Deliciousness
YUM We just had a plain fruitcake with white icing for christmas, none of this amazingness.
Re: Sunflower, we have much lighter meals (seafood, fruit and cake rather than mountains of meat) and don't even begin to do flower crowns - we just have paper hats instead. Superficial ideas like the tree, bonbons, Christmas lights and Christmas hams make it through, but all the symbolism (Christian and Pagan) is gone.
You have to remember that Australia has no (widely acknowledged) cultural history, and the Aboriginals didn't tie anything to the solstices. About 30% of us have no declared religion, and 10% of those may be atheistic. In that sort of environment it becomes very hard for any religious tradition to survive, much less the original beliefs stolen by missionaries and eventually sent halfway around the world to Australia.
