You may need to attribute more specifically, eg

attribution=Based on Bureau of Meteorology, Australia

I'm not sure what they specifically asked for, in some cases you also
need to specifically attribute a URL

Is this a new site, or does it no longer operate?

I thought about including stations that no longer operate and use an
end_date=* tag but eventually decided against it because some of these
ended up in the middle of what is now the gateway motorway.

I think NOAA only lists weather stations that measure temperature,
many post offices only measure rainfall, so they would be missing for
that reason, you might want to add a note indicating that these need
to be checked for what they actually measure.

You could have used a bbox to exclude areas outside of Australia, eg:

http://xapi.openstreetmap.org/api/0.6/*%5Bman_made=monitoring_station%5D%5Bbbox=110,-45,155,-10%5D

The co-ords above only include the area approximately covering the
Australian mainland and Tasmania, if you want external territories
such as Christmas Island and Norfolk Island, you'll need to extend it
a bit further.
