Hi Doug,

You can achieve it by using the acf/save_post hook and the update_field() function like this:

function my_acf_default_map( $post_id ) {
    
    $selector = 'google_map_field_name';
    // get new value
    $value = get_field($selector, $post_id);
    
    if( !$value ){
        $value = array(
            "address" => "218 Abeckett St, Melbourne VIC 3000, Australia",
            "lat" => "-37.81025862543725",
            "lng" => "144.95670318603516"
        );
        
        update_field($selector, $value, $post_id);
    }
    
}

// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_default_map', 20);

But if you only need the address, which is basically a text, then you can always use the text field and set the default value on the backend instead.

I hope this helps 🙂
