Airservices Australia is an organisation dedicated to community and government airline services for all states and territories in Australia. It includes a dedicated service line to note complaints of excessive noise caused by planes.
In 2023 a whopping 20,716 call-in complaints came from a single Perth man complaining about the noise around the city's airport. Airline Australia's noise complaints and information division received a total 51,589 complaints relating to excessive noise around flight routes and airports.
Airservices Australia's complaint call-in time is 10am to 4pm on weekdays only. This equals to 76 calls a day or around an insane call every 6 MINUTES when phone services are operable.
It is not known if the services in Perth Airport have changed, but the larger Air Noise Ombudsman has not undertaken any investigations around the matter at Perth Airport. It's safe to assume the answer is no. It goes to show that complaining excessively does not guarantee you get what you want.
Most of you have made the acute observation that sometimes strange warnings exist in odd places. Heavily implying someone has attempted the prohibited activity to warrant the warning sign.
