Season 4

Big Brother is back but with one massive secret. What is it? Gretel Killeen introduces this year's housemates, and reveals what Big Brother's hiding from them.

In a very special one-hour show, Big Brother turns the housemates' world upside down.

Ashalea gets a history lesson, Krystal reveals all, and has Terri found out about Big Brother's secret?

It's a day of high-spirited competition, although there's some unhappy campers as Elle cries for Krystal.

Merlin makes a confession, the house feels the wrath of the mighty Aphrodite, and there's a much-awaited homecoming.

A stressful day leads to break-ups and make-ups.

Before the housemates make their first nominations, they must expose their darkest secrets. Is anybody hiding who they truly are?

Merlin gives a warning to Igor, Paul's predictions get him in trouble, and a new love blooms.

The housemates make their first nominations - who will face eviction? They don't know it, but there's $1,000,000 riding on their choices.

There's something old, something new, something borrowed, and something blue.

Ryan lays down the law, Merlin's under siege, and blushing Bree is all aflutter.

It's the swinging 60s; The dirty dozen; and Ships ahoy in the shower.

A buck's night for the boys has the house alive in song, but the hens are ruffling feathers.

The housemates learn their fate, Ashalea finds age a barrier, and Aphrodite moves closer to her prize.

Igor, Aphrodite, Terri. Who goes? You decide.

Merlin has heartache, Paul has a headache, and Igor has a belly ache.

The housemates have barely recovered from the mighty Aphrodite's eviction, but they must enter the diary room and nominate once again.

Paul sums up, Elle breaks down, and Terri goes another round.

Igor's threat to leave prompts a Krystal-clear response. Meanwhile, strange weather has the housemates spooked.

We uncover whose chest is best; Which boys make the most noise?; and A little light music.

The housemates see the aftermath of the storm, Ryan gets the short end of the deal, and there's a Big Brother world premiere.

Lonely hearts, broken bones, and belly laughs.

Terri, Elle, Igor. Who goes? You decide.

Eviction fears have Elle in tears, Paul finds himself at the helm of a house split, and Ryan gives love advice.

Big Brother has given the housemates just five minutes to pack their bags for an extended stay. What's he planning?

Bree's patience spreads thin, nominations sound an unfamiliar ring, and barbed comments leave a sting.

It's a split in the house, but while some enjoy the riches, Elle's feeling fenced in. Meanwhile, Merlin has some neighbourly advice.

An epidemic in the house; Staying private in public; and Aye Carumba! It's time to samba!

Winners are grinners, but there are some sour grapes as Terri contemplates her future.

Terri's task trauma turns the tables, and Ryan's in all kinds of trouble.

Krystal, Paul, Ashalea, Terri. Who goes? You decide.

Terri survives another round, Catherine opens up about love, and it's all too much for Elle.

With all the girls seemingly in tears, where will this week's nominations fall?

There's strong words from Paul, stronger words from Terri, and tempting words from Bree.

It's raining melons, and Paul drops a bombshell that lands very close to home.

We go south of the border; Have a ripping time in Rio; and do the Cape Town shakedown.

Wonderful Wesley, wicked Paul, and weird Ryan.

Ryan wrestles with nature, Elle gargles with pride, and Ashalea bubbles with innocence.

The tables have turned on Trevor, dinner is on Merlin, and all eyes are on Elle.

Terri, Paul, Elle. Who goes? You decide.

There's only four girls left, and while the boys get deep and meaningful, the girls still can't get along.

The housemates must bare all as they make their nominations for the week.

Queen bee Bree, mighty Merlin, and crying Ryan.

The boys are feeling fabulous, but Big Brother rains on Wesley's parade, and Kane asks the million dollar question.

Hankering for a spankering; Three new tongue twisters; and Trevor teaches Ashalea the A-Z of the birds and the bees.

Ashalea tells it like it is, Ryan tells it like it was, and Merlin tells too much.

Big Brother's had enough, and it's Terri's party but Merlin will cry if he wants to.

Tonight is all about the famous, the infamous, the beautiful Mexican model with that little extra something meeting the housemates.

Anything can happen in Carnivale time, but there's no dancing around one topic, and the penny finally drops for Ashalea.

Merlin, Catherine, Bree, Terri, Paul. Who goes? You decide.

Wes makes an unlikely reveal, Miriam makes an unexpected offer, and there's an unbelievable eviction aftermath.

After last night's explosive eviction, Merlin joins Gretel to explain the actions behind his silent protest.

Romantic Ryan, moving Miriam, and anguished Ashalea.

