Erin Bateman and Bryce Mohr, season two
MAFS' longest-lasting couple met on the 2016 series and with the exception of a brief break up in 2017, they've been rock solid ever since.
As for the secret to their happy relationship, Erin says it's because they keep their personal lives out of the public eye.
"I'm sure it infuriates a lot of people that they're not kept in the loop because the nature of reality TV is you then go on to flaunt your whole life on social media," Erin explained to fellow MAFS star Bella Frizza on her podcast, The D&M.
"I don't think it's normal. I know personally people who portray their relationship on social media as this fairy tale, who are some of the most miserable people I've ever met, in terms of relationships."
Erin also revealed: "The Bryce I got the day that I met him is the Bryce I have today. He hasn't changed at all. He is exactly who he is, and I'd like to think he feels the same about me."
Cam Merchant and Jules Robinson, season six
When Cam first laid eyes on his match, the cricketer admitted that she wasn't his physical type.
"I was way too short and Jules was red-haired, curvaceous, tall and I thought 'This is a stitch up here!' But once we met and sort of locked eyes, there was this comfortable warmness that came over and all the judgement went out the window," he explained on The Babble podcast in September.
He added: "We were able to put all that s*** aside and see what's actually on the inside and we fell in love that way."
And it certainly worked! The couple were the MAFS 2019 golden couple and at their final vows Cam popped the question to Jules for real.
The pair tied the knot in November 2019 and welcomed their son Oliver Chase in October.
Martha Kalifatidis and Michael Brunelli, season six
2019 is MAFS' most successful year to date! Cam and Jules may have received most of the attention but Martha and Michael were the quiet achievers.
The attraction was instant and fast forward to now, the couple are living together in Sydney, their fans waiting with baited breath for an engagement or baby announcement.
"Our foundations are similar and we have strong family values."
