It's the powerhouse franchise that's responsible for some of the nation's greatest love stories, including the Bachelor's first-ever husband and wife, Tim Robards and Anna Heinrich.
But behind all the roses, champagne and helicopter rides, there have been some truly jaw-dropping moments to have plagued the reality show.
As we countdown to the Honey Badger's big debut, which is just weeks away, we take a trip down memory lane and round up the biggest Bachelor shocks and scandals of all time.
When season two's Blake Garvey proposed to Sam Frost...and then dumped her for Louise Pillidge
In 2014, we all cried-happy tears when real estate agent Blake Garvey went down on one knee and proposed to Australian sweetheart Sam Frost.
But in a twist no one saw coming, it was revealed love rat Blake had broken Sam's heart and turned his attention to Louise Pillidge, who was the third runner-up.
While Blake and Louise dated for 18 months, the two eventually split and said that their relationship's controversial start was to blame.
Since then, Blake's gone back to his old life in Perth and Louise is living her best life as a producer on the Gold Coast.
As for Sam? Between her stint on The Bachelorette, her breakfast radio hosting gig and her acting role as Jasmine Delaney on Home and Away, she's since found love with Dave Bashford.
When Blake Garvey's stripping past was exposed
As if his reputation wasn't tarnished enough from his romantic choices, his past career came back to haunt him too.
Not only was Blake a stripper in his younger years, but he was also the owner of Alpha Male Entertainment, dubbed as "Perth's premier male entertainment provider... for everything from hens parties to ladies nights and birthday parties".
Speaking to The Herald Sun about how he started stripping, Blake said, "A high school friend had someone pull out at the last minute for her hens' night and needed a fill in. She begged me."
"I gave it a whirl, it was pretty funny. We've all had adventurous pasts."
Some more adventurous than others, it seems.
When season one's Tim Robards was outed as a topless dancer
Tim Robards may have had a squeaky clean image during season one when he found love with Anna Heinrich, but he was certainly a wild thing in his twenties!
"We did a few hen's nights and it was just all about making the girl feel special and serving them champagne and whatnot," Tim, who recently married Anna in a lavish Italian ceremony, once revealed of his former job.
When season four's Megan Marx and Tiffany Scanlon dated each other
They met while trying to win Richie Strahan's heart in 2016 but turns out love was staring Megan Marx and Tiffany Scanlon right in the face.
Writing for Mamamia, Megan says that the early stages of their relationship and facing the public as a same-sex couple was difficult, especially for Tiffany who had never dated a woman before.
"Being a self-proclaimed D-grade celebrity and having to watch someone I care about undergo so much online and face-to-face bullying makes me wonder how the likes of Amber Heard, Ruby Rose and the many other women who bravely 'came out' at some point – who are a thousand times more under the public spotlight – deal with the pressure."
The two blonde bombshells made the conscious decision to inspire and help normalise same-sex relationships but called it quits in February 2017 when the pressures of fame became all too much.
On her blog The Tiffany Times, Tiffany wrote, "We made the decision (mistake) at that point to share our relationship with the public," Tiffany penned "This, I believe, would eventually cost us our relationship."
While Tiffany is still travel and health blogging, Megan has now moved on with her Bachelor in Paradise boyfriend Jake Ellis.
When Brett Moore turned up to Bachelor in Paradise in a relationship
One of the main requirements for appearing on a reality dating show is that you're single.
Turns out Brett Moore, who first appeared on our screens during Sophie Monk's season of The Bachelorette in 2017, turned up to Bachelor in Paradise while he was already in a relationship with another previous Bachie contestant, Stephanie Boulton.
Apparently, the plan was to keep Brett on the island so he could be reunited with Stephanie later on in the show when she arrived as an intruder. To make matters more complicated, Brett's friend and Bachelor in Paradise co-star, Tara Pavlovic, was caught in the middle of it all and accused of helping him.
In the end, a producer had to explicitly ask Brett if he's single which is when he admitted he was "seeing" Steph but they weren't "Facebook official."
Well, at least they're happy together now.
When Bachelor in Paradise's Leah Costa faked her engagement
Back in 2017 when she was competing for Matty J's heart, Leah was outed as a topless waitress by her fellow contestants and asked to leave in one of the most hypocritical moments in Aussie TV history.
But it was her engagement hoax that caught everyone's attention this year, following her appearance on Bachelor in Paradise.
Rumours circulated that Leah was engaged after she was spotted with some very noticeable bling on that finger. While Leah neither confirmed or denied the news, she admitted she was in a happy relationship shortly after the show wrapped.
But in a now deleted Instagram post, she confessed that the whole thing was a publicity stunt to prove how the media sensationalises everything.
"In an era of fake news and 'unreal' TV we are all constantly left questioning what to believe. Editing and manipulation are often highlighted when we are discussing [sic] the media. But what about the power of suggestion? This is the most important, because without actually saying anything, you can position individuals to create and accept their own version of the truth. We have seen this done in countless political campaigns, wars, media and now reality TV."
When it was revealed that Keira Maguire grew up in a cult
In a Woman's Day exclusive, sass queen Keira Maguire's heartbreaking upbringing was exposed when we learned she grew up in a polygamist cult with 63 siblings started by her father, Alistah Laishkochav.
With no contact with the outside world, Keira and the other children from various mothers – some of whom were also sisters – stayed with their families and were often told outsiders were "evil" and that God would save only them.
In a statement to Woman's Day Keira explained, "I am not in a position to comment on Alistah Laishkochav. My mother removed my family from that environment when I was five years old, over 25 years ago. I was brought up by my mother and grandmother in Brisbane in a loving, caring and compassionate household."
"I had a wonderful childhood and I am extremely grateful to both my mother and grandmother for the upbringing which they provided me and my siblings. Although I have since met and reunited with my family, I have never had a relationship with Alistah Laishkochav. Alistah Laishkochav is not relevant to who I am nor does he define me."
When Sam Wood hooked up with contestant Bec Chin a year before he was The Bachelor
It's always a bit awkward when you run into an ex, but what if you do so on national television?
In season three of the show, that happened to personal trainer Sam Wood when he "met" dietitian Bec Chin at the first cocktail party.
OK they weren't exactly exes, but Sam and Bec met a year before the show aired at a cliff-top restaurant in Bali.
Bec's friend told Woman's Day that the two had sizzling chemistry and ended the night in each other's arms, kissing and cuddling.
That's all in the past though as Sam and Bachelor winner Snezana have settled down with Snez's daughter Eve and their bubba Willow Wendy Wood. Bec also found her happily ever after and gave birth to daughter Savannah Rose in December 2017.
