Robert Irwin photobombs sister Bindi and her husband Chandler Powell while on holiday in Tasmania

He’s the adventurous younger brother of pregnant Bindi Irwin.

And on Sunday, Robert Irwin, 17, revealed himself to be quite the prankster while his famous family holidayed in Tasmania. 

Bindi uploaded a picture of the budding photographer photobombing her and husband Chandler Powell while touring the Apple Isle. 

‘Robert, you always make photos that much better. Love ya!’ she captioned the post, alongside a laughing face emoji.

In the picture, the teenager was spotted making a funny face while popping his head to the side and into the frame of of his sister’s photo with her 24-year-old husband.

Rob’s lips are pursed as he stares directly down the lens of the camera, while Bindi and Chandler smile sweetly in the background. 

The image of the trio in bushland was then shared by the cheeky teenager to his account, along with a series of other pictures of them holidaying with their 56-year-old mother, Terri.

‘Just got home from a wonderful trip to Tasmania to ring in the New Year – such a gorgeous spot! (Part 1 of our adventures),’ he captioned the post.

They appear to have gone hiking, with the family visiting mountain tops and walking along ocean clifftops.

Rob also uploaded a few short videos of himself visiting the beach on foot and bike.

Their trip follows Rob revealing two hobbies which helped him escape the ‘craziness’ of 2021 on Friday. 

‘This year I discovered a love for guitar and painting – a beautiful escape from the occasional craziness that this past year brought,’ he wrote on Instagram.  

Rob’s new hobbies are two of many – adding to his interest in skateboarding, photography, surfing and caring for animals, just like his late father, Steve Irwin.
