Their fellow Paradise co-stars were quick to share their delight in the comments.
"Is that @the_life_of_gil famous Geraldton heartbreaker?" Alisha Aitken-Radburn joked in the comments, referring to newcomer Chris Gilleland to which he replied: "Breaker of few... mender of many!!"
Jessica Brody also suggested that Ciarran Stott soon departs the show, commenting: "Mine ran away so this is great news."
Last season's Florence Moerenhout added: "Oh wowwww plot twist."
However, fans of the show weren't too impressed by the Bachelor newbies, remarking that it goes against the whole premise of the show, which sees returning stars of the franchise aim for a second shot at love.
"This is ridiculous! It’s bad enough when they bring the American ones on!" one commented.
"Doesn't this defeat the whole idea of the show?" asked another.
"Do the producers not understand the point of Bachelor in Paradise?" a third noted.
"Don’t remember a single one of these blokes," another simply stated.
“They were unsuccessful for Angie [Kent]’s season but then got fast-tracked to Paradise. It was so bizarre,” one contestant explained to the publication.
“We had no idea who they were when they walked in. They thought that bringing in three random guys would rattle our cages; they wanted us to feel threatened,” another male contestant added.
It is believed that one of the intruders Conor, who is based in Tasmania, actually finds love with a Bachie favourite this season.
Thanks to some sneaky Instagram clues, fans have noticed that Mary Viturino has made several mystery trips to Conor's home state since filming wrapped in December.
Could these two be one of the happy couples at the end of the show?
