Magento redirection with htaccess - .htaccess

Question

I want to redirect example.com to example.au,but at the same time i want to exclude example.com/admin from redirection. Is it possible if yes please provide any rewrite rules.Any help would be appreciated.
Code:
RewriteEngine on
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_URI} !^/(media|skin|js)/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} !^/admin [NC]
RewriteCond %{HTTP_HOST} ^www.example.com$ [NC]
#RewriteRule .* index.php [L]
RewriteRule ^(.*)$ www.example.com.au/$1 [R=301,L]
RewriteRule !^(admin/.*)$ www.example.com.au/$1 [R=301,L]

You can use following .htaccess redirection code for access admin
GeoIPEnable On
ReWriteEngine On
RewriteCond %{ENV:GEOIP_COUNTRY_CODE} IN$ //IN is the country code where you want to redirect
RewriteCond %{REQUEST_URI} !^/(media|skin|js)/
RewriteCond %{REQUEST_URI} !admin
RewriteCond %{REQUEST_URI} !index.php [NC] //admin keywords
RewriteRule ^ http://www.domain.in [R=301,L] //redirection url
In the above example admin and index.php are the keywords for accessing admin
RewriteCond %{REQUEST_URI} !admin
RewriteCond %{REQUEST_URI} !index.php [NC]
It means redirect to specific url in INDIA,only when the current url doesn't have the above keywords(all admin modules only have these keywords).
It would be help you. I'm also using the above same code for my store
All the best
