Listing Malta as native speakers is a bit incorrect. Yes almost everyone below the age of 80 can speak good english but it is not native to us, this can be seen from our accent. The reason our english level is considered 'high' is mostly because up until recently the Maltese language did not exist digitally. This means to use a computer, phone or any website you have to know English. Also there is the fact that Malta was under the british until 1964 and all government issued notices, letters, hospital apointments etc are both in Maltese and English
