christmas is a big occasion here too, we all take turns having it and everyone brings a plate of whatever they specialise in.
generally we have

cold roast chook and ham
hot roast pork and crackling
aberdeen sausage
fresh aussie tiger prawns
past salad and coleslaw
cous cous salad
pear, bacon and fetta rocket salad
caeser salad
apple, cranberry, seafood and tartare sauce plus gravy
a frozen xmas pudding thingy (not sure what the actual name is but usually when i say a frozen pudding thingy people go oh yeah they are yum)
summer fruit trifle
cheese cake (flavour varies)
pavlova
fruit salad
various ice cream flavours
various slices depending on whos making them
all the trimmings - toppings, cream, liquer sauces that sort of thing

all the nibblies like rum balls, peppermint balls, white xmas, xmas shaped chocolates, white choc truffles (i make and they are to die for), cheeses, dips, biscuits etc etc
fruit punches both alcoholic and non alcoholic as well as the general bevvys like beer, wine and cordial

It actually isnt a lot as each person brings an appropriate amount of their thing and any left overs are divvied up between us all.

i like the sound of choc ripple cake and am off to google it. also turducken best google that too, might have some new things for the menu
