VVV I'm well acquainted with the Menangle /Camden region, in fact most of Sydney's outskirts. Suburbia is spreading on all of Sydneys outskirts and there is a population increase of 200,000 planned for the southwest. However Menangle was earmarked for development some years ago but this was put on hold due to the coal resources underneath it and the developers moved to the north and northwest of Camden instead-Oran Park, Gregory Hills etc. It will be quite sometime before there is further development in Menangle if at all. If Sydneys second airport goes to Wilton (I doubt very very much it will go to Badgeries Creek) then all the southwest development will need to be rethought.

Given that Menangle Park is adjacent the river and flood affected I'd have doubts about its future worth for development.

Heres an excercise for you VVV try taking public transport from your place to Menangle and back and see how you go? Would you let your kids do it?
