So keen to keep it hush-hush, that even in the media preview (reviewed here) Seven has edited the details out.
All the network has revealed is that it features a “life-changing prize.”
Sitting at the top of Australian TV prizes is Big Brother 2004 when Trevor Butler won $1m dollars. There have also been two $1m winners on Who Wants to Be a Millionaire?: Rob “Coach” Fulton and Martin Flood.
On The Hothouse in 2004 Simon and Jules won a house on Bribie Island.
A number of TV contestants have won $500,000, including on Minute to Win It, while The Block contestants have won big bucks (Dan and Dani accrued $660,000 over two seasons) and there are plenty who have bagged $250,000.
I rather like the theory that House Rules may pay off someone’s mortgage, although the money for a home owner in Sydney would vastly outweigh those in WA.
Any other theories?
