Aussie families are trapped in a clutter nightmare they're desperate to escape. Declutter guru Peter Walsh, renovation queen Cherie Barber and treasure hunter Angie Kent transform people's homes and lives.

After years of relentless school bullying, Ben's drag persona Carla from Bankstown became his saving grace. But as their star rose, so did the clutter! The team must get to the crux of Ben's past to reclaim his family home.

Between managing six kids and house full of clutter, Karisha and Simon have lost control of their relationship and the mess that surrounds them. Together, they must find middle ground and rework their priorities to help reunite the family.

Sandra is drowning in the clutter left behind by her late husband. And with daughter Denise her only support, the situation has become overwhelming. Can the team help heal old wounds and give Sandra the new start she deserves?

After the arrival of their miracle baby, Kylie and Paul's lives spiralled out of control. With a home literally buried in clutter, Peter and the team must sort 512 boxes and renovate 7 rooms in their biggest challenge ever.

Fulltime nurse and single mum Kathy dedicates her life to caring for others, but it comes at a great cost in her home. With the help of her two daughters, she must conquer her deepest fears, while Cherie has just 3 days to renovate 6 rooms.

Blending two families under one roof is proving a major challenge for Tracey and Stuart. They're swamped with unwanted clutter and painful memories from the past. Peter and the team create a roadmap for a fresh start.

In a very special Space Invaders, we revisit some past favourites to see life after the cameras stopped rolling. Steve and Maria face a new health crisis, Luke and David leave Peter in shock, while Jamie battles a new challenge.

Single mum Ingrid and sister Garman moved in together following the death of both their parents. But Garman's extreme collecting has left their home buried in clutter, creating an unsafe place for Ingrid to raise her daughter. Peter has his work cut out attempting to break the cycle, Cherie arranges a special treat for the family dog, while Angie sets about repurposing a treasured piece of furniture.

Clutter has taken over after Christine and Daniel's dream to knock down and rebuild their home collapsed. As conflict threatens to tear the family apart, Peter must bring love and joy back into their lives.
