[Proj] Altering the +south paramter using UTM

Hi Frank/Others .
Hopefully this is a quick question but I am in the process of trying to
formulate the right parameters to transform data held in a modified UTM Zone
50 projection (epsg 28350) to GDA94 (epsg4283)
The only modification is to the false northing, so instead of 10,000,000
which I assume is the default value for +south, this data is stored with
16,000,000. I have been trying the following but no matter what I try I
don't seem to be able to modify the default value using +south= or +y_0=. Is
there a dependency to specify any other parameters with it?
cs2cs +proj=utm +zone=50 +y_0=16000000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0
+units=m +to +proj=longlat +ellps=GRS80
Does not work, simply ignores the false northing.
Thanks in advance for any advice
