(a) an offence has been, is being, is about to be or is likely to be committed; and
(b) the use of a surveillance device is or will be necessary for the purpose of an investigation into the offence or of enabling evidence or information to be obtained of the commission of the offence or the identity or location of the offender.

(a) a Judge in any case; or

(b) state the nature and duration of the warrant sought, including the kind of surveillance device sought to be authorised; and
