A woman and her six children have camped across from the West Australian parliament in protest of the family being denied public housing.

Robin Stratton said the family were forced to move out of their Wilson public housing property in November - and stay in tents in various friends' backyards - after their tenancy agreement came to an end.

"The Department of Housing simply didn't want to renew my tenancy after 30-odd years of being in a tenancy," she told 6PR radio on Wednesday.

"They just didn't give no reason. I know that I haven't been a model tenant. I've had my ups and downs.

"I was under the understanding we were doing alright. We were on a Strong Families program.
