Bindi Irwin has paid a heartfelt tribute to her late father Steve Irwin on the 12th anniversary of his death.

The 20-year-old daughter of the 'Crocodile Hunter' star - who was killed by a stingray whilst filming one of his documentaries on the Great Barrier Reef, near Queensland, Australia, in 2006 - shared a childhood photo of her with her father, mother Terri, 54, and brother Robert, 14, on Instagram on Tuesday (04.09.18) in the 'Happy Feet' star's memory.

Bindi - who was just eight when her dad passed away, aged just 44 - simply captioned the photo: ''Together Forever (sic)''

Earlier this year, the legendary conservationist was honoured with a star on the Hollywood Walk of Fame, and Steve's eldest child was delighted after hearing the news.

At the time of the announcement, she shared a throwback photo of herself and her dad giving a thumbs up sign.

She captioned the image: ''I am beyond excited to share with you all that we have just received the news that Dad will be honoured with a star on the Hollywood Walk of Fame.

''Dad changed the world by reaching out to people through their television screens to bring them on the adventure of a lifetime. To have his name on a Hollywood Star means the world as we carry on his important work (sic).''

And speaking at the ceremony, Bindi revealed the family have done al they can to carry on Steve's legacy in the natural world.

She said: ''We try to continue dad's legacy each and every day and we want to make sure everything he lived and died for continues on into the future.

''I have to tell you that I never in my wildest dreams imagined that this would become a reality and this is such an honour as a family.''
