The CTP Regulator (the Regulator) is an independent Statutory Authority established under the Compulsory Third Party Insurance Regulation Act 2016 (the CTPIR Act). The Regulator is responsible for regulating and monitoring the South Australian CTP Scheme (the Scheme). The functions of the Regulator are determined by legislation.

The Regulator’s responsibilities are to:

  • make, monitor and enforce the Regulator Rules to ensure CTP Insurers meet their legislative and contractual obligations (such as meeting claims management and dispute resolution standards)
  • determine premium amounts for CTP insurance policies
  • determine the minimum terms and conditions of CTP insurance policies
  • provide information to consumers about the Scheme and CTP Insurers
  • make recommendations to the Minister about:
    • eligibility criteria and assessment of applications for insurers to become a Government-approved CTP Insurer (or withdrawal of an approval) under Part 4 of the Motor Vehicles Act 1959
    • terms and conditions for any agreements or contracts entered into between the Minister and CTP Insurers.

The Motor Accident Injury Accreditation Scheme Administrator

The South Australian Motor Accident Injury Accreditation Scheme (MAIAS) was established under Section 76 of the Civil Liability Act 1936 to accredit health professionals to undertake Injury Scale Value (ISV) medical assessments. This helps to determine an injured road user’s eligibility for compensation under the CTP Scheme.

The Regulator has been appointed as the MAIAS Administrator, with administrative and financial responsibility of the MAIAS.

A key objective of the MAIAS is to create an independent system that provides consistent, objective and reliable ISV medical assessments.

The MAIAS Administrator uses the MAIAS Scheme Rules to oversee the performance of the medical practitioners. The rules prescribe the regulatory and service standards required for medical practitioners to achieve and maintain accreditation.
