With three original Housemates gone, there’s room for a new face and this Wednesday we will meet Big Brother’s latest Housemate! A new Housemate is guaranteed to shake things up.

The girls admire Leo's body while he works out at the gym, but Lisa is not buying what he is selling. The Housemates have passed this week's Yes/No challenge, which continues providing many hours of entertainment for the Housemates. David dons a superman t'shirt and gets hitched to a wire in the backyard and takes a quick flight! Meanwhile, Priya thinks that Leo has had a strong start, but maybe he has played all of his cards to soon. She thinks some of the Housemates might be threatened.

Tonight on Big Brother, one Housemate is saved and one Housemate will leave the Big Brother House for good. Cougar Cat tells Big Brother she knows her feelings for Lawson have caused her problems and that she’s been selfish. Cat and Lawson find out all the Housemates thought their decision to spend the night together in the Sanctuary was a bad idea. Big Brother gives Cat a task called “The Hotel”. Cat is allowed to choose six Hotel Guests and she chooses her fellow nominees, the remaining Housemates must be the Hotel staff. The Hotel staff must stay in staff quarters, and cater to every whim of the Hotel Guests, as you would expect in a 5-Star Hotel.

TONIGHT Big brother from holidays to hell days, The Hotel's Staff are quickly turning on their Guests!

Tonight Big Brother will hand Cat her Power Play, presenting her with two DVDs, one marked “Big Brother’s Secret” with footage of all housemate nominations. The other is marked “Your Secret” and contains the footage from Cat and Lawson’s night together. Cat is permitted to watch Big Brother’s secret, but only if she allows the rest of the house to watch hers. As the vision also features Lawson, he is called to the Power Room to make the decision with Cat.

The Sanctuary's secrets are spilling over into the House

Sonia Kruger returns to the live stage to deliver an update of the House in the 24 Hours past including nominations. A massive power play will see Skye as Head of House given the ULTIMATE POWER. She will be given the opportunity that's never-before-done in Big Brother history, will she be quick enough to use her power wisely? And for the first time this year the Housemates are delivered their nominees for eviction LIVE from Sonia. This is the first week Intruder Leo can be nominated, and in order to allow Marina time to settle she will be immune. And how is our fake evictee getting along in the Sanctuary with Ben on the secret mission?

Still missing from the House is the fake evictee who has spent the entire week in The Sanctuary on Ben's secret mission. Next week the Housemates will be delivered a double shock as this person will be allowed to re-enter the House.

Tonight on Big Brother, the House has spoken and this week will see seven Housemates up for nomination. Then the Housemates watch Jason’s parting message, which leaves a few of them rattled, particularly Cat and Lawson. Jason said “it was them (Cat and Lawson) causing the most disharmony in the House.” Is there another love triangle starting to emerge or is it just Marina ruffling some feathers. Leo and David discuss #Trasha and wonder how strong Aisha feelings really are for Travis.

Look out! The HMs Learn There are Neighbours Next Door! But just who is crashing the party? After arriving together in the Sanctuary, the four new neighbours were rowdy, excited and boisterous and eventually, the existing Housemates cottoned on that something BIG was up.

Things turn red hot in the House as Big Brother plays back to the Housemates their biggest secrets. The fallout from the revelations of each Housemate is massive.

In Big Brother’s biggest eviction this year, three Housemates will lose their spot in the finale and their chance at winning $200,000. Intruders Penny and Lina, along with original Housemates Priya, Ryan, Travis and Skye, will battle it out for a place in the final 24 hours of Big Brother 2014.
