DR650,
"We" have been working on a Part 135 (and 121, no 125) since 1997, so far it runs to more pages than the whole NZ regulations, it has no completion date.
Have a look at Part 61 including Manuals of Standards for a good example of "The Australian Way". All up, something over 2000 pages, with the accompanying CASA compendium of policy interpretations.
Tootle pip!!
