Robert and Bindi Irwin share moving tributes to their late father on Steve Irwin Day: 'It's so wonderful that Dad's life and legacy is remembered'

Robert and Bindi Irwin have paid a moving tribute to their late father on November 15.

The date marks Steve Irwin Day in Australia, an annual event honouring the life and legacy of the conservationist known around the world as the 'Crocodile Hunter'.

The I'm a Celebrity...Get Me Out of Here star shared a charming throwback photo of himself posing with his dad.

In the snap a youthful Steve can be seen doting over his young son who is clutching at a toy while sitting in a 'tinny' boat which parked on the banks of a river.

'November 15 is Steve Irwin Day and it's so wonderful that Dad's life and legacy is remembered and celebrated on this day,' Robert said in the caption

For her special tribute, Bindi, 26, posted her own throwback picture in which she is featured as a toddler.

In the heartwarming snap Steve can be seen crouching beside her and holding a small snake by the tail up to her smiling face.

'It's Steve Irwin Day, and we're celebrating the life and legacy of the original Wildlife Warrior,' Bindi said in the caption.

'How incredible that one man changed the world, igniting a passion for wildlife conservation across the globe!'

Steve died on September 4, 2006, at the age of 44 after being pierced in the chest by a stingray while filming a documentary on the Great Barrier Reef.  

Following his death, Steve's family, including daughter Bindi, widow Terri, 60, son Robert, and son-in-law Chandler Powell, 28, have continued his conservation work at Australia Zoo.

It was Steve's father, Bob, 83, who built the iconic Queensland zoo from the ground up in 1970 and passed it on to his late son and his wife Terri in 1992.

In his lifetime Steve promoted wildlife conservation with his own hit TV show, the Crocodile Hunter.

And his family have carried on his legacy with their own blockbuster wildlife reality series Crikey! It's the Irwins, which debuted in 2018 and can still be seen on the Animal Planet network.

It comes after Bindi and Robert Irwin took to social media to share never-before-seen photos of their late father Steve to mark the 18th anniversary of his death in September.

Bindi posted a throwback photo of a young Steve holding a fully grown crocodile at Australia Zoo, and captioned it with some heartfelt words.

'It is an honour to help continue the work you started. Your legacy lives on,' Bindi began.

'In our family, our team, Australia Zoo, Wildlife Warriors and The Crocodile Hunter Lodge. Hope to make you proud.'

Robert also posted a jaw-dropping photo of his father holding a camera in a small boat on a river, as he enthusiastically filmed a crocodile lunging at him.

Robert kept the caption short and sweet, by posting a love heart and crocodile emoji.

Meanwhile, Steve's widow Terri, 60, shared a heartwarming tribute to her husband on Father's Day by posting two complementary photos of both Steve and two-year-old Robert holding huge native lizards.

'Steve had so much love for Robert and Bindi. He was the best dad. It warms my heart to see how much they always wanted to be just like him,' she wrote.

Bindi was six years old when he tragically passed, while Robert was three months shy of his third birthday.

His legacy, however, lives on through his family, who have continued his mission of wildlife conservation and advocacy.
