Services Australia was forced to freeze nationwide printing of pensioner concession cards after a private contractor mistakenly released the personal data of more than a hundred people to the wrong households.

An agency spokesperson confirmed it halted physical card production in late May after it became aware of a "mailing error" by an outsourced contractor, after more than 140 people were sent incorrect cards containing strangers' personal details.
