The new format will have a Survivor-style twist.

Australian reality TV fans haven't been able to contain their glee this week, with confirmation that old favourite Big Brother will get a reboot in 2020. And now, new details are emerging about what the fresh format will look like, almost two decades after season one's premiere in 2001.

An industry insider told Now To Love on Friday that live voting, which was an integral feature in earlier incarnations of the show , will be gone in the new series. Instead, in the format that was floated to several networks before reportedly being picked up by Channel Seven, housemates will vote each other out themselves, "Survivor-style", according to the source. While no host has yet to be announced, names rumoured to take the reins include original host Gretel Kileen as well as Mel Doyle, whose show Sunday Night was axed to make way for Big Brother's return.

TV Blackbox's editor Rob McKnight also detailed some of the other changes set to take place. Appearing on KIIS FM's Kyle & Jackie O show on Friday, Rob said the famous Big Brother house at Dreamworld on the Gold Coast may not feature this time around. "It doesn't look like they're going to build an actual house this year, it will be a house within a studio to keep costs down," Rob said, adding that the show will likely film inside a Melbourne studio. Production company Endemol Shine has already opened casting applications, with would-be housemates able to apply here
