To the north, the electorate includes the developing township of Bullsbrook and the Avon Valley National Park.

To the south, the electorate captures the Swan Valley localities of Upper Swan, Baskerville, Brigadoon, Millendon, Herne Hill and Red Hill.
Swan Hills also includes a vast but sparsely populated area of the Perth Hills to the east, including the localities of Gidgegannup, Mount Helena, Chidlow, Wooroloo, Beechina, Bailup, The Lakes, Gorrie, Sawyers Valley and Malmalling.

The electorate includes portions of two Local Government Areas; the City of Swan and the Shire of Mundaring.

The local Federal Member of Parliament is Tania Lawrence - Member for Hasluck.
