Summer holidaymakers driving through NSW have been given a bum steer by Google Maps, which seems to think most of the Pacific Highway is closed.

Users have also reported being diverted through Wagga Wagga when travelling from Sydney to Melbourne.

Google's strange route from Sydney to Byron Bay.

Google Maps is the basis for several GPS devices such as Google Android and Apple iPhone smartphones, but those using it for driving directions up and down the NSW coast have had a puzzling journey.

For instance, those seeking driving directions from Sydney to Byron Bay are not given the option of going via the Pacific Highway and are instead told to travel inland through Gloucester, Armidale, Glen Innes and Tenterfield before arriving at their destination.
