What is the primary regulatory authority for civil aviation in Australia?

The primary regulatory authority for civil aviation in Australia is the Civil Aviation Safety Authority (CASA). CASA is responsible for the regulation of civil aviation safety in Australia, which includes overseeing the licensing of pilots, the registration of aircraft, and the enforcement of safety standards. This authority works to ensure that civil aviation operations in Australia comply with national and international safety regulations.

In contrast, the Australian Transport Safety Bureau (ATSB) is focused on transport safety investigations and cannot be classified as a regulatory body; its role is to investigate transport accidents and incidents to improve safety outcomes. Airservices Australia is primarily responsible for providing air traffic control and navigation services, rather than regulating aviation safety. The Federal Aviation Administration (FAA) is the regulatory authority for aviation in the United States, not Australia, thus not applicable in this context.
