Macron thanks PM's 'delicious wife' Lucy Turnbull

The French famously love food and romance and President Emmanuel Macron managed to combine both when he accidentally thanked Prime Minister Malcolm Turnbull and his "delicious wife" Lucy.

After a morning of speeches, meetings and greetings, Mr Macron fronted the media for nearly an hour on Wednesday afternoon alongside the Australian PM.

He switched mostly flawlessly from French to well-spoken English as he was quizzed by reporters from both countries.

But at the end of proceedings, Mr Macron proved it's not so easy to give a press conference in your non-native language.

The president had to rush off to a lunch with the French community, Mr Turnbull noted.

"For the French gastronomy, for the French wine," Mr Macron replied.

He continued: "Thank you and your delicious wife for your warm welcome. It was the perfect organisation of this trip. Thanks to you and Lucy."

The word for delicious in French - delicieux - also translates as "delightful".

The seemingly-hungry president earlier picked up on an analogy Mr Turnbull used repeatedly about "big fish, little fish, and shrimps" in reference to rules-based international order, noting he was a "big fan" of shrimps.

"Especially New Caledonian shrimps," he joked, ahead of his trip to the French territory on Thursday.

Mr Macron arrived in Australia on Tuesday night and kicked off his brief tour with a visit to the Sydney Opera House.

The 40-year-old shared dinner and wine with Mr and Mrs Turnbull alongside politicians, business leaders and others.

The French leader's wife, Brigette, hasn't travelled with him to Australia after their recent trip to the United States.

His slip-of-the-tongue caused a stir on social media with the moment trending on Twitter in Australia.
