Instead of a legally binding marriage, the couples will have a commitment ceremony.
After this, they will head off on a luxury honeymoon before returning to the UK to live alongside the other couples.
They will all be based in the same building and the couples will reunite weekly at commitment ceremonies.
As well as this, there will also be weekly dinner parties so viewers can expect plenty of drama.
Married At First Sight Australia airs on E4 on weekdays.
