Hell, I am all for a curfew. Preferably one that ends at 0900. Aircraft noise affected areas in BNE have a legitimate complaint in my view. The ridiculous STARs with their low level nav exercises add to noise, as do early speed reduction targets which mean early flaps and more aero noise.
The larger agenda you guys are missing is the carbon one. A 60% reduction in carbon in 7.5 years is not going to leave any industry or transport mode unaffected. 60% is what some teal independents are talking about. The political dialogue is soon going to be all carbon, all the time.
Global carbon reduction targets are going to be missed by a wide margin, yet our industry's noise is still going to become our least troublesome emission.
