Bindi's touching tribute to dad Steve Irwin on his 57th birthday

She was just eight-years-old when her dad tragically passed away, and now Bindi Irwin has paid a touching tribute to Steve Irwin on what would have been his 57th birthday.

The 20-year-old took to her Instagram account to post an adorable snap of her as a baby in the arms of her proud and beaming dad.

In true Steve Irwin fashion, he can also be seen holding a cuddly koala on his other shoulder.

“Thank you for always being my guiding light,” Bindi captioned the throwback snap.

Google have also honoured ‘The Crocodile Hunter’s’ legacy by changing the Google Doodle to an illustration of the famous conservationist.

In the illustrations, a smiling Steve holds on to a crocodile, hangs out with his kids, Bindi and Robert, and stands outside Australia Zoo with his wife, Terri.

Steve, nicknamed ‘The Crocodile Hunter’, tragically passed away at 44-years-old in 2006, after being stung by a stingray while filming a documentary in Queensland.

Terri, Bindi and Robert have made sure his legacy lives on as they continue to share their love of wildlife with all of Australia and the whole world.

“We carry on as though he were still here and we treasure everything he stood for and carrying on with his important legacy,” Terri told Sunrise last year.

“I think it is true of anybody is great journey, you do have a choice, you can kind of curl up in the corner or do what you would have wanted you to be healthy and happy and carrying on with what you are passionate about,” she added.

“Conservation work really is and what we do, is really more who we are. I am proud to be carrying on where Steve left off and I do miss him every day. Today is a wonderful celebration and I am really enjoying it.”
