The Best Way to Eliminate Stomach Flab

I am looking for the best way to eliminate stomach flab. My weight is not really all that big of an issue to me, although I suppose that I am around five pounds heavier than I probably should be and it all seems to be in my midsection. I am either sitting on it or it is in my belly. i want to get a flat stomach fast, because I have a huge trip planned for the winter. I am going to spend a whole six months living in Sydney Australia with my grandfather.
