The experts return to pair 22 Aussie singles in the controversial social experiment. The first two couples walk down the aisle, but one bride's brother causes a bump on her road to love.

Eight Aussie singles are set to tie the knot. There's just one catch: they'll meet for the very first time on their wedding day.

The couples begin the next stage of the experiment, as they pack up all their things and move in together, but a shocking twist shakes everything up.

To reach a happily ever after, one nervous bride must face her fierce mother-in-law's test before the wedding.

The experts match two more couples, pairing up plumber Mathew with student Alycia, and single mum Jo with pub manager Sean.

Emotions run high heading into the next commitment ceremony. There are big leaps as some are falling for each other, others are moving in, and two couples split.
