The Bachelor Australia's Rachael Arahill and Vakoo Kauapirura are reportedly in a relationship.

Rachael and Vakoo weren't a match for The Bachelor's Matt Agnew, but they have reportedly found love with each other.

The women were seen kissing at a Sydney restaurant in photos published by New Idea on Monday.

"They formed a really strong friendship in the mansion and their feelings for each other quickly developed into something more," a source told the magazine. "They ended up hooking up in the mansion one night after one of the first cocktail parties. It was never filmed, and producers never found out."

And now the women have seemingly continued their romance off-screen.

"The girls would always see them together, going for walks alone, and started to question if they were more than friends but they never confirmed it," the source added.

It's claimed that the women are "still together" but have tried to keep their relationship a secret.

"Rachael told producers one night in her piece-to-camera that if things didn't work out with Matt she had 'plan B' — and everyone thought she was referring to a crew member or someone back home, and it became this big scandal in the house, but she was actually talking about Vakoo," the source said.

"Rachael and Vakoo are still together but have been keeping things on the down-low since they got out."

Rachael posted pictures with Vakoo while she was in the mansion, and said that they had formed a strong bond during filming.

"Thankful we went on this crazy journey or I wouldn't of met my soul mate OmG bLeSsEd WiTh ThE bEsT xX," Rachael wrote on her Instagram.

In this week's episode, it's expected that Rachael will have a fiery confrontation with Matt after he's told that she's been flirting with a male crew member.

Matt interrupts one of Rachael's confessionals and appears to call her out for her inappropriate behaviour on set.

"I'm going to confront her and see if we can sort this out," Matt says in the promo.
