Wanneroo – WA 2021

ALP 8.9%

Incumbent MP
Sabine Winton, since 2017.

Outer north of Perth. Wanneroo covers the suburbs of Carramar, Tapping, Ashby, Sinagra, Wanneroo, Banksia Grove, Mariginiup, Jandabup and Gnangara, in the centre of the Wanneroo council area, as well as less-populated areas further to the north.

Wanneroo’s southern boundaries were changed, losing Hocking and Pearsall to Landsdale and gained Mariginiup, Jandabup, Banksia Grove and Gnangara from West Swan. These changes increased the Labor margin from 7.3% to 8.9%.

Wanneroo was first created in 1989, and has gone to the party of government at every election since 1993.

In 1989, the seat of Joondalup was abolished and replaced by Wanneroo. Sitting Joondalup Labor MP Jackie Watkins moved to Wanneroo.

Liberal candidate Wayde Smith defeated Watkins in 1993. In 1996 he was denied preselection in 1996 and succeeded by fellow Liberal Iain MacLean.

MacLean lost the seat in 2001 to the ALP’s Dianne Guise.

Guise became the first Wanneroo MP to win a second term in 2005, before losing in 2008 to Liberal candidate Paul Miles. Miles was re-elected in 2013.

Miles was defeated in 2017 by Labor’s Sabine Winton.


Wanneroo has a history of flipping back and forth. If the Liberal Party is on track to win the election they would probably be competitive here.
