Big Brother is back tonight, and the house is in Bris-Vegas
Live nominations, a mystery button, six nights a week

Housemates, the house is open. Big Brother is back tonight, Monday 26 October, at 7.30pm on 10. Six nights a week from here.
The new house
It's moved to Brisbane, already nicknamed Bris-Vegas. New roof, new rooms, and a new Diary Room chair. Mel Tracina is back hosting.
The twists
Live nominations are back, and 10 says we get more say than ever from night one. There's a Mystery Button, and there's an eviction twist. Nobody's saying what either does.
Our take
A button nobody explains is going to get pressed in week one. We're calling it now.
Around ten housemates walk in tonight. All calls must be in before the doors open. Big Brother says so.
Who's the first one up for eviction?
