[talk-au] Melbourne Airport (mapped as both node and way)

[Andrew Harvey]

@John I sympathies with your concern, but we can't hold up progress in the
OSM database for the sake of a particular GPS vendor or piece of software
not supporting the OSM data model. Right now with a point and area data
consumers would need to try to automatically remove points where they are
the same as an area they fall in. We shouldn't need to do that process. If
Garmin GPS's only support points, the conversion software should convert
these areas to points.

@Warin I support this, and would like to do this for the victorian airports
too.
