LeadSled...
I have no way to verify, I don't have time to go through all the ICAO Docs., but I was recently told that Australia now has almost 2000 differences.
With the greatest of respect LeadSled, differences aren't actually published in ICAO Docs. They're published in the Supplements to the Annexes.
To save you time and bother looking through the Supplements to the Annexes, Australian differences are summarised in AIP Supplement H22/10 at:
Airservices Australia - Aeronautical Information Package (AIP)
I don't think there's 2,000 differences listed in the AIP SUP.
However, having said that, there still seem to be a huge amount of published differences for a Contracting State such as Australia, and which therefore seems to reflect the effete regulatory authority (CASA) that we are cursed with, and which seems to be totally incapable (unwilling or intransigent may be more accurate?) of making any headway whatsoever in accomplishing any meaningful regulatory reform that will/can align Australia's civil aviation regulations with 'best practice'.
