Nine sources have confirmed to TV Tonight that their option on Big Brother expires this week with the network not looking to resume production on the much-talked about reality series.

That clears the way for another network to move on the show with industry rumours swirling Seven is eager to proceed. A casting notice from Endemol Shine was also posted earlier this month.

The timing is very fortuitous for Seven with its Upfronts due to take place on Wednesday afternoon (one more calendar week and Nine could have thrown a spanner in Seven’s presentation plans….).

Former host Gretel Killeen refused to rule any involvement in or out when recently asked. Former runner-up Chrissie Swan has called it her “dream job.”

With FOX Studios unavailable for filming, all eyes are on Seven’s own Eveleigh production facility as one probable home, should the network confirm production on Wednesday.
