Many of these 'airports' have no effective boundary and are best
represented by a node.
Some are 'operated' by the local council and the council owns a large
area of land around the 'airport'.
Some may be 'operated by the local station (in American 'ranch') and
they may own some 100s of miles around the 'airport'.
These 'operators' see little point in paying scarce money to fence in
the 'boundaries'.
Many of them have no 'regular commercial' flights, some have regular
postal deliveries (by plane), some have the Doctor fly in (google Royal
Flying Doctor Service).
For the state of New South Wales you may find the LPI Base Map usefull
to find the legal boundaries, those may not exist for some of these
'airports'.
I would not be too anxious to add closed ways for these 'airports'. Few
people use them.

Yes. We do not have other signals. It is possible to miss official
bounding box (when it is hard to see fence or when there is no fence
at all), but it will be close enough and it will represent airport
area. I could see that couple of airports have really rough
approximation of the boundaries.
Thanks,

Hi.
That seems like a good idea. How will you know the bounds of the
airport? Just from aerial photos?

Hi everyone,
We would like to manually add polygons around airports in
whole Australia. We have added polygons for very few airports
that were marked just with a single node.
By using THIS <https://overpass-turbo.eu/s/Pe6> OverPass-Turbo
link, you can see that there are nearly 1,200 airports that
needs to be inspected.
We could recognize that other map competitors have properly
marked most of these airports as polygons.
Anyway, we have doubt should we add polygons in the following
situation(s):
https://www.openstreetmap.org/way/73310214
There are no control tower nor any other buildings. It has a
proper name Kulin Airport @-32.6721992, 118.1689987.
Should we add a polygon in such cases?
Please note that *we won’t add any polygons* if the
airport/airstrip/runway is on the water.
Umm some of the 'water' is very intermittent .. to the degree that
farmers plough it and plant crops on it.
We believe that there is no need to preserve both way and a
node of the same feature. Especially because that node is
somewhere at the center of the airport and it doesn’t
represent entry of the airport area or entry of some building.
Example should be Hamilton Airport @
https://www.openstreetmap.org/node/407705915
<https://www.openstreetmap.org/node/407705915>. We would merge
existing node of the airport in to polygon of the same polygon
and we would remove tags from the merged node.
If we are adding new polygon, we would preserve existing
airport node by keeping this node as a part of the new polygon.
Thanks in advance for the answers!
Merry Christmas and Happy New Year,
Nemanja
