The Victoria TAC scheme.

Victoria's Transport Accident Commission (TAC) administers one of the longest-running and most comprehensive no-fault transport injury compensation schemes in the world. Established by the Transport Accident Act 1986 (Vic) and operational from 1 January 1987, the scheme replaced an earlier MAIB-style fault-based motor vehicle compensation framework with a hybrid model: statutory no-fault benefits for all injured persons, plus a residual common-law damages action limited to those who can establish a serious injury.

The scheme was the product of the Cain Labor government's 1986 reform of third-party motor insurance, which followed sustained increases in CTP premiums and dissatisfaction with the prior tort-only model. Funded by an annual Transport Accident Charge collected with vehicle registration (rather than risk-rated insurance premiums), the TAC is administered as a Victorian government-owned statutory authority and reports to the Victorian Treasurer.

Nearly four decades on, the TAC is widely regarded across Australia as the gold standard for catastrophic injury support — the lifetime, uncapped funding model for severe acquired brain injury and spinal cord injury preceded and informed both the National Disability Insurance Scheme and the National Injury Insurance Scheme proposals. The serious injury threshold has been the subject of extensive County Court and Court of Appeal jurisprudence and remains central to scheme design.

Before reform: the pre-1986 regime

Before 1987, motor vehicle injury compensation in Victoria operated on a fault- based tort model with limited first-party medical accident benefits. CTP premiums had risen sharply through the early 1980s, scheme reserves were under pressure, and treatment of long-term catastrophic claimants was widely inadequate. The Cain government commissioned reviews that ultimately produced the 1986 Act, modelled in part on the New Zealand Accident Compensation Corporation framework and on Manitoba's no-fault automobile scheme.

The Transport Accident Act framework

The 1986 Act applies to a transport accident — broadly, an incident directly caused by the driving of a motor vehicle, railway train, tram, or (in defined circumstances) a bus or aircraft. Section 35 establishes the no- fault entitlement to medical, rehabilitation, income, and impairment benefits. Section 93 establishes the gateway to a common-law damages claim, restricted to persons with a serious injury as there defined.

The TAC is the sole insurer for transport accidents in Victoria and the sole counterparty for both statutory benefits and any subsequent common-law claim (subject to its rights of subrogation and contribution). This integrated single- insurer architecture is a defining feature of the scheme and accounts for much of its administrative coherence.

Statutory benefits

Loss of Earnings benefits are subject to a statutory maximum (indexed annually) and to a small initial excess for the first five days. Treatment must be reasonable, necessary, and approved (or approvable) by the TAC, with detailed policies governing equipment, mental health treatment, and out-of-area care.

The serious injury threshold

Section 93 of the Act precludes common-law damages unless the claimant establishes a serious injury. There are two pathways:

1. The deemed pathway — whole person impairment of 30% or more, certified through the Medical Panel process. WPI is assessed under the AMA Guides 4th edition with Victorian modifications.
2. The narrative pathway — a serious injury certificate issued by the County Court of Victoria. The claimant must satisfy one of four statutory limbs: serious long-term impairment or loss of a body function, permanent serious disfigurement, severe long-term mental or behavioural disturbance, or loss of a foetus. The leading authorities — Humphries v Poljak [1992] 2 VR 129, Wilson v Mackrill, and subsequent decisions — establish that the consequences must be “very considerable and more than significant or marked”.

Most narrative applications proceed under the first limb (long-term impairment). The County Court has developed a substantial body of decisions calibrating what counts as “very considerable” in particular contexts (back, neck, shoulder, knee, psychiatric).

Common-law damages above the threshold

Once a serious injury is established, the claimant may bring a common-law damages action against the at-fault driver (defended by the TAC). Two heads of damage are recoverable: pain and suffering (general damages) and pecuniary loss damages (past and future economic loss). The Act imposes statutory minimum and maximum awards for each head, indexed annually, with a deduction for any impairment benefit already paid.

The maximum pain and suffering award and the maximum pecuniary loss damages are both capped (in the high six figures, indexed). Awards above the statutory minimum but below the maximum are determined by the County Court applying ordinary common-law principles, modified by the Act's caps.

Catastrophic and lifetime support

For severely injured claimants, the TAC funds lifetime, uncapped medical, attendant care, equipment, home and vehicle modification, and related support. The scheme's catastrophic injury cohort — concentrated in severe acquired brain injury, spinal cord injury, and high-level multi-trauma — is small in number but accounts for a disproportionate share of long-tail scheme liabilities. Independent oversight and case management are integrated into ongoing TAC administration.

Dispute resolution

Disputes about TAC entitlement decisions follow a multi-tier process: internal review by the TAC, then conciliation through the Victorian Civil and Administrative Tribunal (VCAT) for benefit decisions, with onward appeals on questions of law to the Supreme Court. Medical impairment disputes are determined by the Medical Panel under the Accident Compensation Act 1985 framework, whose certificate is binding subject to limited judicial review.

Serious injury applications under section 93 are filed in the County Court of Victoria. Common-law damages proceedings, where serious injury is established (by consent or certificate), also proceed in the County Court.

Comparison to other Australian schemes

The TAC scheme is more generous than NSW under the MAIA 2017on statutory long-tail benefits and on catastrophic-injury lifetime funding, but uses a much higher tort gateway (30% WPI or narrative test versus NSW's 10% WPI for non-economic loss). Compared to Queensland's CTP scheme, Victoria provides materially better first-party benefits but tighter common-law access. The Northern Territory and Tasmania each operate their own variants.
