Routed OFF is the correct configuration.

However problem b) is a DNS problem:

gdi,ttyp1,~,18>host smmc.qld.edu.au
smmc.qld.edu.au has address 203.56.180.1
smmc.qld.edu.au mail is handled (pri=10) by smmcroute.smmc.qld.edu.au
gdi,ttyp1,~,20>host smmcroute.smmc.qld.edu.au
smmcroute.smmc.qld.edu.au has address 203.56.180.1

Notice that smmc.qld.edu.au == smmcroute.smmc.qld.edu.au.  

Your MX record points back to the same machine, creating a mail loop. 
Sendmail is doing you a favor telling you about the misconfig.  I suggest
removing your MX entry or point it to a different machine.
