The 19-year-old star took to Instagram on Sunday (03.09.17) to celebrate the Australian version of Father's Day, and posted a touching video in memory of the late conservationist who tragically died in 2006 at the age of 44, after he was pierced in the chest by a stingray whilst filming a nature documentary.

The footage Bindi posted was taken from another of Steve's documentaries, in which he talks to a three-year-old Bindi about the dangers of bull ants.

Bindi captioned the video: "Remembering these days. This is a 3 year old Bindi helping out with Dad's documentary filming. Life is always changing and evolving and I'll always be thankful that I learned so much from my dad. He taught me to treat every being on Earth the way you would wish to be treated. From the tiny ants to the enormous elephants. We are all connected and must respect each other to live in true harmony. I'll forever be thankful to have had these values passed on to me. Happy Australian Father's Day

"May your heart be full and your day be filled with the ones you hold dear. Here's to unconditional love and happiness beyond compare. (sic)"

Bindi's brother Robert also posted on Instagram in memory of his father - who was nicknamed The Crocodile Hunter - as he shared a snap of himself as a young child on a swing being pushed by Steve.

He wrote alongside the photo: "This #FathersDay in Australia remembering the best dad in the world. He was all about family and fun and I hope to dedicate my life to honouring his legacy. (sic)"

Monday (04.09.17) also marks the 11th anniversary since Steve's passing, where his two children are expected to pay further tribute as they have on previous years.
