 :Thanks, I started in late Jan after you created the stub. I liked my lead image and really wanted a longer article to go with it. As for GA I still have a few things I want to sort out (finish the top-down map, make the profile map showing the construction of the fort. Fixup ref45 which is missing information, some mos issues etc.) though some of these (the maps) are not required for GA. Not really a wiki collaboration for this though WP:Adelaide and WP:Australian History do cover this one. Someday I'd love to work with you on Marble Hill - if only I could find enough good written sources ! Local history and conservation parks are hard to source outside of sketchy web links and government management plans -    ::Re:Marble Hill, I've been to the SLSA and found quite a few good articles in the microfiche newspapers (one from the opening in December 1879 is particularly informative - describing the parliamentarian's reactions and outbursts as well as the building and the drive up). I'm also reading Lady Tennyson's diaries, which are a fascinating insight into life at MH (they would only be borderline RS though - self published). A good proportion of the information since 1955 is unfortunately in primary sources and therefore OR (though there are a few self published booklets or webpages).
