Forever in their hearts. Bindi Irwin and Robert Irwin have paid tribute to their father, Steve Irwin, many times in the years since his heartbreaking death. Steve - a wildlife conservationist and beloved television personality - died at age 44 after being pierced by a stingray barb in September 2006. He was survived by his children and his wife, Terri Irwin. Although Bindi and Robert were only 8 and 2 at the time of their father's passing, they've grown to carry on his legacy in ways both big and small. Today, the family continues to run the Australia Zoo, which Steve's parents started in the 1970s. They have also honored Steve during important moments in their lives, such as Bindi's wedding to Chandler Powell in 2020 and Robert's Dancing With the Stars debut in 2025.
