During the period from 30 September 2016 to 3 November 2016, a series of unlawful communications occurred on multiple air traffic control (ATC) frequencies and the aircraft emergency frequency around the Melbourne area, Victoria.

Unlawful communications transmitted with malicious intent, while rare, have the potential to impact the safe operation of aircraft and, as demonstrated by this series of events, divert AMSA away from their core tasks.

Despite an absence of local instructions, ATC personnel were able to use best judgement to implement effective methods to quickly and effectively manage the unlawful communications to minimise the risk to flight safety.
