Content Duplication and Location Targeting

I have separate service pages for Melbourne and Brisbane with unique content, but the services are the same. Can Google penalize me for this duplicate content, even though the content is targeted to different locations?

as long as the content is unique you're good to go! Offering the same service(s) in multiple locations is the nature of businesses, if google penalized you for this they'd have to penalize every single business under the Sun that offers the same service in multiple locations. It's all good

Nope they won't
