Top 24
The Top 24 were revealed on 5–6 May 2015. Prior to the first competition round, Mario Montecuollo was disqualified after his five-month professional kitchen experience violated the show's guidelines of the auditions. The producers investigated the contestant's position as a head chef at his bar in Enmore and discovered that Montecuollo had been working one day a week as a paid cook for five months within the past years. Casual participants were allowed to audition without working previously in a professional kitchen for more than six weeks, ruling him ineligible to compete in the show. He was replaced by Jessie Spiby, who unsuccessfully advanced to the Top 24 in the second episode.| Contestant | Age | State | Occupation | Status |
