The Love Island Australia star, 26, stripped down to a tiny green swimsuit that barely covered her assets.
She posted several snaps as she posed wearing a matching sarong beneath beachy cliff rock.
It comes after the model recently confirmed she has a new man in her life, months after her split from boyfriend-of-four-years Josh Moss.
While she didn't reveal his name or face, the black-and-white photo suggested the pair were dating as both their legs were intertwined.
The picture may have been taken during Amelia's recent trip to Mykonos, where she shared countless sizzling snaps but didn't reveal a mystery beau.
Amelia Marni visited Greece, Paris, Ibiza, and London while getting over her recent break-up over the scorching European summer.
She appears to be adjusting well to life after calling it quits with Josh, 29, whom she dated for about four years.
Following their break-up, Amelia announced she would be relocating from Australia to Europe for several months.
She hinted a 'casual move' was on the cards but returned to Australia in mid-August.
