After multiple reboots — and a bunch of icons taking on hosting duties — Big Brother Australia has officially returned with Mel Tracina wrangling the vibes. So, to get you hyped on this chaotic reboot, here’s the full housemates list for Big Brother Australia 2025.

Returning to both Network 10 and the Gold Coast’s Dreamworld, Big Brother Australia has risen from the ashes like a phoenix for another raunchy reboot.

This time around, Network 10 is hoping to tug on the heartstrings of OG fans as well as trying to rein in some new recruits into its global fanbase.

So, with a hunt for everyday Aussies, which includes a primary school teacher, a barber and a mama’s boy, here are our OG 12 housemates for Big Brother Australia 2025.

Who is in the Big Brother Australia 2025 cast?

Edward is a bloke who has a hair cut every Friday who froths a sit down shower to Akon‘s discography. Honestly, relatable, but I’m more of a Ne-Yo gal.

The 13th housemate will be revealed in episode two of this reboot.

At the time of writing, we’ve only just copped the premiere episode so the cast list will grow with the 13th bombshell entering — I mean the 13th housemate entering Big Brother‘s humble abode.

Also… there could be intruders throughout the season.
