I didn’t hazard a guess before clicking your link, but to quote a believer in your video, “Don’t take my word for it. I could be a mental patient recently released from an institution”.
We party hard, lot's of great food, lot's of ***, hangovers to follow.
We dress kangaroos as reindeer's, roast the odd possum or two, shove Santa into the tray of a FJ holden ute, then see if we can dump him out driving flat out over a Mulga stump.
Good thing Oz is the last country Santa visits, he goes home hungover with a smile on his face but takes a year to recuperate.
There are lot of "northern hemisphere" Christmas cards available here.
There are a lot of "Aussie themed" ones too.
Yes Christmas trees are the norm.
I guess the only difference deep down maybe what we eat on the day.
Hot meals are dropping out of favour, lot's of cold cuts, seafood and salads seem to be the "in thing" these days.
