In the wake of his corporate theft, he went on to have a whirlwind romance with Bachelor star Tahnee Leeson, but the pair split on the ‘evening of Mother’s Day’ in 2025, just weeks after they welcomed their son Arlo.Now, rumours are swirling that McKeone has pursued a romance with Sarah Hughes (née Borthwick), a mother of three from Perth.

Before his legal troubles, McKeone was best known for his brief marriage to former Miss Universe Australia Olivia Molly Rogers A civil court ruled McKeone misappropriated $481,490.33 during his five-month tenure as Head of Finance at Rocket Brands.In March last year, the Supreme Court heard McKeone blew the cash on an epic booze, drugs and gambling spree, and was allegedly ‘sleeping in the work toilets’.He was also taking excessively long lunch breaks and frequently leaving the office without completing his duties, the court heard.McKeone was ordered to pay $556,698.50, including interest and costs, after it was found he had breached his contract and fiduciary duty, causing the company damage.He was not in court to hear the allegations, having apparently vanished, which sparked concerns for his well-being when he could not be located. He went on to have a whirlwind romance with Bachelor star Tahnee Leeson, but the pair split on the ‘evening of Mother’s Day’ in 2025, just weeks after welcoming their son Arlo However, the Mail revealed McKeone had actually moved back to his home state of Western Australia, where he was found safe and well.A year after the Supreme Court ordered McKeone to repay the money, it emerged he was being pursued for the debt in the Federal Circuit Court.Last year’s orders coincided with the conclusion of a lengthy police investigation, which saw McKeone charged with more than 100 offences related to obtaining financial advantage by deception from his former employer.Rocket Brands lodged a creditor’s petition seeking ‘a sequestration order… against the estate of Justin McKeone’ for the full amount of the Supreme Court judgment, plus an additional $63,346.02 in interest, The Age reported.The petition claimed McKeone was served with a bankruptcy notice on March 20 and had failed to comply with the requirements of the notice by April 10.It was heard in the Federal Circuit Court on August 6, with Registrar Tim Whitehead legally declaring McKeone’s estate bankrupt.Mr Whitehead also ordered McKeone’s estate to pay $8,277.70 to cover Rocket Brands’ creditor’s costs.Associate Justice Ian Irving had previously stated McKeone had an obligation to repay Rocket Brands.’None of these transactions were authorised or approved by Rocket,’ Justice Irving said.’Mr McKeone admitted that he had stolen the money at a meeting with Mr [Matthew] Holmes, sole director of Cozmic Sales Pty Ltd, held on October 14, 2024.’Mr McKeone’s bank statements show that on each occasion he received the money he misappropriated from Rocket, he used the money almost immediately for his own personal purposes.’The court was told McKeone joined Rocket Brands in March 2024 on a $200,000-a-year salary.But just weeks into his probationary period, staff raised concerns about his erratic behaviour.Records showed McKeone had just over $1,000 in his account when he was accused of taking more than $6,000 in his first four thefts from his bosses.Barrister Kieren Hickie, for Rocket Brands, described it as a ‘spending spree’ which did not end until McKeone’s erratic behaviour sparked the owner’s investigation into the company’s finances.'[He’s] going on a spending spree for his own personal purposes, depleting his account down to nearly zero,’ he said.McKeone’s boss reported the alleged theft to Victoria Police on October 14, 2024, sparking a 15-month criminal investigation.
