Married at First Sight is an Australian reality television adaptation of the Danish series Gift ved første blik. The show features a group of strangers who participate in a social experiment and are paired together by experts. Due to the legal requirement to give one month's notice of marriage in Australia, participants in this installment are not legally married, instead proceeding with an unofficial commitment ceremony. The series first premiered on 18 May 2015 on the Nine Network. The show has had twelve seasons between 2015 and 2025, plus a two-part reunion special which was broadcast before the eighth season in 2021.
