Robert Irwin has shared a touching tribute to his dad Steve, 20 years on from his death ❤️⁠ ⁠ The 22-year-old posted a childhood photo of himself looking up at his dad, alongside the simple message: “Your legacy is forever.”⁠ ⁠ Robert was just two years old when Steve died aged 44 on 4 September 2006, while Bindi was eight.⁠ ⁠ Both have since followed in their dad's footsteps, dedicating much of their lives to wildlife and conservation alongside their mum Terri at Australia Zoo.⁠ ⁠ Bindi also marked the anniversary with an emotional tribute, revealing her five-year-old daughter Grace watches Steve's documentaries every morning and knows the grandfather she never got to meet as “grandpa crocodile”.⁠ ⁠ She wrote: “I always thought that my dad's legacy is wildlife conservation; it turns out, his legacy is love.”⁠ ⁠ 20 years later and his impact is still being felt around the world ❤️⁠ ⁠ #steveirwin #robirwin #ladbible⁠
