This area stretches from Singleton in the south to Two Rocks in the north and east to The Lakes.

The MRS defines the future use of land, dividing it into broad zones and reservations. It requires local government town planning schemes to provide detailed plans for their part of the region. These schemes must be consistent with the MRS.

The MRS uses a set of maps and a scheme text. The scheme text provides planning rules for zones and reservations which are shown on the maps in different colours and patterns. Refer to the Metropolitan Region Scheme - Scheme text which is amended from time to time.

This plan has been in operation since 1963 and provides the legal basis for planning in the Perth metropolitan region. To plan for changing needs, the Metropolitan Region Scheme map is amended frequently.
