Up to 20 per cent of kids in Queensland Indigenous communities do not have birth certificates.

To correct this, the Queensland Government is setting up pop-up offices staffed by workers from the Department of Births, Deaths and Marriages.

“It would appear that awareness is a big thing and the value in registering a birth,” Queensland registrar-general David John says.

“The more remote the citizen lives, the less likely they are to have the full suite of identity documents required to prove one's identity.

“The main issue they face [without a birth certificate] is trying to get a tax file number or a licence or a passport.”

The Queensland Ombudsman had previously labelled efforts to address the identity problem as inefficient and discriminatory.

The mobile office has been visiting Thursday Island, off far north Queensland, but has plans to continue visiting remote Indigenous communities over coming months.
