The show's longtime narrator, who has been part of the reality TV juggernaut since its 2001 debut, says its appeal lies in watching people from different walks of life form friendships and challenge their assumptions.
Goldman said the beauty of the reality program was seeing a "hardcore right-wing person that watches Sky News every night" and someone who's a "full all the way lefty ABC lover" come together on common ground.
"Those people from those different walks of life very rarely meet and very rarely spend the time to figure each other out," he said.
"Whether it's someone who might be considered a bit sexist or someone who's a bit of a feminist, or someone who's a surfer, and someone who's a farmer ... these people are being shoved in this social experiment called Big Brother."
For viewers, watching those relationships unfold can challenge their perceptions of people they might not otherwise encounter.
"And I think what that does for societies, people watching it, they go, 'I understand that person now'."
After its successful return in 2025, Big Brother is back on Network Ten in October, reviving the original format with live evictions, live nominations and live streaming.
The show's return attracted a new generation of gen Z viewers while reconnecting with millennials, gen X and baby boomers.
The finale drew a record 1.1 million viewers, making it Ten's biggest reality show since 2023.
Over the years, former housemates have gone on to become familiar faces in Australian media, including radio presenters Ryan "Fitzy" Fitzgerald and Chrissie Swan, influencer Skye Wheatley and Neighbours actor Blair McDonough.
For some viewers, Goldman said, the show's appeal lies in seeing their experiences reflected on screen.
He recalled fans connecting with housemates such as 2025 winner Coco Beeby, who reminded one viewer of their mother, who raised three children on her own.
"You don't feel so alone if you see someone else like you out there that's doing the same thing, going through the same issues in life, and enjoying the parts of your life that should be celebrated," he said.
As for what viewers can expect from the new season, Goldman said the mix of personalities made the show impossible to predict.
"You never know until all these different flavours are thrown together and you taste it in the Big Brother milkshake," he said.
"It'll taste like liquid gold."
Goldman predicted the new season would be the show's "most successful" yet.
Big Brother Australia 2026 premieres on Monday.
