In the Philippines, it's just pancit, karaoke, and lots and lots of food. That's it.

Well, I've only been to birthday parties, and there is essentially lots of food, and you beat an object made of paper mache to death, and it's internal organs are candy

Sounds fun

Oh and also, the best kind of parties in the Philippines are family reunions, cuz it's when your old relatives give you lots and lots of cash.

Chinese New Year?

One word
Beer

In Australia, there's just food, socializing, and games, usually made from home-made objects. They're really fun. Also, if you have a pool, everyone goes swimming.

Fireworks (if it's the 4th of July)
Red plastic cups
Music
Shit ton of food
Swimming (if it's summer)
Alcohol

And video games if your a child

lets not forget breaking public property, both intentional and unintentional

Oh yeah
I can't forget that

And the one year I got to use firecrackers

a bunch of drunks destroying everything

Only been to birthday parties

I assume you just invite a whole bunch a people then there

so um...
caca and a shitload of parent sugar
