In Aus we don’t have Thanksgiving.
Some people start at Advent, others who might not be Catholic, start of December until midway in December. There is a community competition for the best decorated houses externally, people have started their decorations for that now, and the councils have put up their Christmas decorations.
Personally living with working dogs myself and family don’t do inside decorations. Its too much of a challenge for them. The kids are doing external decorations though, on their house.
I might decorate a few gum trees out on the farm.
I have a goal to display a nativity scene . Our parish will put the Jesse tree up this coming week and each year there is a display of nativity scenes from around the world. Thats pretty awesome.
We have extra adoration during advent, run by one of the Priests, and the Cathedral organ gets a work out for all the groups who run carols.
