And in a series first, two men will also be getting "married" onscreen....at least they were.
The Daily Mail has reported that Adelaide-based hospitality worked Simon Flocco withdrew from the show, despite already having filmed his backstory and meeting costars at the bucks night.
"He kept having doubts, expressing his discomfort," an insider source revealed to the publication.
"He kept telling them that he didn't feel comfortable about certain things but was eventually talked into staying."
"Producers, hungry for a groundbreaking narrative, persuaded him to stick around. That's why he was at the bucks."
Simon himself then went on the record to say that he withdrew from the show as it "wasn't what [he] thought [he] wanted at this point in [his] life."
"I just felt bad for whoever they set me up with. I did initially leave, but they managed to coax me back...I gotta look out for myself."
The almost groom then fled Australia for Europe, where he has been holidaying since July. All scenes featuring Simon and his "groom" Michael will presumably be edited out of the show.
Speaking to Yahoo Lifestyle, an "insider source" revealed that producers were looking for a more diverse cast of people from all walks of life.
"Producers want a more diverse cast that will cover a wider range of social issues, sexualities, and genders than previous seasons," they said.
"The show is meant to represent modern-day Australia, and producers are making a real effort to do that this time round rather than just having another cast full of cis-gendered, heterosexual participants."
The supposed insider then hinted as an individual being cast who "identifies as non-binary, gender-fluid or is trans."
At the 63rd TV Week Logie Awards, expert John Aiken said "Diversity is going to be the word that I would use for this cast."

Speaking of the cast, Channel Nine's Content Production and Development Head Adrian Swift has revealed to the Herald Sun that the new season would see a major adjustment in "tone."
"We have tried to move away from the screechy and the shouty," he said.
"We still give it all the drama that it needs, but we've tried to absolutely make sure all the relationships we see genuine potential in."
"This year what we have tried to do really carefully, exhaustively, is go 'is this right?'"
"There will still be those moments when they (contestants) take one look (at each other) and it all goes south, but we are hoping that there is a lot of love in this season."
