While Locky and Irena are yet to confirm the news, the 31-year-old nurse followed up with a picture of them kissing on the romantic getaway.
“One very lucky girl 🥰 @locklangilbert #rottnestisland ☀️”, she captioned.
It's also not the first time the couple have sent fans wild with engagement rumours.
While quarantining in a Perth hotel, Irena uploaded a photo of herself wearing a purple ring on that finger, which fans quickly noticed was the one gifted to her on The Bachelor finale.
Melbourne-based Irena made the decision to move to Locky's hometown just a few weeks ago.
"If Irena doesn’t like it and misses Melbourne I’ll be happy to head to Melbourne after COVID’s gone and try it there. But she’s going to fall in love with Perth, everyone that moves there ends up staying," Locky said ahead of the move.
Irena added, "I’ve got a few friends over there already so that makes it easier and I’ve found work. I think it will be a real easy and smooth transition."
