RAA (Inc) signed an annual update which incorporated changes; we used to get one of these books, each year, that was the 2010 edition. I would assume that RAA Ltd gets these books and signs each year, and if so would be working to the 2025 or 2026 Edition which would incorporate andy changes like you mentioned.
One of the sure signs of Self Administration is reference to Australian Standards, in this case AS3806. - 2006, and International Standards - ISO 23100 (International Standard 23100 covering Risk Management, and the Organisation's SMS (Safety Management Standard).
These were never mandatory and we never took much notice of them, but they are industry benchnarks and compliance with an industry benchmark is good to have in a case where someone is making a claim against you, so Australian Standards have become elevated in daily use. Same with ISO. We put them in our Operating Manuals.
Where they become vital is for RA operations, specifically "Ultralight Exceptions" to the CASA Regulations.
