At the end of Gosford street, there's Gawler creek and old unused train bridge. There paths down though the area, if you follow them in direction of old track. You will find paths and a footbridge, that crosses the creek. Cross the bridge, follow the path you see a bench and the path runs along the old track. There is a lot of closed off bushes and sections along the old train bridge and tracks. Either at top of train track or bench next to path are good places to meet.
