How to find historic Facebook fanpage figures for \australianaid

While gathering the latest figures on the growth of Facebook fanpages in International Cooperation, I discovered that I missed a major player alltogether. It seems that Australianaid published it’s first Facebook post in November 2011 (here). So I had wonderful growth lines in Excel, but Australians have been missing. After asking a PR rep on LinkedIn for help, I’m still waiting for an answer. But I came up with a solution to have at least a few milestones from this year, thanks to the Google Cache.
