(1) On commencement, a requirement in an existing supervision order that a supervisee must not commit a serious sex offence or an offence of a sexual nature is taken to be a requirement that the supervisee must not commit a serious sex offence or an offence of a sexual nature as those terms are defined after the commencement.
(2) However, a supervisee does not contravene a requirement of the supervisee's existing supervision order if, before the commencement, the supervisee committed an offence that was not a serious sex offence or an offence of a sexual nature at the time the offence was committed.
(3) In this section:
"existing supervision order "means a supervision order that was made before the commencement and is in force on or after the commencement.
