House of Assembly Fifty-Fifth Parliament, First Session (55-1) 55 1 Parliament of South Australia House of Assembly published Estimates Replies Optus Data Breach Optus Data Breach The Hon. V.A. TARZIA House of Assembly Hartley Optus Data Breach In reply to the Hon. V.A. TARZIA (Hartley) (30 June 2023). (Estimates Committee A) The Hon. A. KOUTSANTONIS House of Assembly West Torrens Minister for Infrastructure and Transport Minister for Energy and Mining Optus Data Breach The Hon. A. KOUTSANTONIS (West Torrens—Minister for Infrastructure and Transport, Minister for Energy and Mining): The Department for Infrastructure and Transport advises as a result of the Optus data breach an estimated 125,051 customers had their driver's licence number changed. The Malinauskas government assisted South Australians affected by the Optus data breach through the waiving of the standard $20 licence replacement fee to affected South Australian customers. At the time, we announced our intention to seek reimbursement from Optus of any taxpayer liability. In December 2022, we advised that our negotiations with Optus were successful, with Optus providing reimbursements for the cost of replacing affected licence cards and associated expenses. This outcome could not have been achieved without the outstanding work of Service SA workers across the state. Their tireless efforts helped South Australians regain security of their identity. This reimbursement by Optus, coupled with Service SA raising the bar when it comes to public service, is an excellent outcome to an unfortunate event.
