Wildlife warriors are not just for the faint of heart! 

Steve Irwin‘s son, Robert, celebrated his coming of age with an “epic 18th party” with his family and friends at Australia Zoo on Wednesday, Dec. 1. 

Mom TerriSister Bindi Irwin In honor of the 18th of their birthdays, we joined the photographer to have a fun day at the Zoo.

Bindi, 23 years old, wrote on Instagram that she was happy 18th of the greatest. His relationship with their 8-month-old daughter has been called “This year you have been promoted to uncle” Grace.

Bindi said, “I cannot wait to see the incredible adventures that are on your horizon,” I’ll be there for you always (with a full fridge). We love you. Robert responded in true older brother fashion: “Thanks B!” We love you and your fridge fully stocked so much. 

He celebrated his day by unveiling new statues of three different wombats at Australia Zoo. Meanwhile, guests participated in clay workshops, a photo station, pony rides and more activities.
