Post office boxes

Post office boxes are available in different sizes to suit the volume of your mail.

  • A small box, 90mm x 130mm, is ideal for personal mail.
  • A medium box, 135mm x 130mm, usually suits most small to medium businesses.
  • A large box, 275mm x 130mm, is designed for medium to large businesses.
  • Jumbo and A4 boxes are offered at some Australia Post retail outlets.

If you'd like advice on the post office box size that will work best for you, ask at any Australia Post retail outlet or call 13 POST (13 7678).
