Luke Brett Moore, 27, opened an account called 'Complete Freedom' with St George Bank in 2010 - and it gave him just that.Due to a technical glitch, the bank placed no limit on the amount he could be overdrawn.
Luke decided not to tell the bank and made 50 transactions over the next years to a total of almost $2million .Initially, he used it to pay his mortgage and general bills.
But then Luke realised he was able to make transfers of as much as $50,000 at a time.He bought a Hyundai Veloster and then drove from his home in Goulburn, New South Wales, to Sydney to pick up a $36,000 Maserati.
He then moved out to the Gold Coast, attempted to set up a business but spent much of his time partying.
Luke told the BBC:
"It was a crazy time for me.""I was a young and foolish 22-year-old and I wasn't thinking particularly clearly.
"I was just doing what most young guys do when they're that age and they've got a bucket load of cash - just having fun and partying.
"I went to strip clubs and spent hundreds of thousands of dollars on girls, alcohol, cocaine and whatever else."
He was sentenced to four-and-a-half years in jail.Luke spent six months behind bars but has now successfully had his conviction overturned.
A Court of Appeal agreed that he had no legal obligation to inform St George Bank of what was happening.
