The zones are at the food court, the rear entrance off Grose Avenue, the Albany Highway main entrance and the entrance near Coles off Albany Highway.
South Metropolitan Health Unit promotion officer Lisa Rooke said colourful signs had been installed and green lines painted on the ground to identify the zones.
�Shoppers told us they had been exposed to smoke around the centre and many were concerned,� Ms Rooke said.
�Most smokers want to do the right thing and they try to smoke where they won�t affect other people, but without clear direction and guidelines, it�s hard for them to know where to smoke.�
The initiative was implemented in partnership with the City of Canning.
Curtin University�s Professor of Health Policy Mike Daube welcomed the move, with smoking the largest preventable cause of death.
�Cigarettes cause the deaths of between a half and two-thirds of all regular smokers,� he said.
�The main diseases caused by smoking are lung and other cancers (including mouth, nose, throat, oesophagus, pancreas, kidney, liver, bladder, bowel, ovary, cervix, bone marrow, and stomach), heart disease and respiratory diseases but many, many other conditions as well.�
The Australian Council on Smoking and Health president said passive smoking caused about 600,000 deaths each year around the world.
�Passive smokers are at increased risk of lung and other cancers, heart disease and respiratory disease,� Prof Daube said.
�People with respiratory conditions such as asthma are especially affected, and children are particularly vulnerable to the harms of passive smoking.�
He said although smoking was declining in Australia, there was still a lot of work to do.
