Big Brother returns to Channel 10 on 26 October with mystery-house twists – The next season of Big Brother begins on Channel 10 at 7.30pm on Monday 26 October, with the network promising a Brisbane house designed to surprise its new residents.
Network 10’s latest promo describes a “house of mystery and mayhem”. It teases twists around nominations and evictions, pranks within the house and more power for viewers from the first night.
The premiere date gives Australian fans a firm start time after the network’s earlier announcement that Big Brother was moving into a new Brisbane home. The new alert is about the format’s on-air return; it does not yet name the housemates or set out the voting rules.
What has Channel 10 revealed about the house?
Network 10 says the housemates should not assume that what they see is reliable. The broadcaster is keeping the detail of its “mystery and mayhem” theme under wraps, but says the house itself will play a part in the surprises.
“Everywhere the housemates turn, the house turns on them,” Big Brother says in the new alert. The network also points to a nominations twist, an eviction change and pranks throughout the season.
For viewers, Channel 10’s most notable promise is greater influence from night one. Exactly how audiences will exercise that power remains to be explained, so any assumptions about voting, feeds or specific live elements would be premature.
Brisbane setting and the 26 October premiere
The programme’s move to Brisbane was previously announced as part of Network 10’s plans for the 2026 season. The new campaign leans into the city, with the broadcaster joking that the season has more turns than a drive to Mount Coot-tha.
Big Brother has long centred on a group of housemates living under constant observation. The 2026 campaign keeps that premise but is positioning the redesigned house and audience participation as key points of difference.
Network 10 says the programme will be available to watch on Channel 10 and stream free through its digital service. Viewers should check local listings and the service for episode availability after the premiere.
