The council announced on Friday that the artwork will be painted over from November 20.

"Although this artwork holds significance to Sydney's Indigenous community, it was not commissioned as part of the Eora journey program that celebrates living culture of the Aboriginal and Torres Strait Island communities," the council said in a statement. "It was always intended to be a temporary piece."
