There used to be an enclave of State-provided housing in the area north of Denman Ave, in the Yathong Rd, Cawarra Rd and Taronga Pde vicinity, adjoining the light industrial area further to the north. That was quite a while ago though. Not sure how much that has changed.
In North Caringbah itself, no there isn't a lot of housing commission. In Caringbah CBD there is. 2 completely different areas.
