Former Billabong CEO Matthew Perrin has been jailed for eight years for forging his ex-wife's signature to obtain a A$13.5 million ($14m) loan.
Perrin, 43, was last month found guilty by a jury of three counts of fraud and six of forgery after a week-long trial in Brisbane District Court.
The trial had heard that in 2008 Perrin urgently needed credit from the Commonwealth Bank to fund his failing investments.
Perrin forged his then-wife Nicole Bricknell's signature to secure a loan on their luxury Gold Coast home, which was solely in her name.
He also forged the signature of his brother Fraser Perrin as witness on the document.
