Is there an easy solution for duplicate page content on a drupal CMS?

[ClintonP]

I have a drupal 7 site www.australiacounselling.com.au that has over 5000 crawl errors (!).

The main problem - close to 3000 errors- is I have duplicate page content.

When I create a page I can create a URL alias for the page that is SEO friendly, however every time I do this, it is registering there are 2 pages with the same content.

Is there a module that you're aware of that I can have installed that would allow me to show what is the canonical page?

My developers seemed stumped and have given up trying to find a solution, but I'm not convinced that it should be that hard.

Any ideas from those familiar with drupal 7 would be greatly appreciated!
