According to the Herald Sun, only 2.568 million people tuned in to watch Kate Bracks go head-to-head with Michael Weldon and be crowned the winner of the cooking reality show last night.
When Adam Liaw won last year's series there was an audience of 3.964 million viewers, while 3.74 million people watched Julie Goodwin defeat Poh Ling Yeow in 2009.
Some fans have complained that Channel Ten decided to split the final episode into two parts, airing new reality TV show The Renovators for an hour in between. The first part of the MasterChef finale averaged 2.334 million viewers.
