In response to complainants raising concerns about helicopter movements during the curfew, Airservices investigated all helicopter movements to and from Adelaide Airport between 1 July and 30 September 2016. The investigation found that in each case these movements were emergency services helicopters which are permitted to use the airport during the curfew period.

The curfew applies only to aircraft arriving at or departing from Adelaide Airport. Aircraft travelling between other origins and destinations are permitted to fly over Adelaide during curfew hours.
