Polystyrene waffle pods used in concrete slabs from nearby housing developments were swept up and dumped across private and public land during wild winds earlier this month.
Nicole Colquhoun has driven around the area for her job for the past two weeks and said large and small pieces of the pod blocks were still "everywhere".
She is calling on Wollongong City Council to allocate more resources to the clean up.
"There is still so much to clean up and nothing is being done," Ms Colquhoun said.
"Council really needs more crew members to pick it all up.
"The creeks and drains are full of polystyrene and there are ducks and other birds in it.
"Once it rains there will be nothing to stop the material going out to the ocean.
"One piece which is more than one metre squared is sitting up a tree.
"There are millions of small fragments up the entire verge area along West Dapto Road."
Ms Colquhoun fears the council is not willing to punish the building companies responsible for letting the debris be swept onto land.
She wants council to go the extra mile to find out which companies are at fault.
"No one is taking responsibility," Ms Colquhoun said.
"None of the builders have come forward to assist in the clean up.
"The NSW Environment Protection Authority is not interested in helping.
"A lot of the private land has been clean up but not the public area."
It's estimated council crews collected about 260 cubic metres or the equivalent of about 800 blocks of the material in one week.
Council crews, with the assistance of community service personnel, completed a two-week clean up in the area.
"The environmentally-damaging material was collected from both public and private land," a council spokeswoman said.
"For access onto private land, such as farms, council staff needed the permission of private landowners to enter.
"If community members see pieces of uncollected polystyrene, we ask they get in touch with council's customer service team so that, if the debris is on land we're permitted to enter then we can remove it.
"We're also pleased to say we've contacted the suppliers of these pods and who have agreed future deliveries of the pods will be secured on building sites with netting and pegs.
"Council is continuing to make appropriate enquiries to determine the source of the pollution and taking regulatory action where required.''
