Rival betting agency TAB is also predicting Shaynna's victory and at $1.20, making the win even more likely.
Behind Shaynna, the next most likely to win is Married At First Sight's Martha Kalifatidis, with Sportsbet placing her odds at $4.00 while TAB has her sitting at $5.50.
Bizarrely, TAB has Michelle Bridges' odds at $1.01, despite the fitness queen having already been booted from the competition.
Of the current Celebrity Apprentice line-up, both betting sites’ odds suggest Josh Gibson and Ross Noble the least likely to win, although UK comedian Ross has better odds than Josh on both sites.
Already fired from the competition are big contenders such as The Veronicas, Anthony Callea and Survivor star and international model David Genat.
Throughout the season, plenty of drama has ensued, with an intense feud between Camilla Franks and Ross Noble, and also between Michelle Bridges and David Genat.
Twin sisters Jess and Lisa Origliasso, otherwise known by their band name The Veronicas, were also involved in an on-screen spat, where one accused the other of being a “bit much”.
And as the show reaches its dramatic conclusions, we can only assume tensions will reach breaking point.
