The network's latest advertiser-facing update says the reboot will be live, unscripted and on air six nights a week during the key retail period.
Paramount ANZ is pitching the format as a high-frequency audience play, with access across screens and a strong connection to viewers who shop around major sale periods.
The update says Big Brother's 2025 return delivered a national total audience of 838,000, reached 6.7 million viewers, and ranked number one in its timeslot for 25 to 54s and 16 to 39s.
That follows 10's earlier confirmation that Big Brother would return in 2026 with Mel Tracina hosting and another group of housemates entering the game.
The 2026 season is expected to continue the revived format's focus on live nominations, evictions and feeds, keeping the franchise closer to its original Australian reality TV roots.
Paramount has not yet announced a viewer-facing premiere date, housemate list, or full broadcast schedule for the 2026 season.
For now, the clearest official signal is that Big Brother will be a major Q4 priority for 10, with more consumer-facing details still to come.
