Years after Rosse Eckl lost more than half a million dollars to scammers, the accountant and legal clerk agreed to help the "architects" behind a similar scheme.
The now 67-year-old laundered money by moving it - at the instructions of others - between and out of numerous bank accounts in her name or registered to her businesses, a Brisbane court has heard.
The money had been requested in fraudulent invoices sent by hackers from email addresses similar to those used by businesses.
Eckl was not accused of being a hacker or sending emails to business's clients or suppliers, but a Supreme Court jury found she facilitated the movement of significant amounts of money that she knew was the proceeds of crime.
In two "more serious" counts where victims lost money Eckl made multiple transactions involving $200,000 in one case and $1.1m in another, crown prosecutor Paul Bolster said on Thursday.
There were no financial losses in the other three counts due to some quick thinking, police action and money being frozen.
Eckl continued offending after being interviewed by police and appearing in the magistrates court on four charges.
"So there was a persistence, the Crown says, in Ms Eckl's preparedness to assist those who were the architects, the people behind the scheme that she was a part of," Mr Bolster said in his sentencing submission.
The court heard Eckl was scammed of $600,000 by people overseas after her mother died years before committing these offences.
That financial loss was difficult for Eckl to deal with but there was no evidence in the money laundering trial of her making more than a few hundred dollars used as partial payment for urgent dental treatment, defence barrister Carl Tessmann said.
Eckl had withdrawn more than $30,000 cash from her bank accounts but told police she handed that over to people she was instructed to meet around Brisbane.
"There is no allegation or proof that she knew the real source of the funds ... nor is there evidence that she knew to what use the funds would go," Mr Tessmann said.
Eckl's conduct was not sophisticated as the bank accounts were in her name or related enterprises and was unlikely to offend again.
The Malaysian-born woman moved to Australia after school to study nursing but later became an accountant.
She was employed as a legal clerk until found guilty and faces deportation if sentenced to time behind bars.
The prospect of being separated from her 80-year-old husband of more than three decades while in jail and if returned to Malaysia was distressing to Eckl, Mr Tessmann said.
Justice Paul Freeburn released Eckl on bail before sentencing on a date to be decided.
