A Kiwi brother and sister act have won praise and applause with an acoustic performance on X Factor Australia, which returns to TV3 this Saturday.

The harmonies of Brentwood Duo's audition left the judges in "total shock", says Australian broadcaster Seven Network, which could herald a successful run on the talent show.

Finley and Isla Brentwood were raised in Queenstown but currently reside in Melbourne, and were featured on the Deadpool soundtrack after catching the attention of Ryan Reynolds.

Now they're a hit in Australia, if the cheering X Factor crowd is anything to go by.

"Wow!" exclaimed judge Guy Sebastian, later describing their voices as "insane".

Fellow judges Iggy Azalea and Adam Lambert both nodded their heads along merrily to the music.

"Oh! Brentwood Duo singing the harmonies," beamed host Jason Dundas.

The full Brentwood Duo X Factor Australia audition and judges' reaction will be broadcast on TV3 at 7pm on Saturday.
