An administrator could be forced to offload unprofitable outlets, while some venues could be offered to existing operators. Calombaris, who left his role as a star judge on MasterChef last year, did not respond to requests for comment on Sunday. The fate of 18 restaurants and fast-food outlets remains unclear. These include Melbourne CBD venue Gazi, souvlaki chain Jimmy Grants, Yo-Chi frozen yoghurt stores and Calombaris' flagship fine dining establishment, Press Club, which became Elektra Dining in October.

Loading In December, Hellenic Hotel in Williamstown was relaunched as Hotel Argentina, while Hellenic Kew transformed into an Italian restaurant, Vita. Hellenic Republic in Brunswick East re-opened as Crofter Dining in mid-January. The potential voluntary administration comes just seven months after Made Establishment was ordered to make a large contrition payment as part of an unprecedented deal with the Fair Work Ombudsman, for underpaying $7.83 million in wages to 515 current and former employees. All former and current staff were reimbursed. At the time, facing a vicious backlash on social media, Calombaris told the ABC he was "gutted" and took full responsibility for the scandal, but vowed to maintain his embattled empire and protect hundreds of jobs. "We aren't closing our restaurants, we're here. And it's my job as their leader to keep pushing forward and keep speaking this message, not shying away from the mistake we made, but also acknowledging that we fixed it," he told the 7.30 program.

"I won't forget that afternoon in 2017 when we sat there with my new business partners after we'd done a full audit for the business and discovered the underpayments." Multimillionaire Radek Sali, the former chief executive of Swisse vitamins, made an ill-fated foray into the hospitality industry when he took a major stake in Calombaris' restaurants in 2016. However, within months a string of payroll discrepancies were identified and the Fair Work Ombudsman opened a major investigation. At the time, Mr Sali said he was "prepared for a few potholes in the books" when he first invested, but was unaware that hundreds of staff had been ripped off. The uncertain future of Calombaris' eateries, comes just a week after The Age and The Sydney Morning Herald revealed that Dinner by Heston had been consistently underpaying staff since 2015, when it opened in Crown casino. Tipsy Cake, the company that owns the Melbourne-based Dinner by Heston and is based in the Caribbean tax haven of Nevis, entered voluntary liquidation in December.
