Luke,

The first thing to verify is that your data was actually decoded by dcuair. If
your data does not have the product delimeters, chances are, the decoder said 
[DC 2]  Number of bulletins read and processed: 0
Make sure you are actually decoding data. If not, wrap your products with
FOS or AFOS product delimeters, such as is shown here:
http://www.unidata.ucar.edu/support/help/MailArchives/gempak/msg03796.html

Next, I'm assuming that your stations.tbl file has the id, latlon etc for your
station you are decoding. Since your data is in TTAA format, the 5 digit WMO 
number 
is part part of the product. You can specify this in your snprof AREA as:
AREA = @#####
or globally,
AREA=dset

Using the WMO number will work even if the station wasn't found in your station 
table to
define the country AU. You can verify what data is in your decoded data file 
using
SNLIST, specify AREA=dset, dattim=060121/0000 and SNPARM=dset, levels=all.
If your file has data for that time, you will see the station listed.
