An Irwin test isn’t the only obstacle the couple have had to navigate, though, as they are currently in a long-distance relationship. Robert lives in Queensland, while Buckley is located in Western Australia. However, it seems to be going well, with the news outlet reporting the young lovebirds are making it work.
It comes after the couple appeared on their first red carpet together ever.
Wearing matching all-black outfits, the 19-year-olds looked loved-up at the Sydney premiere of Mission: Impossible - Dead Reckoning Part One in July. Posing for the cameras, they even appeared to share a few private jokes together.
Robert was first spotted with Buckley last year as they sat cuddling on a beach in Queensland.
The conservationist was snapped with his arms around her last November as the couple shared some burgers and watched the sunset.
Buckley was later spotted sitting with Robert and his mum at the Australia Zoo crocodile show on his birthday last December.
