I am not sure if I understand what exactly you are trying to achieve, 
you are not really providing all the information to understand the 
problem fully.
But between the lines I read your BO has 2 NICs, one connected to the 
public internet and one connected to an internal (RFC1918 style) intranet.
Your internal DNS points the hostnames in question to the IP of the NIC 
which is connected to the internal intranet, your external DNS hands out 
the IP of the external interface. Am I right so far ?
Now I think you expect to access i.e. remote.otherdomain.com.au through 
internal as well as external network interface.

If I am still right, the answer would be: Won't work out of the box, 
every site is bound to a single IP and therefor to a network interface. 
The thing you believe is working, is probably just site1, which is shown 
if no virtual host directive matches, as the site1 is the default server 
for everything unmatchable.

You could however copy the contents of /etc/httpd/conf/vhosts/site1 to 
the end of /etc/httpd/conf/vhosts/site1.include and just change the ip 
address in the NameVirtualHost Directive there to the second IP-address. 
I haven't tested this, but I think this should work.

hth,
