Personal belongings
As in all Big Brother series, housemates have restrictions on what personal belongings they can bring into the house. They are each allowed to pack just one suitcase and one small bag to bring into the house. Many of the items they are permitted to bring in are at the discretion of Big Brother so all bags will be checked prior to entering the house and inventories of their contents will be compiled
Microphones and secrecy
Participants must wear their radio-microphones at all times during waking hours. Microphones can only be taken off in bed, in the shower and in the spa pool. If housemates attempt to communicate without the cameras or microphones recording the communication (eg tampering with microphones, writing secret messages, mouthing words off-camera) or if they try to tamper with, or cover recording equipment, then Big Brother reserves the right to expel them from the house.
Prior to entering the Big Brother house, the housemates are not allowed to talk to the media. Neither are they permitted to know the identities of their fellow housemates.
