An initial glimpse of the trailer was teased on the Married at First sight Instagram on Sunday and then officially aired during The Block Grand Finale, showing the first batch of the 20 couples who will star on the show hoping to meet the love of their life.
Out of 20 contestants we only got a sneak peek at a few lucky suitors.
The first being Gabrielle, who explains to the audience she wants someone to share her life with.
'I really, really thought I would have a partner and have kids and a family. It's hard that I'm not there yet.'
The next was Matt who explained, 'I'm definitely lonely. I want to find someone to grow old with. I absolutely believe in love at first sight.'
We were also lucky enough to meet a few others in the short promo.
After four seasons and 48 contestants, only one couple who met on Married At First Sight have stayed together, Alex Garner and Zoe Hendrix, and they just recently welcomed their first born child - Harper Rose.
The new season officially airs in 2018.
