    Hi Nick, would we be better off following the others? It would take into account earth’s axis, rotation etc ?..

      Hi Klim. Thanks for your question, but the only thing that we need take into account is the Australian climate. A summer made up of December, January and February seems to match our climate as the hottest days in the year do tend to occur in the middle of the period. In addition, summer starting at the beginning of January is the local tradition and there is no reason to follow that of another country or continent.
