Big Brother 9 (Datria)

Big Brother 9 was the ninth season of Big Brother in Datria. The season was confirmed by Channel 7 on September 27, 2009, more than a month after Big Brother 8 concluded. Auditions were held from November 30, 2009, until March 2, 2010. The season premiered on June 13, 2010, and ended on August 21, 2010, lasting for 70 days. After 10 weeks, Natalie Frenkel prevailed as the season's winner over Hannah Ortolani and Joice Schoon by a 5-2-0 vote. The final two of Hannah and Natalie marks the first time in the show's history that all of the finalists were female.

Twists

 * The Saboteur - Before entering the house on day one, a housemate was told that they were Big Brother's saboteur. Over the course of the game, the saboteur would be performing various tasks that were requested by the viewing public. For every task the saboteur completed, they would receive an increasing value of money, up until they were evicted.
 * Intruding Housemates - During the first few weeks, whenever a housemate was evicted, a new housemate would enter the house to replace them. The intruding housemate would also be immune from their first eviction. The latter rule did not apply to the intruding housemates who entered in Week 6.
 * Double Eviction - During Weeks 6 and 7, the housemates were told that the week was a Double Eviction week. Two people would be evicted from the house by the end of the week, one by the middle, and the other by the end.
 * Finale Week Eviction - For only the second time in the series's history, an eviction was held during the final week. In a format similar to a double eviction week, the three remaining housemates competed in the final Head of Household competition throughout the first half of the week, with the final eviction taking place halfway through the week. The finale would follow afterwards several days later.
 * Final Two - Shortly after Elijah Duchin's eviction, Abby Espenshade had decided to pull herself from the game. As a consequence, there would be only be two finalists instead of the original three in order to make up for the unexpected exit. This also had the consequence of effectively nullifying Abby's vote in the jury in order to keep the jury at an odd number of votes. This is the second time that a final two was used without it being intentional, a situation that previously occurred in Big Brother 5.
