Ms Hall had been in an induced coma since Thursday when she was rushed from Allianz Stadium in Moore Park to the hospital in a critical condition.
It is understood she had been climbing over chairs before she slipped and fell down six rows of seating.
Paramedics were called to the stadium about 10.15pm on Thursday following reports a woman had fallen.
Williams’ concert ended at about 10pm when the 40,000 odd fans began to exit, about the same time when Ms Hall began climbing over seats and fell
She suffered serious head and face injuries and was treated at the scene before being taken to hospital.
The sold-out show kicked off just after 7pm and had wrapped by about 10pm when the 40,000 fans began making their way to the exit.
It was around this time the woman began climbing over the seats and fell.
Williams’ will return to the stage at Melbourne’s AAMI park on Wednesday night after taking a week off his XXV Australian Tour.
The next two nights will mark the end of the largely sold-out tour which included spots at wineries in Queensland, Geelong and Perth.
