You can promote reconciliation with Australia’s First Nations every time you send or invite mail.

Including Traditional Place names
To acknowledge the Traditional Custodians of the land your item is being delivered on, you can include those place names in the address field.
To find Traditional Place names, check AIATSIS, Aboriginal and Torres Strait Islander Land Councils, or Cultural Centres in your local area.
When sending items you can include a Traditional Place name in either the address you’re sending from, or in the recipient’s address.
At Australia Post, we have a long and proud history of promoting and celebrating Aboriginal and Torres Strait Islander Culture and implementing measures that contribute to a lasting reconciliation between Indigenous and non-Indigenous Australians.
To make sure the item will be delivered correctly we recommend that the Traditional Place name is included below the recipient’s name but above the street address.
