That's cool. No one else had made a suggestion, and
Christmas Child is one I've helped out with a few times before. I see you're point about helping our backyard, but from a global perspective our backyard has it easier than many billions of people living internationally. Not to say that it's easy, but that other people have it harder, and would also appreciate some help.
There will always be needs in our own backyard, and if we focus just on them, then there are many more people who will not recieve any help at all, simply because they were not fortunate enough to be born in Australia.
Just my own thoughts on the subject.
