The couple, both 19, recently enjoyed a trip to New York City together, with Rorie sharing a loved-up post on social media on Monday.
“R&R take on NYC!!” she captioned the live photo.
The black-and-white snap shows the pair cuddling close together as they pose for a selfie with the city’s iconic skyline behind them.
Fans were quick to notice that Robert had shared a comment underneath Rorie’s post that said: “I love you!!!”
Robert’s mum Terri Irwin also wrote, “You two are so sweet!”, while Rorie’s sister Scarlet added, “You guys”.
While some followers made jokes about how it was their dream to go on a holiday with Robert, a majority of commenters wished them well in their relationship.
“You two are the cutest,” one person replied, followed by another who said, “So happy for you both”.
“So adorable, hope you guys are having the best time!” a third shared, with someone else writing, “Y’all are the most gorgeous & sweetest couple ever”.
Rorie has posted a handful of snaps with Robert on Instagram over the past month, including a gallery of snaps last week painting together on holiday and enjoying a cheese board.
She also shared a photo of herself and Robert releasing a sea turtle that was rehabilitated at the Australia Zoo Wildlife Hospital back in the ocean, which he commented was the “best day ever”.
The couple made their red carpet debut at the Sydney premiere of Mission: Impossible – Dead Reckoning Part One in July.
Who is Rorie Buckey?
Rorie is the niece of the late Australian actor Heath Ledger and currently studies at a university in Western Australia.
While it’s unknown how long the pair have been dating, it was reported last month that Robert was planning to leave Australia Zoo and relocate from Queensland to WA to spend more time with her.
“It’s a real pain,” a source told Woman’s Day. “Right when they really want to explore their relationship, they have this hellish distance between them.”
