Taking organic things is usually denied by customs (being in the U.S. the general policy is unless it's something refined you probably will be stopped by customs) things like live plants, natural stones (unless refined or in very small size/quantities), animals, soil, etc. Will not be allowed through customs. Honestly I would contact your airport to see what their policies are on customs for Australia and see if it would be an issue on your side or Japan's side for you to do something like that rather than asking the fish forum. I can say from my own experiences traveling out of country and back to the U.S. I've never tried something like that because it would be a hassle to get through customs. I deal with refined stones for my business for the reason that if I have to order something from outside the U.S. refined pieces are much easier to pass through customs.
Life without an aquarium is just flat out boring, Unfortunately like most in the hobby I'm highly susceptible to Multiple-Tank-itis.
