Bindi Irwin celebrates her parents’ love.
On Sunday, the 24-year-old conservationist celebrated the 31st wedding anniversary of her father, the late “Crocodile Hunter” star Steve Irwin, and her mother Terri Irwin, 58, in a sweet Instagram post.
“Such love is eternal. Happy anniversary to my extraordinary parents,” Irwin captioned the commemorative photo, which shows Steve and Terri hugging while standing by a truck on the beach.
Irwin’s mother is pictured smiling for the camera while her husband – who died in 2006 after being stung by a stingray in Australia’s Batt Reef – rests an arm against the door of the truck. Although it’s unclear when and where the photo was taken, the couple lived together in Australia for 14 years after tying the knot in June 1992.
It’s not the first time mother-of-one Irwin has publicly celebrated her parents. On Mother’s Day in May, she shared another old family photo with the caption, “Happy Mother’s Day to my beautiful, strong, kind, loving and caring mom. I’m grateful every day to share this adventure of life with you.”
This time, the adorable snap appeared to include Irwin himself, who was being held in a car by her mother while her late father displayed his famous animal-handling skills and entertained his daughter with a tawny frogmouth.
Irwin has previously expressed her excitement about becoming a mother herself after giving birth to her first child, daughter Grace Warrior Irwin Powell, in March 2021.
In June 2021, she told PEOPLE about the “extraordinary” bond she’s already formed with her newborn. “When we first brought her home, it was like she was always with us,” she told PEOPLE. “It’s a really strange feeling when you can’t remember what life was like before this beautiful little human. I have never experienced such love.”

In May the Damned! It’s the Irwins star also told PEOPLE about her daughter at a gala dinner honoring her late father
“She just loves wildlife and is so excited to learn more,” Bindi said at the event at the SLS Hotel in Beverly Hills, California. “She knows so many animal names. This is unreal. I mean, I guess it runs in the family.”
Noting that Grace’s “favorites are dinosaurs now,” the proud mom continued, “She just talks about all these different dinosaur names that we don’t know how she knows all of them.”
Bindi added: “It’s really remarkable to see how passionate she is about nature.”
