bing does geotargeting of domains, to the country the search is being done.
localised searches plays a big part with bing.
so if you searched for the same terms while you in australia, you will probably find you won’t be in the top 10. (i just checked bing from australia.. and you don’t appear in the top 10 for those terms here)
I’d still want to trade with you! More gambling searches in the UK then in Australia.
