But one contestant is also setting pulses racing off-screen, thanks to a series of racy videos discovered by New Idea.
Martha Kalifatidis, a makeup artist from Melbourne, caught the attention of viewers with her surgically enhanced figure and Kardashian-esque looks before footage emerged of her shaking her peachy derriere for a male companion last March.
And in another clip obtained exclusively by New Idea, the Greek-Australian stunner is seen flashing her underwear for the camera during a raucous night out at the Albion rooftop in South Melbourne.
The video was recorded inside the bathroom of the Albion in May 2018, where Martha was partying with a group of male and female pals.
Dressed to kill in a strappy black halter top and leather skirt, the 30-year-old beauty pro pulls open the zip to reveal a tiny black lace thong.
Her raven locks are styled in loose beachy waves and a dose of heavy black eye makeup makes her a dead ringer for her self-professed idol Kim Kardashian.
A gentleman friend drapes himself round the up-and-coming reality star while she sings lyrics from the provocative hit Last Night by American R&B group Az Yet.
Martha took the plunge and applied for the social experiment after six years of being single, which she openly attributes to her high standards, pickiness and obsession with control.
The Bondi-based cosmetic guru has been candid about her fear of being hurt by men, shutting herself off from potential relationships as a result.
After being matched with 27-year-old Michael Brunelli, Martha was immediately smitten and the pair jetted off for a romantic honeymoon to Samoa.
