Help with SEO recommendation re duplicate home page content

Hi, my client has had an SEO expert provide them with a document outlining the improvements that can be made to their site to improve SEO. One of the most important items is re Duplicate Home Page content. They have asked that I:

1. Perform a 301 re-direct from http://www.website.com.au/index.aspx to http://www.website.com.au

Was told by BC that it's not possible to do a redirect to or from an aspx page and it's not indexed in the sitemap anyway. Will take their word for it on that.

2. Perform a 301 re-direct from http://www.website.com.au/home-page to http://www.website.com.au

Was told by BC that since /home-page is set as the start page, then it can't be re-directed to itself. This is also where they said to consult the forums for a javascript or some other workaround for this?

Can anyone please assist me with this one?

Thanks in advance.
