After Wednesday's shock eviction of audience favourite Daniel Hayes, Big Brother Australia is down to its final four housemates.
But out of Marley Biyendolo, Ari Kimber, Christina Podolyan and Sarah Jane Adams, one contender is the clear favourite to win it all, according to multiple Australian betting sites.
As of Thursday, both Sportsbet and TAB had 26-year-old basketball player Marley as the short-odds favourite to walk away with the show's $250,000 prize.

SportsBet had the Melburnian at $1.60 to be the last man standing in the house, with Christina lagging behind at $2.90.
Sarah Jane and Ari are at long odds to win, at $7 and $12 respectively.
Rival betting agency TAB meanwhile has Marley at even narrower odds of $1.50.

Daniel Hayes, who was sent home on Wednesday's episode, attempted to convince Big Brother to let him save evicted housemate Tilly Whitfeld - and bag himself an early exit and guaranteed payday in the process.
