In Australia the weather is too hot in Christmas for Santa who might deliver gifts there?

Santa Claus lives in the North Pole, where the weather is always cold. Christmas in Australia is in the middle of summer, so the weather is very hot. If Santa were to deliver gifts to Australia, he would have to do so in a very different way than he does in other parts of the world. Perhaps he would have to use a helicopter or a boat, or even fly through the air on his sleigh powered by reindeer that can fly in the hot weather.
