Oh I really didn't knew that those values are swapped. Generally it would be lat\lng. Sorry for that. That was a sample data I got from the team and yes that is Oz data(NSW boundary).
Anyway, to make it simple. I have created a project including the library: http://apache-flex-users.2333346.n4.nabble.com/file/n11744/StaticMap.zip It has data which is a rectangular region surrounding London. We can get lat\lng points of custom regions here(by drawing circles\rectangles\lines on the map): http://geojson.io/ In attached code, UK map gets plotted, only thing now is to draw\highlight region on top of the map based on the lat\long data.
