Big Brother Australia 2025 – Premiere Date, Host and Schedule

Network 10 has officially revived Big Brother Australia, confirming a 2025 season that returns the reality franchise to its original broadcast home after cancellation by the Seven Network. The series premieres Sunday, November 9, 2025, introducing a new host, restored live elements, and a return to the Dreamworld compound on the Gold Coast.

The 2025 iteration marks the first time the format has aired on Channel 10 since the show concluded its initial run in 2008. Following four seasons on the Seven Network between 2020 and 2023, the program faced cancellation in 2024 due to declining viewership, prompting the rights to revert to Paramount-owned Network 10.

Production has constructed a new, larger set at Dreamworld’s Exhibition Centre, the same location that housed the original 2001-2008 seasons. This relocation accompanies significant format adjustments, including the reintroduction of live nominations and public voting mechanisms that were absent in recent iterations.

Is Big Brother Australia Returning in 2025?

Network 10 formally confirmed the series’ return on September 16, 2024, during its annual upfronts presentation. The announcement followed months of speculation after Seven Network executives indicated in early 2024 that the program would not continue on their platform.

Key developments surrounding the revival include:

• Return confirmed by Network 10 on September 16, 2024, following Seven Network cancellation
• Network transfer from Seven (2020-2023) back to original Channel 10 home (2001-2008)
• Mel Tracina appointed as host, replacing previous presenter Sonia Kruger
• Production relocated to Dreamworld Exhibition Centre, Gold Coast
• 13 housemates confirmed for the initial cast
• Live nominations and Sunday evictions restored to the format
• 24/7 livestream access available via digital platform

When Does Big Brother Australia 2025 Premiere?

The season launches Sunday, November 9, 2025, at 7:00pm AEDT. This scheduling places the premiere during the final quarter of the television ratings year, a strategic positioning that allows the program to build momentum toward the summer period.

Weekly Broadcast Structure

Episodes air six nights weekly, with no Saturday broadcast. Sunday episodes commence at 7:00pm AEDT and feature live eviction ceremonies, while Monday through Friday episodes screen at 7:30pm AEDT. Programming continues uninterrupted through major events; for instance, the broadcast proceeds as scheduled on November 19, 2025, following the ARIA Awards red carpet coverage.

Who Is Hosting Big Brother Australia 2025?

Comedian and broadcaster Mel Tracina assumes hosting duties for the 2025 season, marking a departure from Sonia Kruger, who fronted the Seven Network iterations from 2020 through 2023. Network 10 confirmed Tracina’s appointment during its 2024 upfronts presentation.

Mel Tracina’s Background

Tracina brings experience from The Cheap Seats and Nova Radio to the role. Her selection signals a tonal shift for the franchise, emphasizing comedic commentary alongside traditional reality television hosting duties. Sonia Kruger, who guided the series through its Seven Network tenure, is not involved in the Network 10 production.

The Voice of the House

Leon Murray returns as the voice of Big Brother, reprising his role from the 2008 and 2012-2014 seasons. His involvement reinforces the production’s emphasis on returning to the show’s heritage elements while incorporating contemporary twists.

Who Are the Big Brother Australia 2025 Housemates?

Network 10 has confirmed that 13 housemates will enter the compound at launch. No specific contestant names, ages, or biographical details have been released as of the premiere date. The casting reflects the standard demographic diversity expected from the franchise, though producers have not disclosed whether any returning contestants from previous seasons feature in the initial lineup.

Where and How to Watch Big Brother Australia 2025?

Viewing options span both traditional broadcast and digital streaming, with Network 10 leveraging its 10Play platform to restore the 24/7 livestream feature that defined the show’s early seasons.

What Details Are Confirmed vs Unclear?

Why Did Big Brother Australia Change Networks?

The 2025 transfer to Channel 10 follows the Seven Network’s decision to cancel the franchise in 2024 due to sustained ratings declines. The Seven iteration, which launched in 2020, underwent multiple format alterations—including pre-recorded episodes and modified nomination procedures—that failed to retain audience share compared to earlier seasons.

Channel 10, which housed the original Big Brother Australia from 2001 through 2008, has positioned this revival as a return to authentic formatting. The reinstatement of live nominations, public voting, and continuous streaming represents a deliberate rejection of the Seven Network’s later production choices.
