Jamie's Italian Parramatta has become the second victim of the restaurant group's collapse, unexpectedly shutting its doors on Monday after its new management failed to reach a rental agreement with the site's landlord.

The Jamie Oliver Restaurant Group (Australia) Pty Ltd collapsed in April, less than a year after the celebrity chef made an appearance down under to relaunch the six restaurants operating under his name – and not long after it had been revealed his UK operation was floundering in debt.

The Canberra restaurant closed immediately.

As the company was placed into voluntary administration, its other five restaurants – in Sydney CBD, Parramatta, Brisbane, Melbourne and Adelaide – received a lifeline from the Brisbane-based Hallmark Group.

But Hallmark, which is best known as the owner of Brisbane Irish pub Finn McCools, appears to be struggling to take control of the Jamie's Italian empire's Australian arm.
