To mark the occasion, the wildlife photographer spent the day at Australia Zoo in Queensland with his mother, Terri.

The pair were all smiles as they unveiled the zoo’s new statues of the extinct Australian marsupial, the Diprotodon.

The mother-son duo posed for several photos while unveiling the Diprotodon statues, and also spoke to several media outlets. 

Robert – who is the spitting image of his late father, Steve ‘The Crocodile Hunter’ Irwin – was dressed in Australia Zoo’s signature khaki uniform.   

Steve Irwin died in September 2006 at the age of 44 after being pierced in the chest by a stingray barb while filming a documentary in Batt Reef, Queensland.
