Melbourne GP sound levels?

Does anyone who might know tell me if maximum sound levels are a thing? I was at Albert Park today, and before qualifying, Botas was going to take a V10 F1 out for a couple of laps. I was super excited to finally hear an F1 screaming again, but to my dismay, he barely opened it up, was just puttering around, a Honda civic with an exhaust would be louder. Also, we used to have an FA-18 Super Hornets do a flyover too, that's been gone for a number of years too. Is this just a nanny state Australian thing, or is this global? Not happy paying $900 aud for a grandstand ticket and getting everything watered down.
