The reality television show, which debuted in 2001 but was axed in 2008, will return to Aussie TV screens later this year, this time hosted by former Dancing with the Stars presenter Sonia Kruger.
Big Brother producers will hit the road next month for an extensive "housemate hunt", The Daily Telegraph reports, with casting calls in all the country's largest cities.
The search starts at Penrith Panthers in Sydney on April 29.
Big Brother executive producer Alex Mavroidakis said that they are hoping to find "people who have warmth, intelligence, humour and no agenda. It's the man on the street, the girl next door.
"Do not try to second guess what we are looking for. The truth is there is no Big Brother type. Be yourself, be engaging and you might just win us - and Australia - over."
Kruger recently revealed that the rehashed version of the show will see the "return of all that is good about the format - a mix of big event television, totally watchable Australians, engaging conversation and most importantly, humour".
Filming for Big Brother is scheduled to begin in late August in a brand new house that will soon be built at Gold Coast theme park Dreamworld.
