You can't put anything about company2.com.au in db.company1.  You need:

primary company2.com.au /etc/named.data/db.company2
primary company3.com.au /etc/named.data/db.company3

Where does your original requirement "using only one database file" come
from?  What is it you're really trying to accomplish?

If you want all the domains to be identical, you could do:

primary company2.com.au /etc/named.data/db.company1
primary company3.com.au /etc/named.data/db.company1
