In Australia, many people put up their Christmas tree on the 1st day of December. It varies. There is no tradition in Australia for when to put up the Christmas tree. Some people put it up early in December, while others put it up at various times in the weeks preceding Christmas. Some may leave it until Christmas Eve. There is truly no tradition.

It really isn't too early too put up the Xmas tree for it all depends on if you have the Christmas spirit. In 2 weeks is the first day of advent which is when some people put their Christmas tree up so it is perfectly ok to do so.
