UPDATE: The son of a Sunshine Coast woman accused of stealing $2 million from Centrelink says his mother is a good person who just made a mistake.
Judy Lorbek was arrested in Sydney, where she was holidaying with two of her three children.
Police claim the 46-year-old went on a spending spree after the $2 million was credited to her bank account, instead of a one-off $2000 payment.
Her 19-year-old son Evan has been living in the Coes Creek family home, which is undergoing renovations, while Ms Lorbek and his 14 and 15-year-old brother and sister were in Sydney.
A shaken Mr Lorbek yesterday said he did not know anything about the Centrelink mistake.
He said he thought his mum had won some money or received a payment from her ex-husband, millionaire Melbourne car dealer Srecko Lorbek.
"I knew she got a little bit of money but I wasn't sure how much because she wouldn't tell me where she got it from," he said.
"I don't even know when it happened.
"Two weeks ago things just starting happening around the house."
Police claim Ms Lorbek used some of the $2 million to pay off the mortgage and renovate her Coes Creek home, go shopping and take her children on the holiday.
It was while she was in Sydney on Saturday that Australian Federal Police arrested and charged her with dishonestly appropriating property of the Commonwealth.
Mr Lorbek said his mother had given him a small amount of money to pay for the renovations in her absence.
"She started packing up the house because she wanted to move to Sydney - that's why they were down there.
"They (the renovations) stopped a couple of days ago.
"All the tiles have been done but everything else has just stopped."
Ms Lorbek's Sydney solicitor, Bill Whitby, told a court on Saturday that the money appeared in her account because "some incompetent person in a Commonwealth agency" had made the deposit.
Mr Lorbek said if he had known about the payment mistake, he would urged his mother to give the money back.
"She should have told them that the money was in there, so I think it is wrong on that behalf," he said.
"But I also think it is wrong what Centrelink have done, the fact that they didn't get onto it straight away.
"I don't understand how you could just accidentally put $2million into a bank account."
Mr Lorbek said he and his siblings would stay with their grandparents until they found out if their home had to be sold.
"If she spent a lot of the money then they will probably take the house," he said.
"It is a bit brutal.
"She is not a bad person or anything. It is all just a mistake."
Ms Lorbek will appear in a Brisbane court tomorrow.
