In August 2016, Guillaume opened his own Bistro Guillaume in Sydney’s CBD. When Crown Sydney opened its doors in late 2020, Guillaume was appointed as Culinary Ambassador, building on the partnership and relationship with Crown that now spans 11 years.
Guillaume joined the board of the Bestest Foundation in 2008. The Bestest Foundation is a national charity established to help children in need who might otherwise ‘fall between the cracks’. At each Gala Dinner, Guillaume will gather 40 of his chef friends and colleagues from all over Australia to cook together for one night.
This event has enabled the charity to raise over $7million dollars with the funds raised going directly to the almost 4,000 children who have become part of the Bestest family for their specified purpose.
In late 2014, Guillaume was a recipient of the Chevalier de l’Ordre National du Merite (Knight of the National Order), a prestigious honour endowed by the French government for outstanding services rendered to France in Foreign Affairs and International Development.
In 2015, Guillaume was named Chef of the Year at the annual GQ Men Of The Year awards. Guillaume is currently an ambassador for Audi Australia.
Guillaume is the host of SBS’s food series, Plat du Tour which airs during the coverage of the Tour de France.
Guillaume takes viewers on a tour of great French cooking during the 21 recipes that originate from different regions of France and correlate to the different Tour de France stages.
