After 101 days of renovating for four couples it all comes down to this. For Jason & Kirsten, Jamie & Andrew, Jane & Matt, and Richard & Steven tonight's the night we find out who will take home the grand prize of $100,000.

After 101 days of renovation it's time to say goodbye. Some leave as friends, some leave as enemies.

The stress of living on The Block is taking its toll on the couples, and the big day is here for Matt and Jane as they return to Melbourne to get married.

Dani and Monique face their worst nightmare when a newspaper article discloses information about Dani's past. He and Monique are prepared to leave The Block if the other couples want them to go. Lies and back-stabbing are rife as speculation mounts about whether one of the other couples is playing by the rules.

The living conditions are getting down and dirty and the couples are racing to do those last minute jobs. They'll do anything to impress the judges as they try to win the biggest prize yet.

Nothing is going to plan. The couples are out of time, they're out of money and they're all going out of their minds to deliver room number four.
