Bindi Irwin remembers her 'hero' Steve Irwin on the tenth anniversary of his death.

Ten years ago today, Australian icon Steve ‘Crocodile Hunter’ Irwin was killed when a stingray barb pierced his chest.

On the anniversary of his death – which also happens to fall on Father’s Day this year – Bindi Irwin has paid tribute to her late father in an emotional Instagram post.

"You'll be my hero for my entire existence," she wrote alongside an image of her father holding her into the air for the camera.

"I love you more than words can describe."

Bindi - who turned 18 in July - regularly posts throwback pictures of her father for her fans, sharing that he inspired her love of animals and wildlife conservation.
