Robert Irwin and girlfriend Rorie Buckey pack on the PDA as he visits her in Perth

Robert Irwin’s romance with Rory Buckey, Heath Ledger’s niece, takes off whether his protective mother Terri likes it or not.

The young couple have been in a long-distance relationship for about seven months and were spotted enjoying a very amorous reunion at Perth Airport on Friday.

Robert, the 19-year-old son of Aussie TV legend Steve ‘The Crocodile Hunter’, had flown in from his hometown in Queensland to spend the weekend with Rorie, 18, and her family in Perth.

Rorie waited for Robert at the airport and hurried to wrap her arms around him. He left the plane.

Robert looked decidedly in love, closed his eyes as he grabbed the pretty blonde by the waist and pulled her towards him.

Robert looked delighted as he pulled his suitcase to the exit before piling his belongings into the back of a parked car.

The wildlife photographer clearly went out of his way to impress his girlfriend during their reunion, swapping out his khaki zookeeper uniform for a tight navy T-shirt and black skinny jeans.

He completed his look with sneakers, a stylish wristwatch and a black face mask.

Robert and Rorie have a lot in common; both grew up in the public eye after the devastating loss of a family member.

Heath was at the peak of his Hollywood career when he was found dead in January 2008 of an accidental drug overdose.

Robert’s father Steve Irwin, known to the world as the “Crocodile Hunter,” died at the age of 44 on September 4, 2006 after being stabbed in the chest by a stingray.
