The park between Falcon Cres and Argyle Courts has some impressive huge old trees. I'm thinking by your date the ground should be covered with leafs (it was when we did a shoot with our little guy on the 21st last year). Makes for a real nice fall scene as long as your photographer can work their magic with the lighting.
Only asterisk being be prepared to have someone stop by the night before or even that morning just in case a little cleanup is necessary. The park is bad for people leaving garbage, shopping carts, etc lying around.
