Welcome to the Q&A Forum

You should funnel all of your users through the main site and give them the option to switch languages to help avoid having the same content on different pages. It sounds like they want to rank in each country, now to do that, just build links and get them from relevant sites in that country. Although if you are really stuck on staying with the original plan, I would say use the robots.txt file to still block the other language pages. The reason I say that is because the search engines have done filtering to additional language pages, because spammers have actually exploited language barriers in the past for autoblogging. They would translate content from another language, make it sound right and then put it on the blog automatically. That's the main reason for me recommending that you funnel people through the main site and have them translate, which where the translation site would be in a subfolder blocked with the robots.txt file. There are obviously many ways to go about this, some will agree, so won't, this is just my two cents. I hope this helps.

Use words like: Kangaroo, Fosters, Wallaby, Shrimps, Barbie, Castlemaine XXXX, Strewth? Ah, the double English problem (rising to the triple and quadruple when thinking about USA and Canada). I can give you a few things but I've not had enough success with any to say they are undoubtedly the way forward. Another site a) Subfolder - /aus/ b) Subdomain - aus.domain c) New TLD - domain.com.aus Rather than hash out the pros and cons here's a recent Whiteboard Friday - http://www.seomoz.org/blog/international-seo-where-to-host-and-how-to-target-whiteboard-friday Also check the comments for some good suggestions and sites.
