The thirteenth season of Married at First Sight premiered on 2 February 2026 on the Nine Network. Relationship advisors John Aiken and Mel Schilling, alongside sexologist Alessandra Rampolla, all returned to match nine brides and nine grooms. Halfway through the experiment, the experts matched another two brides and two grooms together, as well as two grooms in a same-sex couple.
Following on from issues in past series, with investigations by New South Wales Police Force and Safework NSW, the show will provide a domestic violence support hotline number and the tag line, "Aggressive behaviour is never acceptable". This was SchillingâÂÂs last season as a relationship advisor after revealing her cancer had been terminal; she died on 24 March 2026.
