Have solved this problem by using for example MGA94-56 instead of 
EPSG:28356 - which appears to be the same coordinate system just 
grouped within AUSNZ instead of EPSG

What you suggested below is exactly what i wanted to do, however 
replacing the coordinate system code with other text content without 
a coordinate system definition means that at the line 

IGDS_IN_COORDINATE_SYSTEM $(_IN_COORDSYS)

the coordinate system is not understood.  So what i was thinking was 
that i would need define descriptive text by assigning it to the 
coordinate system code but was not sure how to do it

ie OtherTextContent1 == EPSG:28356
   OtherTextContent2 == EPSG:28355

   GUI CHOICE _IN_COORDSYS OtherTextContent1%OtherTextContent2 Input 
Coordinate System:

   IGDS_IN_COORDINATE_SYSTEM $(_IN_COORDSYS)

Or have i answered my own question here?  Is == used for assignment?
