Reach potential customers through letterbox advertising

Reach consumers and businesses more effectively by using Australia Post's Unaddressed Mail to distribute your letterbox advertising. Send catalogues, flyers and other promotional material nationwide, or target suburbs or postcodes.


Australia Post can give you access to up to 11.6 million letterboxes for community notices1 or up to 8.8 million letterboxes for other advertising1, including the advantages of:

  • metropolitan, regional and rural addresses
  • secure apartment blocks and high rise buildings
  • Post Office Boxes1


Items are delivered with regular addressed mail, so your catalogues and flyers are more likely to be viewed and read. In fact, 83% of people take the catalogues, flyers and brochures they receive with normal addressed mail into the house.2


You can trust Australia Post to deliver your letterbox advertising as specified. You can also rely on accurate address counts for your nominated delivery area. Our address data is based on fact, not assumptions, and is updated regularly to ensure it's up to date. This helps you to reduce advertising wastage by printing only the quantities you need.
