During its six-month stint in Melbourne the restaurant has delighted some 15,000 adventurous diners with offerings such as snail porridge and bacon and egg ice cream.
The dozens of staff who relocated to Melbourne for a limited residency at the Crown resort, while the flagship Fat Duck in Britain was being refurbished, are now preparing to fly back.
"To say it has been a journey is an understatement," said Heston Blumenthal to staff at their final service briefing this morning.
"This might be quite an emotional day for me."
Today does not just mark the end of a ten year long project. It also marks 20-years since the original restaurant in the British village of Bray opened.
Melbourne feeds a "creative explosion"
"Melbourne has been probably the catalyst for the biggest creative explosion that I have had in certainly 10 to 15-years".
The celebrity chef says his decision to open a pop-up venture in Australia has re-energised staff and himself.
"Melbourne has been probably the catalyst for the biggest creative explosion that I have had in certainly 10 to 15-years," he said.
"I've spent a massive chunk of time in the developmental kitchen trying to free my head-space up. And my creativity in the last six months has just gone 'bang'."
The chef feared staff would be seduced by Australia and that many would decide not return to Britain.
But he didn;t need to worry.
"I can't see how we could have moved to a better place, with better people, with better produce. Better everything really".
Just a handful are leaving the team. Some due to visa contraints and others to stay on with family.
"I can't see how we could have moved to a better place, with better people, with better produce. Better everything really," he said.
This is not the end of the celebrity chef's association with Australia.
Dinner by Heston Blumenthal will take over the space and open in late October.
