Photographer, sculptor and installation artist Boltanski has said the deal with the Moorilla winery, brewery and restaurant owner gives him an ongoing fee until he dies.
The 65-year-old artist told the French press agency AFP recently: "This man (Walsh) thinks he can beat the odds and he says he never loses. Anyone who never loses or thinks he never loses must be the devil."
His payment increases with each passing year, so to make the venture financially worthwhile, he must live for another eight years.
