Bindi Irwin paid an emotional tribute to her late father on Tuesday as she joined her family to celebrate ‘Steve Irwin Day’.

The late Crocodile Hunter’s life and legacy are remembered each year on November 15 at the Australia Zoo in Queensland, which is owned by his wife Terri.

At the event 18-year-old Bindi fed a giant crocodile, while her 12-year-old brother Robert held a much smaller version.

On the day guests were encouraged to where khaki in honour of Steve.

Later she shared more photos of her father on Twitter and wrote: “Khaki and the happiest memories. #SteveIrwinDay.”

Bindi was just eight-years-old when her father was killed following a stingray attack. Last year she competed on, and won ABC’s ‘Dancing with the Stars’ with partner Mark Ballas.

Speaking about ‘Steve Irwin Day’ to the Sunshine Coast Daily newspaper, Bindi’s mother Terri said: “Steve Irwin Day is such an incredible event that we hold each year together in honour of Steve, celebrating everything he was so passionate about – family, conservation and having fun.

“He touched the lives of so many people and his important message of conservation is something everyone can be passionate about.”
