Australian Security Intelligence Organisation Act 1979

In addition to the things that the Organisation is authorised to do that are specified in a questioning warrant, the Organisation is also authorised:

to remove and retain any record or other thing produced by the subject of the warrant while before a prescribed authority for questioning under the warrant, or to retain any record or other thing seized under subsection 34CC(5), for the purposes of:

inspecting or examining the record or thing; and

in the case of a record—making copies or transcripts of the record; and

to do any other thing reasonably incidental to:

the things mentioned in paragraph (a); or

any of the things that the Organisation is authorised to do that are specified in the warrant.

A record or other thing retained as mentioned in paragraph (1)(a) may be retained:

if returning the record or other thing would be prejudicial to security—only until returning the record or other thing would no longer be prejudicial to security; and

otherwise—for only such time as is reasonable.

A seizable item seized by a police officer under subsection 34CC(4) may be retained for such time as is reasonable.

A communication device seized by a police officer under subsection 34CC(4) may be retained:

if returning the device would be prejudicial to security—only until returning the device would no longer be prejudicial to security; and

otherwise—for only such time as the prescribed authority before whom the subject is appearing for questioning under the warrant considers reasonable.
