According to betting site Sportsbet, ahead of the TV show's premiere the four frontrunners are Taite Radley ($2.50), Todd King ($3.30), Charlie Newling ($4.50) and Robert Colangelo ($6.50).
So what do we know about Taite? Known as Dr. Phil amongst his circle of friends, the 28-year-old bank manager from Victoria is looking for a girl who is career driven and can make him laugh.
No stranger to reality TV, he has previously appeared on Channel 7 dating show First Dates.
And then we have Todd, Ali's actual knight in shining armour! The Perth sales rep, 26, is determined to be the prince charming Ali has been searching for.
"Hiking to the top of a mountain or scenic view with a full picnic basket and an IPod-dock playing old school RnB," he says of his ultimate date.
Another favourite is Sydney builder Charlie. When the 31-year-old builder from Sydney meets Ali Oetjen on the red carpet on night one of the dating show, he tells the blonde beauty that he wants to find true love, get married and have children.
It's what Ali wants, so he could be it!
We also have Robert, who has previously been in a serious relationship with Carly Bowyer from Married At First Sight. The 29-year-old plumber from Victoria who believes in love at first sight says he is ready to find his "queen".
