The 2007 Australian Open was a Grand Slam tennis tournament held in Melbourne, Australia from 15 January until 28 January, 2007. The total prize pool was set at exactly $20 million (AUD), with the winners of both the men's and women's singles competition each receiving AUD$1,281,000. Over 500 players competed in 2007. The main draw for singles and doubles was released on Friday 12 January 2007. In Mixed Doubles, the scoring system was changed. Should both teams in a match become one set a piece, a match tie break will take part in the final set where the first team to score ten points wins the match. If the score for the match tie break become 9 9, a difference by two is required to win the game (e.g. 11 9, 12 10, etc).
