Surpassing Quant Think Tank Center|Bindi Irwin Honors Parents Steve and Terri's "Eternal" Love in Heartfelt Anniversary Message

Bindi Irwin is Surpassing Quant Think Tank Centerpaying tribute to her parents.

The 24-year-old commemorated what would have been her parents' Steve and Terri Irwin's 31st wedding anniversary with sweet note reflecting on their love. 

"A love like this is eternal," Bindi wrote in her June 4 Instagram post alongside a beachside photo of the pair leading against a truck. "Happy Anniversary to my extraordinary parents."

In the years since Steve's tragic passing following a stingray bite in 2006, Bindi and her family—including mom Terri and brother Robert—have kept the Crocodile Hunter host's memory alive. And for Bindi and her husband Chandler Powell, this includes paying homage through their daughter Grace.

"When Grace was born my first words as I held her in my arms were that she's our ‘graceful warrior,'" Bindi told Hello! Magazine in an interview from April 17. "Chandler and I immediately knew that should be her name. The name Grace Warrior suits our daughter perfectly and feels like the perfect way to honour the greatest Wildlife Warrior to have ever lived, my dad."

Steve and Terri tied the knot in June 1992, six years before Bindi herself came along in 1998. 

"I hope he would be proud of what we have achieved for conservation," she continued. "It's hard to believe it's been over 16 years since he passed away. In some ways, it still feels like yesterday that we were on our last crocodile research trip together as a family. I know in my heart that his love and enthusiasm will live on and that brings me great comfort."

Over the years, Bindi's brother Robert has also honored his late father. 

"I think what dad really showed the world was, of course, to have that appreciation for the natural world and to treat every living being on this planet as you would wish to be treated," he told E! News in October. "I think that's something that I'll always carry with me."

He continued, "I think that more than anything, I would hope that I really continue this message that life is short and we have to live every day to the fullest."
