If all the judges had given Sarah the same score of 9 each in the first round, she would have been 6 points ahead before the 2nd round started. And I feel that two judges were biased against her by giving her only 7 each whereas the other two judges gave her an 8 each for the 2nd round. For an important event like the Grand Finale, the fair thing to do is for the judges to do a blind taste test; in other words, they should not know whose dish that they are tasting. The judging in Masterchef Australia left much to be desired. 

Those scores were not fair!
