[SLUG] multiple domain to one web site

["Voytek Eymont" <lists@xxxxxxxxxx>]

when setting a single web site with multiple domain names, like, name.com,
name.com.au, name.net.au, is there any recommended way to run that, from
search engine perspective ?

I normally set 'alias' directive for each additional domain in Apache
vhost conf, just curious if that the way, or is there a more appropriate
setup ?
