well this was crazy.
I've been thinking about doing a map of kyeemah for a while... from sattelite it looks like a fairly unique area... furthest east is the beach and parks, theres a bike trail around some urban areas... there are some market gardens, some wetlands, some overpasses/underpasses, and playing fields.... but i'd never actually seen any of it!
turns out its kinda a web of trails through wierd overgrown shrubbery, with pockets of supposed homeless people's spots etc. The playing fields SEEM abandoned completely... and the only way i could find in was a hole in a rusty fence, the stadium is basically falling down, and theres this huge area of wetland basically under the motorway.
I didn't actually jump through any fences or see any signs anywhere, but i'm still not completely sure i'm actually allowed to be anywhere on the run, despite there being little trails and big vechicle tracks... perhaps the playing fields are in the process of being taken over by a concrete business there...
Anyway i'll do a rough map of the area, and definately go back... it's so unique, but a little scary thinking about the kind of people and/or things you could find down some of the dodgier bits...
Some research says it's called "Barton park" and theres a group trying to "saveBartonPark.com". some details here

[EDIT] Glenn has suggested its earmarked for westconnex / freeway work which might make some sense.
