New Bombshell Mitch kisses Phoebe during a sexy strip tease as things heat up in the Heart Strips a Beat Challenge

The Love Island Australia 2022 Islanders sent pulses racing during Episode 19, as they competed in the raunchy strip tease challenge Heart Strips a Beat.

The task was simple. Each male and female would perform their sauciest dance moves in front of other Islanders of the opposite sex, who were fitted with heart rate monitors.

Then at the end of the challenge, the Islanders would discover which person raised their heart rate the most – and of course, some were less than impressed with the results.

You can watch some of the sultry performances in the videos above and below.

The most outrageous moment of the night came in the form of new Bomb Mitch, who poured oil on himself while showing off his glistening muscles in all their glory.

After rubbing up against the ladies, he grabbed Stella for a kiss before lifting Phoebe in the air for an incredibly steamy snog – while her current partner, Mitchell, watched on from afar.

"It was... smoking!" Phoebe said in the Beach Hut.

"That is my Kryptonite. Pick me up, kiss me and I'm yours."

Yikes, poor Mitchell!

"Mitch kissing Phoebe wasn't very nice," Mitchell admitted. "I kind of closed one eye and pretended it wasn't happening. It wasn't good."

When it came to Mitchell's turn, he bizarrely chose to wear a Jason mask from the horror movie Friday the 13th.

"Not sexy vibes at all. Why are you wearing that? Be hot, be sexy!" Phoebe scathed in the Beach Hut.

Andre came in hot as a sexy soldier, and dropped Claudia to the floor before doing a raunchy dance on top of her.

Meanwhile, Al rocked up as a police officer, Tak showed off his best moves as a sexy football player – even whipping out the worm to impress the ladies – Callum danced in a glittery ensemble and Jordan arrived as some sort of lion.

For the ladies, Jessica was up first and performed in a sultry police officer costumer.

"Someone's been a bad, bad boy," she said as she hit the ground with her whip and grinded on the lads, while Al said in the Beach Hut: "Wow. Whip me, baby!"

"I can't dance, so don't get excited!" Claudia said as she rocked up in a racy nurse outfit – but despite her words, Austen couldn't take his eyes off her.

"Claudia was next level sexy," he said. "I promise you, my heart started racing as soon as she came down!

"She was dancing on other guys, and I still could not keep my eyes off her. If that was my nurse, I would be sick every day."

Phoebe H came down in a saucy red devil costume, Maddy performed some saucy moves in a sultry butterfly costume, and Stella strutted her stuff a pink feather boa as she planted a kiss on Tak.

Phoebe, meanwhile, took things to the next level as she dragged her partner Mitchell onto the floor and shared a steamy kiss with him in front of the other Islanders.

After the challenge was over, the contestants were told which Islander raised their heart rate the most, and the results are below:

"There's cracks in the door so you've got to kick the door down!" New Bomb Mitch said in the Beach Hut, after realising he and Phoebe raised each other's heart rate the most.
