The 'Innocent Eyes' singer is the latest famous face to be added to Darling Harbour's new Madame Tussauds museum. Dannii Minogue was the first celebrity to show off her double at the new venue in February.
"It's amazing," Goddrem said upon seeing the waxwork. "I wasn't involved in the creation. That would have been a disaster."
The 27-year-old, who will appear as a coach on the Australian version of The Voice, joked: "I'll stick to music."
Sixty artists spent more than 800 hours working on the waxwork, which sports a dress Goodrem wore on her 2005 'Visualise' tour.
"It brings back happy memories from one of my favourite tours and I'm so happy to have such a proud moment of my career immortalised in an Australian hall of fame," she said.
Goodrem - who split from boyfriend Joe Jonas earlier this year - recently debuted the video for her new single 'Sitting On Top of the World', the first track taken from her upcoming fourth album.
