Big Brother — Season 1

Twelve housemates enter the Big Brother house, facing an immediate challenge: their belongings are locked away! Big Brother introduces a twist, forcing them to compete for their luggage. A thirteenth housemate, chosen by Australia, awaits.

The first shopping task is on and housemates have to rank each other from Most to Least and egos get checked. Results are revealed for the 13th housemate to enter the Big Brother house.

Housemates learn the results of the shopping task and choose one to go shopping for the week. Later, housemates are given 90-seconds to find their newest housemate hiding somewhere within the Big Brother house. Housemates are still missing some of their wardrobe and personal items.

Tonight, housemates have a group dinner until conversations get personal and someone gets upset. Later, housemates nominate live, each person is given 5-points and must nominate two other housemates each and use their five points to assign 1-4 points to each person they nominate. The points are tallied at the end of the nominations, the housemates will the most points will be up for eviction by the public vote.

Today, a blooming showmance is causing tension and conversations. Big Brother's Bargain Basement has been forced into liquidation and housemates must buy back their personal items from BB's Bargain Bin, but not with cash...with plea bargains, literally begging for their stuff back.. If successful, their items will be falling and flying out of the bins. Finally, we get to see the fallout after yesterdays live nominations and one nominee can't figure out where their votes came from or why. 

Housemates wake up to another day in the Big Brother house, a few, ruffled about the new showmance. A house meeting is called under the direction of giant piece of macaroni about the house food situation until the topic changes to that awkward showmance. Tension and tears developed that left one feeling isolated. Meanwhile, two housemates were given a secret mission to sneak party supplies from one end of the house to the other without anyone seeing in order to earn a surprise party.

It's live eviction night!! Tonight, the first housemate will be evicted from the Big Brother house. But first, Colin asks Holly if she considers herself a flirt after practicing a dance routine with Bruce for fun and now she is questioning her actions. And, stomachs growl in the kitchen over how much food some people are getting...taking. 

Evicted housemate, Michael drops a grenade in the Big Brother house by leaving some very opinionated observations and decides who the first, "Head of House," for the week is who must delegate household chores to various housemates. Feathers will be ruffled! Michael returns and explains his decision to Mel. And finally, the Head of House is granted a game-changing power.

The Head of House, Holly, cracks the whip making sure everyone is doing their jobs which some people see as being bossy. This weeks shopping task takes place to operate Big Brother's food delivery service, BB EATZ. And, the aftermath of nominations is unleashed, Jane "as a woman," feels disrespected, and a bad smell is in the air...oh wait, that was Colin.

The BB EATZ shopping task continues when the kitchen reopens at 4am. Round two of Jane vs the Boys hits off. Housemates learn the results of the shopping task and Holly goes shopping for their weekly groceries. At dinner, housemates reveal their first love and someone gets to speak to a loved one on the outside.

Big Brother left the BB EATZ order phone in the house and it has been ringing all day with rewards, challenges and decisions decided on by the public. Mia has a crush on Ed which turns into an awkward conversation after an overheard imaginary phone call. Housemates play two truths and a lie and later, the coffee bandit returns.

Another day in the Big Brother house starts with Colin being blown away by a laundry cleaning hack involving an ice cube. Coco shares her first impression of Holly...it was not received well. Big Brother opens the Q&A phone lines and a one sided bet has Mia running the distance for Ed. Big Brother plans a high-end VIP party and Holly gets to pick the guest list and the chosen working staff are not pleased.

It's DOUBLE eviction night!! An early morning phone call gives one housemate a choice to take $10,000 cash OR add $25k to the final prize fund. A house meeting was called by Coco who wants housemates to respect each other after hearing a comment Holly made about Emily which causes some intense conversations. And Colin is counting and sitting in a vent.

Tonight in the Big Brother house it is live nominations, but first, Jane is back with her final thoughts on everyone and select the next "Head of House." Mia also pops by to provide her final opinions on all the housemates and she is granted the ability to cast her nominations and points for the week.

