How to stop Google going to the country-specific site (google.com.au instead of google.com)

  Sometimes you may wish to search Google without being redirected to your local country’s version, as you are likely to get different search results based on your location.   Try the following URL:  
http://www.google.com/ncr
  NCR here is no-country-redirect, and Google will leave you at simply google.com rather than google.com.au for Australians.
