Sydney executive found guilty over NAB fraud

An event management company executive has been found guilty on dozens of fraud and bribery charges after splashing millions of dollars in kickbacks to bribe a former senior National Australia Bank staffer.

Helen Mary Rosamond, 47, was accused of defrauding NAB by sending falsified and inflated invoices from Human Group to the bank and paid millions of dollars in gifts to Rosemary Rogers to ensure they were paid.

A NSW District Court jury today found Rosamond guilty on 69 counts of 92 including corruptly giving Rogers hundreds of thousands of dollars worth of benefits between 2013 and 2017.

Rogers, the now-convicted former chief of staff to the National Bank of Australia's chief executive, told the trial she received a house, a BMW car, a boat, holidays and other benefits after approving false bank invoices for Rosamond.

The costs are believed to have totalled more than $26 million.

Rosamond was acquitted of one charge.

Justice Robert Sutherland has asked the jury to continue deliberating on the remaining 22 counts.
