Gosnells, which is proposed to be renamed Coombs, will gain parts of Maddington south of Maddington Road and the Kenwick Link, Kenwick south of the Kenwick Link, and Martin west of the Tonkin Highway.
With the gains comes the loss of Gosnells south of Corfield Street and east of Verna Street.
Southern River will also undergo a change in electoral boundaries as it will gain Gosnells south of Corfield Street and east of Verna Street, but will cede Canning Vale south of Ranford Road and west of Nicholson Road.
The reasons for the change in the Gosnells boundary is to accommodate a reduction in elector numbers in Darling Range.
It was not possible for Southern River to keep all of Canning Val due to urban population growth, so Nicholson and Ranford roads were chosen as boundaries.
Gosnells has been proposed to be renamed Coombs after HG �Nugget� Coombs, who was an Australian economist and senior Commonwealth public servant educated at the Perth Modern School and the University of Western Australia.
He went on to become Director General of the Department of Post-war Reconstruction and later Governor of the Reserve Bank.
