Sydney Airport
In 1995 the Australian Government passed a law through parliament called "The Sydney Airport Curfew Act". This limits the operating hours of the airport. This was done in an effort to stop complaints about aircraft noise. The curfew disallows aircraft from taking off or landing between the hours of 23:00 and 06:00. However, some special flights are allowed between 23:00 to midnight and 05:00 to 06:00, by Section 12 of the Act.
