Meanwhile, another fan has also noted that Irena and her BFF Bella Varelis, no longer follow each other on Instagram, which is surprising seeing as they are so close on-screen.
"Notice how Irena and Bella don't follow each other on Instagram... definitely means one of them wins so it is awkward now," one user noted.
And while betting websites have all tipped Irena to take out the top spot, even current contestant Areeba has her eye on the Melbourne-based nurse to win, saying that there's no way Bella is the winner as that outcome would be "too obvious.
"Where is the suspense? In all honesty, if I was making the show and Bella won, I would be like, 'oh okay,'" she revealed in an interview with Perth Now.
"I think Irena [will win]. I think Bella is too obvious, there is way too much connection already. Irena is a sweet girl."
