You have set the MAILMAN_USER and MAILMAN_GROUP macros to 'mailman'.
The suggested mailman transport for exim contains


which tells Exim to run the pipe to the wrapper as user:group =
mailman:mailman. If Exim has sufficient privilege do do so, it will.

I refrained from referring you to the FAQ at
<http://wiki.list.org/x/OIDD> in my initial reply because it appeared
you were installing Mailman from source, however, as others have
pointed out, the document at
<http://www.exim.org/howto/mailman21.html> is written from the point
of view of a "normal" Exim configuration where everything is in one
large file. You are apparently trying to install Mailman in a "hybrid"
manner where you have installed Mailman from source, but are still
using the (Debian/Ubuntu ?) Exim/Mailman packaging. Thus, the FAQ at
<http://wiki.list.org/x/OIDD> is applicable.

Everything in section 6.2 of the install manual is Exim configuration.
Nothing goes in mm_cfg.py and Defaults.py should never be changed for
reasons discussed in the FAQ at <http://wiki.list.org/x/fIA9>.

If you had a standard Exim config, thos would go (actually, the first
would probably alreade be) in the ACL CONFIGURATION section of
exim.conf under acl_check_rcpt:. I have no idea into which sub-file
your configuration has split that off.

This indicates a syntax error somewhere in the acl_check_rcpt: section
of your exim configuration. What did you change there?

These all say that Exim has temporarily rejected outgoing mail from
Mailman because of the initial error.

What does

 exim -f mailman-bounces+info=mymaps.gov.au at mymaps.gov.au \
 -bt info at mymaps.gov.au

or perhaps

 exim -d -f mailman-bounces+info=mymaps.gov.au at mymaps.gov.au \
 -bt info at mymaps.gov.au

tell you?
