Three months later, Rob and Rorie made their red carpet debut, appearing at the Australia premiere of Mission Impossible: Dead Reckoning Part One in Sydney.
Then in August 2023, both Rob and Rorie "hard launched" their relationship with sweet photos together, confirming they were officially dating for the first time.
Whilst it's not crystal clear how Rob and Rorie met, or when exactly they started dating, fans are thrilled to see Rob find love, as are we!
Prior to being linked to Rorie, Rob was rumoured to be dating Lucia Field, the daughter of Blue Wiggle Anthony Field, after an image of the pair together at Australia Zoo was posted online.
The duo never confirmed or denied the relationship, but fans did go crazy to find out that the young Aussie heartthrob was off the market.
In the image, Lucia can be seen grinning as she tilts her head toward the young wildlife warrior.
But if our time estimates are correct, Rob was already dating his current girlfriend Rorie at the time, meaning he and Lucia were (and presumably still are) just friends.
Before Rob was ever linked to Rorie and Lucia, the rumour mill was abuzz that Rob was dating US actress Emmy Perry.
The two have been connected for years, but a July 2022 trip to Australia saw Emmy spend plenty of time at Australia Zoo.
Rob and Emmy were first spotted together in 2019 when they enjoyed a day at Disneyland and also attended the Steve Irwin Gala Dinner in Los Angeles where a source revealed that "sparks were flying between them."
Emmy, an animal lover who has begun her own animal charity, Emmy’s Hope, was said to be enamoured by Rob, and the two have remained close in the years since.
What has Rob publicly said about dating?
A fan of Rob’s made her feelings known on a visit to the zoo, which she captured in a video that quickly went viral.
"I think you're so cool and I was wondering if I could have your number,” the brave fan asked him.
"While I wasn't able to give out my personal details, I really appreciated having a conversation with someone who definitely had a great interest and passion for the Zoo and my message," Rob later told Stellar Magazine.
"If they're not ready to don that khaki and go feed crocs? Mate, it's not happening!" he added.
