He has been invited to dance at international ballet galas in England, Denmark, China, Dominican Republic, Uruguay, Indonesia, Russia, Mexico, Argentina, Brazil, Ethiopia, Colombia, Japan, Australia, the United States, Hungary, Canada, Peru, Paraguay and Switzerland – where he was one of the winners and an apprenticeship recipient at the 2009 Prix de Lausanne. Vinet also was a recipient of the Premio Jovenes Líderes del diario El Mercurio (2009) – an award to Chilean artists, presented by the ambassador of Chile in the United States. Vinet appeared as a special guest dancer at the 2009 Grammy Awards and holds a parallel career as a model, appearing in campaigns for brands like Armani, Burberry, Newman and Dolce and Gabbana, and has been featured in Vogue.
In 2017 Vinet was the artistic director and creator of the first international ballet gala to be presented at the emblematic theater in Chile Teatro Oriente. In 2018 he was mentioned in Dance Australia as one of the best performances of the night during the premiere of FORTE in Melbourne, Australia and in 2020 he directed and founded the digital show interMission, a production filmed in three continents gathering some of ballet’s biggest stars all coming together digitally to raise funds for the international charity Save The Children. Most recently, Vinet was honored to be a 2020 Prix de Lausanne competition jurist in Switzerland and in 2022 for Youth American Grand Prix, Danza Activa in Panama and Icon Dance awards, being the youngest person in the history of these prestigious competitions to be invited to join the panel of judges. Sebastian is currently a principal guest dancer with Utah Metropolitan Ballet, Ballet Idaho and Australian National Youth Ballet, also performing at several international ballet galas and dance events as well as teaching masterclasses at the top ballet schools in the world, teaching experiences that have inspired him to create a scholarship program called Bailarines del Manana, awarding over $40,000 USD in scholarships this past June in Chile and becoming the national pre selection for Youth American Grand Prix.
