Fare Thee Well is comprised of Laura-Lee Stevenson, 20, Jared Stevenson, 22, and Bethany Stevenson, 18.
They were the last group to perform in the groups section of the final bootcamp episode screened this week. Judge Willy Moon had to choose his top six groups out of the 12 that performed.
Fare Thee Well performed a version of Umbrella by Rihanna in front of a packed Vector Arena.
Their performance was so good Moon swapped them for Co-Lab, a band that had previously been given one of the final spots.
The six finalists in each category will now proceed to the judges' homes section where each judge will choose the three acts to represent them in the live studio shows.
