Spoiler alert: the country that requests the most data from tech companies is not Australia. It's the US. Although we are number nine overall on the list and we did request a boatload of stuff from Twitter.
Australia is ninth overall, requesting the most data from Twitter and Microsoft.
Looking at the graph, it's feasible to think that the United Kingdom and France might be just as horrible as the US since they have nearly half the requests with a significantly smaller population. Though of course the US has PRISM.
Reuters cooked up this graphic by culling all the data from Google's 2012 Transparency Report, Microsoft and Skype's 2012 Law Enforcement Requests Report and Twitter's Transparency Report. You can see in the graphic how most of the requests were disclosed. [Reuters Tumblr]
