Motor Accident Commission (SA) 

Act: Motor Accident Commission Act 1992 (SA).¹

Established: The Act continues a body; it does not create one. Section 4(1) provides that the State Government Insurance Commission continues — "without change of its corporate identity" — as the Motor Accident Commission, and s 4(2) that it continues as the same body corporate, with perpetual succession and a common seal. Continuation is a distinct thing from establishing a body and from requiring an appointment, and it matters: the liabilities, contracts and proceedings of the old body are those of the new one, because it is the same legal person under a new name.

Original purpose: The Commission was established as South Australia's monopoly compulsory third-party (CTP) motor vehicle insurer — every registered vehicle's CTP premium was paid to the Commission, which in turn funded injury compensation for motor accident claims.

Where the authority sits

The functions in s 14(1) are framed around winding down, not running a scheme: the first is to carry on any residual insurance business arising from the Commission's operations as the sole approved insurer under part 4 of the Motor Vehicles Act 1959, and only until that business is divested or wound up. Read the provision before assuming the Commission still does what its name suggests.

A machinery-of-government change worth flagging explicitly

South Australia's CTP scheme was reformed from 1 July 2019 to a competitive model, with private insurers licensed to underwrite CTP policies. Earlier changes, including the move away from a single government insurer, are separate events from the 2019 reform and should be dated separately. This is a genuine, significant change to the Commission's practical role — a student should not assume the Commission is still SA's day-to-day active CTP insurer without checking current arrangements. A body whose functions have been transferred by a scheme reform keeps its establishing Act, and the Act is not a reliable guide to what the body now does. The Commission's exact residual functions should be verified against current South Australian government sources before being relied on for anything beyond the Act's original 1992 purpose.

Is it a prosecuting authority?

No. The Commission is an insurer and asset-holder, not a regulator and not a prosecuting authority. Nothing in the Act confers enforcement functions on it.

How it relates to the other SA bodies

Where the reform placed a CTP insurance regulatory function, that body (not the Commission in its original monopoly-insurer form) is now the relevant one for a current CTP regulatory question. This factsheet's job is narrower: to correctly name the Commission's establishing Act and original function, and to flag — rather than silently omit — that the practical picture has since changed.

Self-check

• Have I described the Commission's original role as SA's monopoly CTP insurer, not its current one, without checking?
• Have I flagged the 2019 competitive-CTP-scheme reform explicitly, rather than presenting the Commission as still actively underwriting CTP policies today?
