A post on Google Australia's blog yesterday announced the launch of Google +1 in Australia. The social recommendation system has been available in the US since the end of March, but now Australian users will be able to mark their favourite Web sites.
According to the Google Australia blog the service will initially only be available to some users, but should be rolled out to any logged-in Google account in Australia by the end of the week. The main use for +1 will be on Google's organic search results, but Web sites are also able to integrate +1 buttons — the Google Australia blog says sites like Kogan and the Trading Post will have +1 buttons on their sites soon. The Kogan Web page for the Agora 12in Chromium OS-powered laptop already features a +1 button.
