Does most of Australia celebrate Christmas?

Answer 1

Owing to the seasonal inversion caused by the southern hemispheric tilt- Santa Claus would have to make the rounds on a surfboard- as they have their Summer season in what to us are the Winter months. this seasonal inversion is caused by the axial tilt of the earth. ( if it was straight up 90 degrees it would not happen). Certainly this geographic fact complicates the Santa Claus mythology- so it is not , on credibility grounds, probably practiced.

Answer 2

Yes. Australia is a predominantly Christian nation, so most people celebrate Christmas. The only ones who don't are certain religious groups - similar to those that also exist in other nations. Even the indigenous people celebrate Christmas to some degree.

Answer 3

Yes, many of them do.
