To mark Steve Irwin Day, held annually on November 15, his daughter Bindi Irwin posted a heartfelt message for her Dad on Instagram. Underneath a photo of the pair enjoying a sunset, Bindi wrote, “Your legacy will live on forever. I love you for even longer.”

Younger brother Robert also posted tributes to his Dad to mark the occasion. Underneath a photo of Robert, Bindi, and Steve, Robert wrote, “Today is #SteveIrwinDay. Thinking a lot about my Dad today and the impact that he made on our planet, inspiring an entire generation. I also think about what a truly amazing dad he was.

“Through a lifetime captured on camera and stories from my family and those who knew him best, I’m able to remember the special times with dad. I still look up to him every day and while I miss him so much, it means the world to me and my family that each year we can have a day for the world to celebrate what he stood for❤️”.

Bindi commented on the photo, “Love you so much”.

Robert posted another tribute later in the day, thanking supporters for celebrating Steve Irwin Day. His second post read, “Wanted to say a big thank you to everyone who celebrated Steve Irwin Day today. It means the world to see so many people sharing stories and memories of how my dad changed their lives and inspired them. It is the honour of my life to get to continue his mission ❤️”.

Other tributes included one from the Australian Embassy in the United States, where Steve Irwin became incredibly popular thanks to his Crocodile Hunter series. Their tweet read, “Throw on your best khaki today as we celebrate Steve Irwin Day. Steve created a legacy inspiring people to love all wildlife, no matter how big, small, fluffy or scaly. So let’s all take a page out of Steve’s book today & appreciate & be kind to every living thing 💚🐍🐊🐨”.

Wildlife Warriors Worldwide, the non-profit organisation established by Steve and wife Terri, also posted in honour of the special day. Their Instagram post, accompanied by a photo of the entire Irwin family, read, “Today, we are celebrating Steve Irwin Day by honouring the most extraordinary Wildlife Warrior that ever lived. Steve’s passion and enthusiasm to conserve wildlife inspired countless others, people just like you, to fight for the protection of wildlife and wild places. 🙌🏻

Join us as we come together and continue Steve’s important conservation work by educating and connecting people with wildlife, in the hope that one day humans and wildlife will live harmoniously alongside each other. We’re all #WildlifeWarriors, and we are proudly wearing our khakis today. 💚”

Steve died in September 2006 after being injured by a stingray, leaving behind wife Terri, Bindi, 8, and Robert, 2.
