Get your letter right and ready

Letters sent within Australia can only contain flexible items no thicker than 5mm for small letters and no thicker than 20mm for large letters. If your letter is larger than our maximum size and weight, or contains rigid or inflexible material, it will be considered a parcel. 

Letters sent overseas can only contain printed material with no commercial value. If your letter is larger than our maximum size and weight, it will be considered a parcel and require a customs form
