The once Naked Chef will open all four of his remaining Australian restaurant branches to host a free charity lunch for the less privileged in our community.

Restaurants in Sydney, Brisbane, Adelaide and Perth will be open from noon to 4:00 pm, with the event being alcohol-free.

In the call-out video, Oliver explained his intentions behind the event.

“We want to fill them with people that can come in for free, people that will be lonely, people that might be homeless, and people in need,” he said.

“For that, we are going to be working with local charities, my foundation which is The Ministry of Food in Australia which is an incredible set-up that I’m so proud of, with the help from The Good Foundation.

“We are also asking for volunteers, so for those people that would be interested, come down to Jamie’s Italian and volunteer,” he continues.

“It’s going to be loads of fun I promise you.

“If you know someone who is going to be lonely, or homeless we are going to spoil them.

“We are going to spoil them with beautiful food, comfort food, and loads of love, and we are going to laugh a lot.”

News of Oliver’s community venture comes at a troubled time for his business empire.

Jamie’s Italian ran into financial trouble last year when it faced bankruptcy in September.

In an interview with The Financial Times, Oliver revealed that the restaurant chain “had simply run out of cash”.

Oliver was forced to inject £7.5 million of his “personal savings” into Jamie’s Italian, supplemented by a further £5.2 million in the months that followed.

The Canberra and Parramatta branches in Australia were forced to close, while 12 of its 37 outlets in the UK were also shut, making about 600 staff redundant.

Jamie’s Ministry of Food will be inviting families in their networks to come in for lunch on Christmas Day.

Oliver is requesting 200 volunteers to help run the four eateries.

Volunteers must be 16 years and over, and will be required to assist with a number of jobs including table setting, food running, table clearing, dishwashing, playing Santa and welcoming guests on the day.

Experience in the hospitality industry is not required.
