Advisory and investment firm KordaMentha has been appointed as administrators of 22 companies in the Made Establishment Group.
Calombaris added the last few months have been the most challenging for him.
“At this time, while personally devastated, I remain thankful to my family, friends, the MADE team, our loyal and regular customers,” he wrote.
I am so sorry all our collective efforts have not proved to be enough. I’m gutted that it’s come to this.
“The one thing I would ask is that you please respect how difficult this is for my team, my family, myself and those close to us and simply allow us to go through this process which is already deeply affecting us all.”
The news comes as Calombaris’ family property in Melbourne’s affluent Toorak was listed for sale.
Made Establishment group employs about 500 staff at its 18 restaurants.
The collapse comes after it emerged last year staff were backpaid $7.8 million in wages and superannuation in 2017.
