In the final Biggest Loser Singles Thursday night special for the season, we saw Graham maintaining his exercise routine using techniques that Commando would be proud of. He also especially ordered in some truck tyres to help him with his training. Some extra behind the scenes footage showed Alex giving it all back to Commando that left him feeling unusually out of control. Sammy sneaks into Camp Biggest Loser to have a chat with the remaining contestants and Trainers. Kasey shows Sammy her secret doll collection that represents her family members. Margie’s bedside shrine to Michelle is exposed as Margie confesses is her secret training weapon. Dr Norman Swan caught up with Graham and revealed his Bio Age has dropped from 54 to 43. The Trainers go head-to-head as Shannan and Commando do a number of tests that determined who is top dog. Commando’s Bio Age proves to be one year younger than Shannan.
The Trainers arranged some special Trainers for the remaining contestants. John Eales teamed up with Margie, Nat Cook with Kasey, Bob from Series Four with Alex and Eamon Sullivan teamed up with Brenda. It was a case of déjà vu for the remaining contestants as they hit the slippery slopes of Valley Stampede Challenge once again. This time, they were tied together to their respective trainer. The light hearted competition had the contestants go through hell as they crawled, climbed and swam through a muddy obstacle course. Team Margie crossed the finish line first, followed by Brenda and Shannan, and then came Kasey and Tiffiny, followed by Alex and Commando. As the contestants crossed the finish line, they were met with some familiar faces as the contestants looked to their past to see what they no longer wanted for their future. Each contestant was given a DVD of their audition tape and asked to watch it and vow never to fall into those people again.
Alex went Commando style on the poor helpless clients at Train Australia and made Commando proud. Alex’s new Bio Age was revealed having reduced from 71 to 54 years. Margie got into some secret training with Michelle and tried to throw the others off her scent. The contestants were then surprised with the MasterChef himself, Michael Moore from Summit Restaurant as he showed the Singles some impressive, low calorie party dishes that each contestant needed to prepare. The contestants are surprised with a cocktail party at the coolest club in town – Camp Biggest Loser. With each contestant getting dolled up and meeting some possible suitors.
An Elimination aftermath has the contestants explaining to their Trainers that unfortunately Bek was eliminated. Michelle surprises Margie with her secret weapon – a cardboard cut out of Michelle’s face attached to the fridge. The contestants are locked out of their Gym and are surprised with a video explaining that it’s time to Train the Trainers. Watching from The Bunker, the trainers realise that they are in for a world of pain as the contestants let loose on them. The contestants get their revenge on their Trainers and really let them have it. The Trainers then went head-to-head in a Sumo wrestling match that had everyone laughing. Kasey and Margie are the first to unleash their new found training confidence at the Train Australia event, much to their Trainer’s surprise.
After an epic week facing their fears on the Swiss Alps, the contestants returned back to Australia to a special homecoming surprise. Family and loved ones were invited to Camp Biggest Loser. Loved ones got the chance for contestants to show them how far they’ve come as they experience what it’s like to go through last chance training. The contestants then say goodbye to their family and friends as they prepare for the Weigh In and Elimination. Kasey and Bek unfortunately fall below the yellow line and it was up to the remaining three contestants to vote. After a hung vote, Margie decided that it was time for Bek to leave Camp Biggest Loser.
The contestants take part in a little shock therapy as they take an invigorating Arctic plunge to represent the start of a refreshing new start. They even get some playful payback, as they get into a snowball fight with the Trainers. Haley is back and introduced the remaining six to their next Super Challenge. The contestants had to trudge their way through fresh snow for 1km, jump on a traditional Swiss sledge and navigate 500m down a Swiss snow track, cycle over 9km, reach Interlaken’s rail bridge and repel 20m down to the river below, then kayak 500m down the river and do a final sprint into the centre of Interlaken to face a table of traditional Swiss dishes. The person holding the highest calorie dish was to be eliminated. The contestants battled resulting in lots of thrills and spills as they raced to the finish line. Margie arrived first, choosing the raspberries plate, Bek then decided on the Swiss hot Chocolate, Kasey came by next choosing the Bratwurst sausage, Brenda arrived shortly and hastily decided on a cheese plate, Graham stuck to the Swiss Chocolate and Alex forcefully takes the Potato Rosti. The Swiss Chocolate was the hard hitter, sending Graham home and out of the competition. With the finish line in sight, it’s time for the contestants to head home.
With ‘Dreams Week’ coming to an end, the contestants lived their dreams and faced some of their demons. The trainers went hard with some last chance training before Elimination. In training, Graham took back control as he gave it his absolute all, much to Commando's surprise. Margie felt a little lost without Lydia, so trainer Michelle focused in and managed to harness Margie's inner strength. At Weigh-In, Kasey’s immunity kept her safe, while Graham and Lydia were left below the yellow line. The contestants faced a difficult vote, but Graham was four times lucky in the Elimination chair, which ultimately sent Lydia home once again.
