Hey Frank
after lots of searching online, i have found and added an extra piece of code to backend file.
On file manager (cpanel) go to plugin folder
public_html/wp-content/plugins/autocomplete-location-field-contact-form-7/includes
open or edit php file GWAA_Backend.php
add extra code after autocomplete.inputId = acInputs[i].id;
extra code:
// Set initial restriction to the greater list of countries.
// [START maps_places_autocomplete_countries_multiple]
autocomplete.setComponentRestrictions({country: [“au”],});
you can select your country based on google country codes.
it worked for my site.
