How to access attribute from object in Laravel

I am using Elasticsearch to get data.

$addresses = Address::multiMatchSearch()
    ->fields(['full_address'])
    ->query("nsw")
    ->fuzziness('AUTO')
    ->paginate();

foreach ($addresses as $address) {
    dd($address);
}

I am receiving the object in the following format. How can access city attribute from object ? As you can see that I dd inside a loop. This will be the first record.
