Six unlucky in love Aussies have been matched and will now be married and stranded together for 21 days to see if in the wildest ever dating experience they can find everlasting love.

Three new couples say "I do" and are whisked away to Honeymoon Island with nothing more than the clothes on their back.

It's the first Couples Cove for the newlyweds and sparks are set to fly.

Day six hits on our Honeymoon Islands and our couples deep dive into an intimacy crate after washing up on their shores.

It's day eight and the couples receive another surprise crate and face off at the next Couples Cove.

While some relationships thrive, others face challenges, with the aftermath of Couple Cove's still lingering in the air.

As one couple pulls the flare and leaves the experience for good, two couples ignite fire in another way by taking their relationship to the next level.

A peek into life beyond the island's shores will burst their love bubbles and the newlyweds will be left to contemplate if they can truly see a future with their partner.
