Differences from ICAO SARPS
Sydney - SW Sector trunk Drainage
Changes to Darwin CTA
Darwin Traffic Management Plan
ADS-B Trial Bundaberg
Sydney - Guard Light Project
Melbourne - Northern Apron Works
Broome NDB & DME Relocation
Gold Coast INDI 300 Motor Race
Bathurst Motor Races
hardly the sort of topics that need a piece of paper sent to every pilot who is getting documents from AsA. The less I get the better. Some of that stuff is really in the realm of Notam material.
