Except for one day flying from Australia to New Zealand I haven’t seen a plane high in the sky since early December. No commercial flights flyover Tasmania – where would they be going? Same with South Island – there is just no where to fly to. Neither of these places are on the path to someplace else unless it is Antartica. It is actually noticeable after awhile. And the silence is spectacular, – deep and encompassing. No way to give the experience of silence through online media.
