Irwin died in 2006 at the age of 44 when a stingray’s barb pierced his heart while he was diving near the Great Barrier Reef.

His children, Bindi Irwin, now 28, and Robert Irwin, 22, marked the anniversary with heartfelt posts; Bindi described her father as the family’s “superhero” and said his true legacy is love, while Robert shared a video of Steve speaking about passion and empathy.

Since Steve’s death, the Irwin family has continued to run Australia Zoo in Queensland, a wildlife park originally founded by his parents in the 1970s.

The family also oversees several conservation initiatives, including a crocodile research and telemetry‑tracking program, the Australia Zoo Wildlife Hospital that treats and releases injured and orphaned animals, and a dedicated wildlife rescue unit.

These ongoing efforts illustrate how a celebrated conservationist’s mission can shape his descendants’ values and inspire broader public engagement; Bindi even noted that her five‑year‑old daughter watches her grandfather’s documentaries every morning, feeling “utterly loved” by the man she never met.
