Mitchell is a largely white collar, upper class and socially conservative electorate in the Hills district of northwestern Sydney.
The majority of the electorate is fairly conservative, and it has been a safe seat for the Liberal Party of Australia for most of its existence.
However, the southernmost suburbs of North Rocks, Northmead and Winston Hills are located in the Parramatta local government area, and share that LGA's bellwether tendencies.
After the 2013 federal election, Mitchell replaced nearby Bradfield as the safest Coalition seat in metropolitan Australia, with Labor needing a 22-point swing to win it.
[4] As of the 2019 federal election, it is the second-safest metropolitan Coalition seat, behind Cook, with an 18.6-point swing needed for Labor to win it.
