Although Father's Day is celebrated in North America in June, it was just this past Sunday, September 1st in Australia. To celebrate the holiday, Bindi Sue Irwin posted a sweet tribute to her late father on social media.

Famed conservationist and television personality Steve Irwin died when Bindi was just 8 years old, and the now 21-year-old has followed in her famous father's footsteps by continuing his conservation work at The Australia Zoo. Bindi posted a sweet throwback video on her Instagram featuring old home movies of herself, her dad and mom Terri in remembrance of her dad on Father's Day. "It’s Father’s Day here in Australia," Bindi captioned the video. "Reflecting on these wonderful moments. Hug the people in your life who bring light to your heart and always remember that love lasts forever."

The video shows Steve playing with his daughter as a baby, and other clips of him, Terri and Bindi simply enjoying time together. It's a sweet tribute to her father that was gone far too soon.

Today is also the 13th anniversary of Steve's death. He was killed after being attacked by a stingray while filming a movie on location, and Bindi posted a sweet picture featuring a quote from Winnie the Pooh to mark the occasion. "If there ever comes a day when we can't be together, keep me in your heart, I'll stay there forever," read the quote.

Last month on her 21st birthday Bindi got engaged to her longtime boyfriend, Chandler Powell, and she revealed to Entertainment Tonight that her brother, Bob, will be the one to walk her down the aisle to honor her late father. "I think that for me, it'll be really important that Robert walks me down the aisle," Bindi said. "That's something that I really want to do. I'm always so grateful that Robert is there, and he has been such a big part of my life and he's always stepped up and been the one to give me a hug when I need it and encourage me forward in life," Bindi said. "So he will definitely be the one to walk me down the aisle when the time comes, and I think that will make it really special. And I think that's what dad would have wanted as well," she added.

She also revealed that she'll share the traditional father/daughter dance with her mother, Terri.  "So I think, when the time comes, Robert will walk me down the aisle, [Chandler and I] will have our wonderful moment and I'll have my dance with mom. I think that would be wonderful."
