Bindi Irwin Pens Sweet Tribute To 'Greatest Dad' Steve: 'I Love You'

Bindi Irwin remembers her late dad on his birthday.

Steve Irwin has been gone for nearly 16 years, but he’s not forgotten. His daughter is sharing a sweet throwback with her dad on his birthday.

The famous Australian zookeeper died in September 2006 after being accidentally pierced in the chest by a stingray barb while filming in the Great Barrier Reef.

The conservationist and zookeeper posted a heartfelt tribute on Instagram to the "greatest dad" who was taken from this Earth far too soon at age 44.

"Happy Birthday to the greatest dad and Wildlife Warrior," Bindi began.

"Today I’ll watch ‘The Crocodile Hunter’ with Grace Warrior and share stories about her incredible Grandpa Crocodile," she continued.

Bindi concluded her message, writing, "I love you with all my heart. Your legacy lives on."

The touching tribute seemed to hit a chord with Bindi's 4.8 million followers. In just less than a day, the post racked up almost 331,000 likes and over 2,700 comments.

"'Heroes never leave, they live on forever in the hearts and minds of those who would follow in their footsteps' He lives on through you and your family and lights this world with the same effervescence he will always have!" actress Emmy Perry commented.

"The crocodile hunter was my favorite show as a kid and your dad's legacy is so beautiful. I didn't know until now that we also share a birthday," added another follower.

"Yes it does. It lives on through you, your mom, your brother, and your daughter. You are so inspiring to me and everyone. Thank you for sharing stories with us," remarked the third user.

"Happy heavenly birthday to a beautiful soul that brought love, passion, education, rightnessous, respect, equality, and much more to this world!!!!" a fourth comment read.

On November 15, Bindi celebrated "Steve Irwin Day" by sharing a lovely picture of the father and daughter.

"Your legacy will live on forever. I love you for even longer," she captioned the share. "November 15, Steve Irwin Day."

As of this writing, the post earned more than 597,000 likes and about 3,900 notes.

Steve is survived by his wife Terri, 57, daughter Bindi, and son Robert, 18.

Bindi is married to Chandler Powell, 25, and shares an 11-month-old daughter named Grace Warrior.

In January, she showed off her new tattoo on her forearm, which reads, "Graceful warrior," on Instagram.

"The words I spoke to our daughter as I held her for the first time in my arms were, 'My graceful warrior,'" Bindi wrote in the caption.

She went on to explain that she used her dad's handwriting to make it even more special.

"That’s how her name was born. This is my dad’s handwriting to keep him with me, always," she shared. "Our dear alligator, Daisy, is next to these words to represent our conservation work as Wildlife Warriors. And my beautiful wedding ring in bloom. Validation every day of the three most important things in my life: family, purpose and unconditional love. ❤️ Since Grace’s breastfeeding journey ended, now felt like the perfect time for this empowering artwork."