The day starts with chosen housemates performing their daily chores. Later, all housemates pack up their suitcases as Big Brother opens, The Grand BB Hotel as part of this weeks shopping task. Housemates are either staff, or guests and Big Brother has a secret...devious and diabolical task for the guests during their stay.

It's another day at The Grand BB Hotel, where service never sleeps and the staff begin to crack under the relentless pressure and demands from the guests. Will the staff be penalized for breaking the rules or will the guests be the ones who lose the shopping task because they don't want to push the staff over the edge?

It's the third day at The Grand BB Hotel and time for check out. Big Brother reveals the results of the shopping task and lets the staff in on what the actual task of the guests were, and, they were not too happy. Two showmances in the house have some serious conversations about the future of their relationships.

It's a beautiful day in the Big Brother house, even the flies are high on life. Emily, while trying to rescue flies is given a secret, blockbuster mission with a big plot. Bruce apologizes and Coco keeps reminding him of what he did wrong. A new theme is activated in the house, The Wild, Wild West.

It's live eviction night in the Big Brother house...who will go...Bruce? Conor? Holly? Or Vinnie? But first, Christmas arrives the Big Brother house complete with snow, presents under the tree and stockings. Big Brother offers $15,000 from the prize fund to any housemate that rings the Christmas bell, but it comes with a game changing decision. Finally, Coco's Christmas Cafe opens for business for a secret mission.

The final week of Big Brother Australia begins and the fall out from Holly's eviction rings around the house with her "last words" to the house. All the housemates get to select a gift from under Big Brother's Christmas tree, and one person will be granted a nomination advantage of ten nomination points  and they will cast their vote live. And the "Head of House" decides whether to leave nominations the same or save one of them from eviction only to put someone else up.

Another Christmas day in the Big Brother house and more shenanigans. Coco must invite two guests to Coco's Christmas Cafe...can she serve them up without getting caught? And a new shopping task begins...housemates have 30-seconds every time Big Brother jingles his bells to get dressed in their Christmas outfits and sing a Christmas Carol. Housemates get to watch as Ed gives his two live nominations. Vinnie calls Ed out on his speech about him. And in the middle of the night, one last Christmas Carol sends another housemate out the door!

After a shock, backdoor-midnight eviction, Vinnie was the sixth housemate to leave the house and joins Mel Tracina to discuss if he is real, or fake. Big Brother reveals the results of this weeks musical shopping task and Colin goes grocery shopping...oh dear. Emily reads a letter from Vinnie to all the housemates giving them his final thoughts, and a couple people were not impressed with his opinion. Finally, the last round of nominations take place and four housemates face the public vote.

Housemates wake up after a sleepless night and get to face their "Festive Fears" in a mini-shopping task involving Big Brother's BADvent Calendar. It each housemate can complete a small task, Big Brother will put up money for a final shopping budget. 

Today in the Big Brother house, housemates are doing everything they can to entertain themselves and reflecting on house relationships. Big Brother gives Bruce and Colin a task to sneak various items (including a Christmas tree) from the house and into the diary room in order to win a KFC feast for the house. Housemates play a game with Big Brother involving "guessing which housemate the public is talking about."  And, before the day is over, Colin learns how to eat a prawn and come to terms that the prawn WAS someone's son or daughter...

It is the final two days in the Big Brother and housemates receive letters from home, and one housemate receives some surprising news. Big Brother then gives each housemate a choice, "Stack or Steal" $25,000 - will someone's choice disrupt the house? Finally, another live eviction takes place and someone else walk out the door!

It's the live final in the Big Brother house and everyone will be evicted before the night is over and one will walk away with $135,000 as the winner of Big Brother Australia 2025. Although, Mel has an offer for one of them, to give up their chance for cash and take a brand new Suzuki Jimny XL. Who wins? You decide!