More amore from Ryan, Catherine gets catty, and Ashalea gets agro.

Ash names names; Rootman comes to the rescue; and Hot bods and Greek gods.

Men in frocks, talk is cheap, and life-saving events.

Complaining Kane, secret speculation, and fragmenting friendships.

There's monster mud fight mayhem, Terri tears into Paul, but Ryan's heart is the only thing hurting.

Bree, Wesley, Ashalea, Terri. Who goes? You decide.

Paul forecasts bad weather, Bree predicts diary room distress, and there's a glimpse into Ryan's future.

Unaware of the massive week ahead of them, the housemates make their seventh nominations.

Gretel Killeen enters the Big Brother house to reveal Big Brother's big secret to just one housemate. Who will discover that the winner of Big Brother is walking away with $1,000,000?

The secret's out, and while those in the know are changing strategy, others are still in the dark as a load of cash gets between friends.

Our naughty nurse reveals all; Housemates in the halfway hub; and The empire strikes back: the return of Rootman.

Ash wants Ryan, but Ryan wants Bree, and Trev predicts it's all about to get very interesting.

The eight remaining housemates have been enjoying an isolated life, but tonight two intruders come to crash the party.

There's a new woman in Ryan's life and he's falling under her spell, but the magic is gone for Bree.

Bree, Ashalea, Kane, Wesley. Who goes? You decide.

Bree and Ash are treading water as the new intruders rock the boat, and Ryan's ship has just sailed into harbour.

The housemates now know the million dollar secret, and Big Brother drops another bombshell when he announces that the intruders cannot be nominated, but they can nominate. With the stakes so high, who will face eviction?

Ashalea's out of favour, Violetta's out of this world, and the house is out of toilet paper.

The housemates don't know it, but one of the new intruders must be evicted. Monica or Violetta. Who goes? The housemates decide.

Monica's moving in, but is she amongst friends? The old housemates adjust to the new.

The gleesome threesome; Rootman finds the Beast Bot; and Monica canes Kane.

True feelings bring Paul to the rescue and put Ryan on the rampage.

Lights, camera, action.

Ryan's in the mood for love, Monica's in the mood for games, but just how long have they got?

After facing Big Brother's wrath, all housemates except Monica face eviction. Who goes? You decide.

There's a new bird in town, but the mother duck has left the building, and one chick is ready to fly the coop.

All housemates face eviction this week, with two of them leaving in a double eviction, but this isn't the most shocking news the house will receive. Due to a voting tally error, Bree was wrongly evicted last night, and will be re-entering the house tonight.

It's the Bree-unification, but has it put her ahead or have her housemates left her behind?

The scoop on Monica, a reveal from Wes, and a candid conversation with Catherine.

What women want; What men want; and Hot bods ahoy.

Truly, madly, deeply.

Following Bree's wrongful eviction on Sunday, the time has come for the true evictee to be revealed and for them to leave the house.

The truth, the whole truth, and nothing but the truth.

Old friends have new faces while new friends have two faces. Meanwhile, the cameras roll on the shopping task.

All housemates face eviction this week. Which two will go? You decide.

Five housemates, one million dollars - the game really begins, but who's playing to win?

Still reeling from last night's double eviction, the time has come for the housemates to nominate for the final time.

Ryan has a hot tip, Bree has a hot pick, and there's one hot flick.

Tipping the scales, measuring the odds, and weighing in on the big issues.

Truth, lies, and the pursuit of happiness.

Roll in the sand, role playing, and roll the dice.

Housemates glam up and let their hair down as they celebrate the finest adult moments in the house. Who will win gold and who will win the booby prizes? It's a night of pashin' and fashion - it's the 2004 Big Brother Uncut Awards.

It's a fairy tale evening, but it ends in tears, and Prince Charming learns a thing or two about women.

Catherine, Paul, Ryan. Who goes? You decide.

The fab five become the awesome foursome and a shock announcement has Bree in the bad books.

With four housemates left and just seven days to go, Big Brother springs one final round of nominations on the house. They're unaware, but the eviction for these nominations is closer than they think.

Grumpy old men, silly young boys, and Bree sandwiched in the middle.

Girls become boys, boys become girls, and Paul puts it all down to biology.

It's Christmas in July, a tear in the eye, and lessons to live life by.

An emotional tear, a bum steer, and a new career.

Ryan, Paul, Bree. Who goes? You decide.

A shock exit throws the game wide open, and the result will change their lives forever.

Paul, Trevor, Bree. Who will be evicted at the final hurdle? You decide.

It's all come down to this: Bree or Trevor. Who wins a million dollars? You decide!
