I'm off to Australia on Wednesday and just wondered if anyone knows if SMA Gold formula powder is sold there? It would be great not to have cart too much of the stuff in our luggage. Other questions - I have been told conflicting viewpoints on whether you should or shouldn't break the seal of the formula tin when putting it in the hold? And also is there a limit to how much formula you can take into the country? If anyone can advise that would be fantastic. Thank you.
