Steve would be proud: Robert Irwin is the spitting image of his late father as he celebrates his 17th birthday at Australia Zoo with his mother Terri

Robert Irwin looked all grown up as he celebrated his 17th birthday on Tuesday.

To mark the occasion, the wildlife warrior 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.

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

Terri wore a similar outfit, but she opted for a long-sleeved shirt and pants instead of a short-sleeved shirt and cargo shorts.

She styled her brunette hair into a ponytail and kept her makeup natural with flawless foundation and a touch of eyeliner.

‘Happy birthday to my amazing brother! Your kind heart and fantastic sense of humour makes my every day,’ she wrote in the caption.

‘Our baby girl is going to love her “funcle” (fun uncle) so very much. You’re one of the brightest lights the world has ever seen. I’ll always be here for you. Love you!’

Bindi and Chandler are expecting a daughter early next year.
