The two have been best friends since Chandler started dating Robert’s sister, Bindi, 24, in late 2013, whom he later married in 2020.

It comes after Robert revealed the passion he and his late father Steve share.

In February, the nature warrior told Adelaide now that the men both have a deep love for the ocean.

‘From an early age I have always been involved with the ocean. It has always been my father who had a strong connection to the sea,” he said.

Robert went on to explain that his passion for photography is a way to carry on his father’s legacy.

Steve, known as The Crocodile Hunter, died on September 4, 2006, at the age of 44 after being gored in the chest by a stingray while filming a wildlife documentary called Ocean’s Deadliest in Queensland.

He is survived by wife Terri, daughter Bindi and son Robert, who was only two years old when Steve died.

The two have been best friends since Chandler started dating Robert's sister Bindi, 24, in late 2013, whom he later married in 2020.
