Several patches of Galium aparine scattered along the Hackett Houses track, Mt Majura. Very large thicket at entrance to reserve near 57 Mackenzie St which may be source of seed picked up by walkers entering the reserve.
Chris the weeds are also the result of garden waste dumping I'm afraid. FoMM removed a vast amount of plants from that area which were clearly the result of dumping; the weeds are spreading if not attended of course. It is too much for 1 (!) person to attend to all weeds that grow in the nature reserve. I work already up 10 hours weeding shifts per day if weather permits....
