Married At First Sight is an Australian reality television adaptation of the Danish series of the same name. The show features a group of strangers who participate in a social experiment and are paired together by experts. Legal restrictions in Australia mean that the couples do not partake in a legally-binding marriage as prohibited by the Marriage Act 1961. Rather, contestants engage in an unofficial commitment ceremony. The series first premiered on the 18 May 2015 on the Nine Network. The show has had nine seasons between 2015 and 2022, plus a two-part reunion special which was broadcast before the 2021 season.
