The dance partners and friends were featured in 17-year-old Irwin's Instagram page Monday, smiling next to a large rhino as it munched on grass close by.
"So happy to get to introduce you to our world here in Australia!" the daughter of late Steve Irwin wrote of Hough. "You are officially a Wildlife Warrior. Bring on the adventure!"
Using the same photo, Hough announced he was "reunited with my little @bindisueirwin," on Instagram. "A.K.A. The Champ!!!" he added.
In Late November, the wildlife conservationist and her professional dance partner were crowned the Season 21 winners of Dancing With The Stars in Los Angeles.
The duo performed a heartfelt dedication routine in honor of the late Steve Irwin during the competition's finale to Leona Lewis' "Footprints In The Sand." The dance earned a perfect score from all three judges and brought not only Irwin, but many around her to tears.
"For me, this whole experience has meant the world, for my whole family," she said at the time. "And it's changed my life."
