Perspective,
You are missing a few things:
The CAAct itself.
CASRs 1998,
Advisory Circulars
Between 4 and 5000 Legislative Instruments that vary the regulations.
Manuals of Standards, MOS, thousands of pages of them.
CASA Policy letters --- of very doubtful legal enforceability
etc, etc.
It would be an interesting and ultimately futile exercise to try and compile a definitive list, in order of precedence.
Australia's aviation regulations are a convoluted, complex and contradictory mess and getting worse by the day.
Tootle pip!!
