The Transport Security Regs require a holder of a Flight Crew Licence to have a current security check ie ASIC or AVID
So based on TSR reg 6.55 para (3)(a) below, you don’t necessarily need an ASIC, but need a Security Status Check at least every 5 years!
(2) ……..a person who is over 18, and holds a security designated authorisation, must not perform a duty that is essential to the operation of an aircraft while the aircraft is in Australian territory unless:
(a) his or her aviation
security status check is current; or
(b) he or she has requested an aviation security status check.
(3) For paragraph (2)(a), a person's aviation
security status check is current at a particular time if:
(a) it was carried out no more than 5 years before that time; or
(b) he or she has requested that a new check be carried out; or
(c) within the previous 2 years, he or she underwent a background check for the issue of an ASIC.
