I am using Google maps and I want to restrict user search results to only Australia. For example, if user enters 'Melbourne', currently it is redirecting to Melbourne location in US. Also, the zip code 3000 is redirecting to some country in Europe.
How can we restrict these kind of issues? What are the options that should be enabled in the Google maps.
Note: I am not using any API key for this. Can we restrict people to Australia if we have an API key?
