A few comments
- I found the (black) text difficult to read on my machine. (may be it's due to my settings, but it may happen on other machines too)
- You should perhaps put a link on each domain (in addition to the message 'purchase any of these domain names for your business or for investment')
- the pink big logos on left give the impression they are banners. It does not give a positive impression for the site.
- I also wonder if it's a good idea to use the com.au extension to sell domains that are not specific to the australian market.
Sorry to be somehow negative but I'm trying to be constructive. I think you should have a look to BB or brandroot.
