court judge Claire Quin said Chun Wa Wong and a co-accused had flown from Melbourne to Sydney on February 25 this year before catching a taxi to North Sydney for the money exchange.

The pair met an unknown third person outside the railway station who handed over the money after Wong’s co-accused had provided a password.

Wong and the co-accused flew back to Melbourne later that day.

Judge Quin said the pair had the two bags containing $800,080 in cash in their car and were driving from the airport to Box Hill before police intercepted them on Elgar Road.

Wong, 29, pleaded guilty on Tuesday to one count of money laundering.

Judge Quin said Wong had been working for the Bank of China in Hong Kong before becoming involved with the money-laundering syndicate.

She was working for a bakery in Melbourne on a temporary working visa when she agreed to travel with her co-accused to Sydney to pick up the money.

‘‘It was conceded by the prosecution that you were a lesser player in this offence than your co-accused ... and other unidentified third parties involved in the scheme,’’ the judge told Wong.

‘‘I was referred to portions of the depositions where it was clear that you reported to others above you in the hierarchy and followed their directions.

‘‘You did not receive or anticipate receiving any financial reward for your involvement.’’

Wong expected to be deported once she had served her jail sentence.

The judge said Wong had spent her early childhood with her parents in Hong Kong before being sent to live with her grandparents in Guangzhou, China. She then moved back to Hong Kong to complete her secondary education.

‘‘Your father passed away in 2007 and you have since been working to support your mother and extended family,’’ the judge said.
