The others are right, you'd need to go through your state's international adoption group, no avoiding the red tape. Partly, as Leash says it's to protect people being taken advantage of and giving up their kids without really wanting to, and they like to try to place a child with their own culture if they can. And then, you'd probably find kids from disasters finding homes in countries with slightly less red tape, like the US.
I hate how difficult it is in Australia, I totally get not wanting to take advantage but I think there must be a better system than what we have...
