Robert Irwin pays touching tribute to his late father Steve Irwin with sweet video compilation

Last September marked 15 years since beloved Australian wildlife expert Steve Irwin passed away.

But that wasn't stopping Robert Irwin from paying a touching tribute to his late father for Father's Day in America.

Taking to Tiktok, the conservationist shared a sweet video montage of beautiful moments he shared with Steve and his sister Bindi prior to the Crocodile Hunter's death.

Alongside the video, the 18-year-old wrote: "I had the best dad in the world. Thinking of him and remembering nothing but fun times.

"I hope you all had a wonderful Father’s Day in the US – sending love to those who couldn’t celebrate with their Dad."

Bindi and her brother, who were just eight and two years old respectively when their famous father died, have worked tirelessly alongside their mother Terri to honour their father's wildlife warrior legacy.

Steve Irwin died on September 4, 2006, after being struck by a deadly stingray barb while filming for one of his many TV shows off Port Douglas in North Queensland, and left a family, a nation, and the world in shock.
