On and after VCAT gives notice to an administrator under section 130(1), the former missing person or that person's personal representative (as the case requires) is bound by, and may take advantage of, any act done on behalf of the missing person by the administrator within the powers conferred on the administrator by VCAT as if—
(a) the act had been done by the missing person; and
(b) the missing person had decision-making capacity to do the act.
