Roxy Jacenko's husband Oliver Curtis to spend Christmas behind bars after appeal is dismissed.

Sydney banker Oliver Curtis will spend Christmas behind bars, after an appeal over his conviction for insider trading was dismissed this morning.

The 31-year-old father of two was sentenced to two years jail on 24 June, after a Sydney court found him to have illegally profited $1.433 million from confidential trading information provided to him by his best friend.

Curtis’ legal team lodged an appeal in July, shortly after his wife, PR mogul Roxy Jacenko, was diagnosed with breast cancer.

During the high-profile case, the court heard Curtis had made 45 trades based on price-sensitive information supplied by former Orion Asset Management employee John Hartman between May 2007 and June 2008.

Hartman agreed to help ASIC in their prosecution of Curtis as part of a bid for his reduced three-year sentence, leading to charges being laid against him in January 2013.

Today’s ruling comes just a day after Jacenko spoke to Who about cancelling Christmas plans due to her husband’s imprisonment.

“My mum said to me the other day, ‘I think I’m going to go and get a Christmas tree.’ And I said, ‘You can’t, because I told Pixie and Hunter their father would be home for Christmas’,” the 36-year-old said.

“It was so far away then… Now, here we are.”
