I used NHA20, NHA1 and NHA16 to all refer to the Shields with
'National' on across the top to correlate with the remaing 'National'
Routes being labelled NH20 in the rest of the country. I can tell you
that apart from the Issue of whether NH is approriate for those signs
(N could also be I guess). The area around Gepps Cross is completely
accurate with the signging in the area. The roads maked 'NHxx' all have
'National' Across the top of the shield in those areas. NSW has chosen
to remove all Nationals from what I see online, but SA so far seems to
be keeping them and even new signage is still getting "National".

Hope that makes things a little less murky for you.
