Brentwood Duo has already been predicted by Guy Sebastian to be good enough to win the X Factor Australia competition - and they're from New Zealand!
Isla and Finley Brentwood, siblings originally from Queenstown, wowed the judges in their auditions as they sang the Major Lazer and Ellie Goulding hit 'Powerful'. And the whole room stood to their feet, marking the first standing ovation of the X Factor AU season.
Judge Guy Sebastian commented after their performance "You could be exactly what the Groups category needs for their first ever X Factor win."
The siblings have had received international attention before when actor Ryan Reynold's shared their Deadpool song cover on Twitter.
The full Brentwood Duo X Factor Australia audition and judges' reaction will be broadcast on TV3 at 7pm on Sunday.
