CAAP 89O-1(2) - Published aerodrome information and reporting changes
Unlicensed aerodromes. Unlicensed aerodromes are not required, under the regulations, to provide aerodrome information to AIS or CASA and to have their aerodromes included in ERSA.
However, on request of the aerodrome operator, an unlicensed aerodrome used by aircraft with 10 or more passenger seats and engaged in regular public transport operations will be accepted in ERSA with full aerodrome information similar to that of a licensed aerodrome.
FAA: Now, from I remember, the airport surveys are good for 10 years. You are supposed to update or verify the survey at least every 10 years, or if there are any changes. This is up to the owner of the airport.
Every 10 years is a minimum, or if there have been any changes. 10 years looks at the vegetation and obstructions, and of course, the magvar.
Waypoints are reviewed on the AIRAC cycle, every 56 days, any changes are noted, but if there are no changes, waypoints can stay forever.
EDIT: update...
The Civil Aviation Safety Authority (CASA) Manual of Standards (MOS Part 139 Sect 7.2) and Sydney Airport’s Airport Operations Manual requires an annual instrument survey of approach, take off and transitional surfaces of all of our runways.
