That is pretty much what the plugin does. It writes all events to syslog 
which based on rules in /etc/rsyslog.conf decides what to do with the text. 
Typically it is to write everything to /var/log/messages.

However, you can assign a specific facility to the audit events in the /etc/
audisp/plugins.d/syslog.conf file and then in rsyslog.conf exclude the 
facility by putting <facility>.none on the /var/log/messages line.
