CSIRO is an Australian government research agency with a long history.
Siromath, a commercial spinoff, had a binary redistribution license
for Unix.  The Siromath Unix was called SIRONIX.

The Australian Unison computer was sold with SIRONIX.

Siromath was also going to provide a version of Unix for
the DCR/CSIRONET workstation.  At some point they switched to
a port of System V/68 from Neology/Softway.  Does anyone know why?
Or if the CSIRONET workstation got beyond the prototype stage?  Did
it get cancelled when CSIRONET was privatised?
