Western Australia's state-owned land title registry has been partly sold to a consortium comprising Macquarie Infrastructure and Real Assets, and superannuation funds Sunsuper and HESTA.

The consortium will take over Landgate’s automated titling services, including property transaction processing and title register searches, for $1.41 billion up-front plus ongoing revenue, WA Treasurer Ben Wyatt says.

The up-front funds will be used to pay for WA’s participation in the national redress scheme for survivors of institutional child sexual abuse and and the costs of lifting the state’s statute of limitations for historical sexual abuse.
