Show country on order page

I would like to show on the order page next to the IP address the country that the order was placed from.

What is needed to get an IP to Country Name conversion that I can put on the Order page.

I am trying to prevent fraudulent orders that are from countries
such as Ghana, etc.

I only deliver to australia but I accept orders from many countries including the UK and US for delivery to Australia.

The frauds often only use Australian address so I would like to have a quick visual check of the country of the orders origin

Any pointers to the relevant functions would be appreciated

Further to this...
I am using the User Tracking mod from the downloads already
This has the Geoip data already installed.
I was hoping to use an existing function in this mod to display the country from the IP address on the order detail page in the admin.
All suggestions appreciated
