The Act imposes a web of duties and rights calibrated to promote the objects in s 1.3, with explicit interpretive mandates preferring constructions that advance those objects (s 1.3(4)) and requiring discretions to be exercised accordingly (s 1.3(5)). Key duties include:
-
Duties on claimants: Minimise loss by undertaking reasonable treatment and returning to work (s 6.5, with suspension of benefits for non-compliance). Provide authorisations, medical evidence, and certificates of fitness (ss 3.14–3.15), notify changes in circumstances (s 3.18, penalty 20 penalty units), and co-operate fully (s 6.24). Claims must be verified (s 6.8), given within time limits (ss 6.13–6.14, with full and satisfactory explanation for delays per s 6.2), and include all relevant particulars (s 6.25). For damages claims, settlement requires legal representation or Commission approval (s 6.23). Fraudulent claims trigger remedies (s 6.42), including recovery of benefits.
-
Duties on insurers: Act in good faith (s 6.3(3)), including providing information on entitlements, reasons for decisions, and prompt payment. Determine relevant insurer status (s 3.2) and accept liability within 4 weeks for initial benefits and 9 months for post-52 weeks (s 6.19, deemed acceptance if not notified). Make reasonable offers of settlement (s 6.22) and comply with notice before reducing benefits (s 3.19, penalty 50 penalty units, with refund rights). File premiums per Guidelines (s 2.20), disclose profits (s 2.23), and participate in risk equalisation (s 2.24). As licence condition, comply with Guidelines (s 10.7), internal reviews (Division 7.3), and dispute processes (Part 7). For Nominal Defendant claims, allocate to licensed insurers per Insurance Industry Deed (s 2.36).
-
Duties on owners/drivers: Ensure insurance (s 2.1 offence), co-operate with insurers (s 6.28, penalty 20 penalty units for failure to furnish information), and not admit liability without consent (s 6.16). Unauthorised drivers face recovery actions (s 2.16).
-
Rights of injured persons: Statutory benefits without proof of fault (s 3.1), including weekly payments (ss 3.6–3.8, minimum amounts per s 3.10), treatment and care (s 3.24, with Guidelines on reasonableness), and funeral expenses (s 3.4). For serious injuries, right to damages for economic and non-economic loss (Part 4), subject to thresholds (s 4.4 no damages for threshold injuries; s 4.11 >10% impairment). Access to merit reviews (Division 7.4), medical assessments (Division 7.5, conclusive per s 7.23), and claims assessments (Division 7.6). Vocational support (s 3.41) and trauma support (s 11.1A, inserted 2022). Protection from costs penalties for unreasonable denials (s 6.21).
-
Rights of insurers: Reject or reduce benefits for threshold injuries, at-fault driving, or serious offences (ss 3.11, 3.28, 3.36–3.37). Recover overpayments (s 3.43) or from at-fault uninsured parties (s 2.37). Intervene in proceedings (s 6.18) and rely on binding assessments (s 7.23 for medical; s 7.14 for merit reviews). Nominal Defendant has recovery rights (s 2.37) and joinder powers (s 2.34).
-
Regulatory and Commission rights: Authority issues Guidelines (Division 10.2, binding per licence conditions), manages funds (ss 10.12, 10.14), and conducts audits/investigations (Division 10.6). Commission resolves disputes (Part 7), with President appointing assessors/reviewers. Medical assessors determine impairment (s 7.21) and treatment (s 7.20).
These are enforced through offences (e.g. false claims, s 6.40, 500 penalty units or 2 years imprisonment), licence conditions (Part 9), and dispute mechanisms. For example, s 3.38 mandates contributory negligence findings for specified conduct (alcohol offences, no seatbelt), with regulations fixing percentages. Court challenges, such as those testing 'threshold injury' (s 1.6, soft tissue excluding nerve damage or ruptures), illustrate the balance: claimants have rights to assessments (s 7.20), but insurers benefit from conclusive certificates (s 7.23).
The 2022 amendments refined these, e.g. expanding threshold injuries (Schedule 1[15]–[18]) and adjusting cessation rules, reinforcing duties while preserving core rights. In expert practice, compliance requires rigorous file management, timely evidence (ss 3.14–3.15), and awareness of Guidelines on earning capacity decisions (s 3.16).
