Flocking to Sportsbet, BB fans have currently placed odds on Ellie Gonsalves to take out top spot, with odds of 1.83. In runner-up position, according to the website, is Luke Toki, with odds of 2.40.
While TAB has predicted the same top two, the gold and silver positions are switched, with the website placing Luke in top spot (1.75) and Ellie in second (1.80).
Meanwhile, both websites have listed Josh Carroll as the predicted second runner-up, both with odds of 6.00.
Ellie, - who is an actress, model, and entrepreneur - is competing for the Wildlife Warriors charity.
The Aussie was named a global ambassador of the charity, which was founded by Steve and Terri Irwin, in 2010 after visiting Australia Zoo and walking through the Wildlife Hospital.
"It's heartbreaking but really does make you want to make a difference as well," Ellie said at the time.
It's clear that the zoo is a special place for Ellie, having recently got engaged to her partner Ross Scutts at the Wildlife park itself.
Meanwhile, Luke Toki, who was the self-appointed King Of The Jungle on Survivor, is playing for Perth Children's Hospital Foundation for Cystic Fibrosis Clinical Research.
It's a cause that is close to Luke's heart as his youngest daughter, Madeline, was diagnosed with cystic fibrosis shortly after being born. The reality star also has two sons, Lennox and Nate, who have autism and autistic traits respectively.
The predicted second runner-up, model Josh Carroll, is playing for the not-for-profit Keith's Closet which works to provide quality clothing, toiletries, sanitary items, and more, to mental health patients admitted or discharged from hospital.
So, have BB viewers correctly predicted the final standings? We guess we'll have to wait and see.
