"I missed you❤ Wonderful to be back @AustraliaZoo after celebrating New Years in gorgeous Tasmania together," she wrote alongside a cute pic of herself cuddled up to Powell. "Ready for lots of fun these Australian School Holidays doing shows at #AustraliaZoo."
Irwin, 18, and Powell, 20, first met in November 2013 while he was visiting the Australia Zoo, and have been dating long-distance ever since.
ET sat down with the young couple for their first joint interview in October, where Irwin adorably revealed that the moment she knew Powell was the one was the first time she saw him in Australia Zoo khakis.
"It's this really big thing for me," she explained. "It was kind of one of those moments that was a real defining moment for me, because you know, it's only the people who are the closest to us that get their khakis."
