Robert Irwin, son of the late conservationist Steve Irwin, has been crowned this year's winner of Dancing with the Stars, a decade after his older sister Bindi won the same title. The popular US dancing competition sees stars paired with professional dancers to perform in front of a panel of judges, with the audience also voting on their favourite couple.

The 21-year-old was favoured to win, with strong performances over the show's 11 weeks, including a tribute to his father and a surprise appearance from his sister Bindi. With a legion of fans in the US, Irwin's finale had an Australian bent with one dance choreographed to a song by Australian rock band Jet.

During the three-hour finale, Irwin and his dance partner Witney Carson performed to songs by Avicii and Sydney-born Sam Sparro. They triumphed in the instant dance challenge – where Irwin and Carson were told the style and song just minutes before taking to the stage. Irwin, who competed despite a rib injury, beat fellow finalists including influencer Alix Earle and Olympic gymnast Jordan Chiles.

He broke down in tears after his final performance, expressing his desire to make his father proud. I wish he could see it, I really wish he could be here, he said. Steve Irwin was renowned for his wilderness adventures and was tragically killed by a stingray in 2006 while Robert was still a baby. Today, Robert is continuing his father’s legacy as a passionate advocate for wildlife.
