Viewers have taken to social media to share their dismay over the coach's revealing outfit.
"Someone should tell Delta and Sonia to do their shirts up. Seriously sick of seeing boobs - put them away - still sexy."
Another said: "Delta doesn't look like Delta tonight. Don't like the look at all."
One even slammed the stylist of the 'Wings' singer.
"Who the hell has styled Sonia and Delta this eve? Heads should roll."
However it wasn't all hate, many fans shared their love of Goodrem's maroon look.
This is not the first time the star has been criticised for her appearance on the talent show.
Goodrem was previously slammed for how she danced and pressed the buzzer during the blind audition rounds.
