“The Civil Aviation Regulations 1988 (CAR) and Civil Aviation Orders (CAOs) are available on Federal Register of Legislation. CAOs support the CAR. They will be progressively removed as we move to the CASR. Associated guidance is provided in Civil Aviation Advisory Publications (CAAPs).”
I have logged onto www.legislatio.gov.au then searched CAOs . No result search . Where to find ?
Perhaps you are making things harder than necessary for yourself..
Start at the CASA page.
Then link to Rules and Regulations
.. then Current Rules .. or go direct using this link - https://www.casa.gov.au/rules-and-regulations/landing-page/current-rules
This page contains a bunch of links to the various rules and related documents. A very useful data source.
