The 20-year-old Australian model, who will compete in the final of the beauty pageant in the Bahamas on August 23, has said that she cannot pick who will be her biggest competition on the night.
Finch told the Herald Sun: "Any one of these women could easily walk away with the title."
Sportingbet Australia has Finch sitting at equal favourite with Miss Mexico Karla Carrillo. She is also rating higher at the same stage of the judging process than 2004 Aussie champion Jennifer Hawkins.
Finch's roommate at the contest, Miss USA Kristen Dalton, is currently in seventh place with betting shops. Bookies say that Miss Great Britain, Clair Cooper, stands little chance of winning the title.
On beauty websites, Finch has been consistently rated in the top ten by industry experts.
