What is section 43 in NSW workers compensation?

Section 43 deals with work capacity decisions by insurers. It sits at the centre of decisions about your current work ability, suitable employment, and your likely earnings for weekly payment purposes.

Why do section 43 decisions reduce weekly payments?

Insurers often rely on section 43 findings to argue you can perform suitable employment or earn more than you currently do. That can reduce your weekly rate or support stopping payments entirely.

What should I do first after receiving a section 43 decision?

Request all decision reasons and relied-upon documents immediately, then obtain updated treating evidence with specific restrictions. Early evidence framing is critical before internal review and commission escalation.

Why should I confirm the insurer legal entity before lodging review papers?

Section 43 review requests are often delayed when papers are sent to the wrong legal entity or decision team. Confirming the exact insurer decision-maker on day one helps preserve deadlines and reduces avoidable processing setbacks.

What if the insurer brand name on a phone call differs from the legal entity on my notice?

Do not guess the recipient. Ask for written confirmation of the exact legal entity and review team, then send your review papers to that named entity and keep delivery proof. This avoids misdelivery delays and protects your review timeline.

Work capacity disputes

Section 43 work capacity decision NSW: what insurers must consider

Work capacity decision review pathway with decision material, capacity certificates, duties evidence, wage records, and review pathway papers arranged without readable text. — Work-capacity disputes are clearer when capacity certificates, duties evidence, decision notices, and review steps are kept on one pathway.

Direct answer: a section 43 work capacity decision is the insurer's written decision about your current work capacity, suitable employment, and earning capacity for weekly payment purposes. It can reduce or stop weekly payments if it relies on assumptions that you can work more hours, perform different duties, or earn more than your medical evidence realistically supports. The safest response is to test the written reasons against your Certificate of Capacity, treating evidence, actual job demands, and the insurer's vocational material before you lodge any review request.

Quick answer: what to do in the early triage stage

Get the insurer's full written reasons and relied-on documents, then lock your response around three issues: functional restrictions, realistic suitable-employment options, and earnings assumptions. If any of those are weakly evidenced, prepare your challenge before the next pay cycle and map your escalation via the section 44 internal review pathway.

Where section 43 fits in your claim strategy

Section 43 is usually the legal bridge from medical restrictions to insurer decisions about earnings, suitable duties, and whether payments stay at the same rate. If the insurer gets this step wrong and you do not challenge it quickly, that mistake can flow into section 44 review outcomes and later PIC disputes.

Start with the work capacity disputes guide and then sequence evidence for the section 44 internal review process.

Common section 43 decision errors

Suitable employment assumptions that do not match your training, restrictions, or local job reality.
Earnings estimates based on theoretical work rather than actual labour-market conditions.
Overweighting one insurer medical opinion while downplaying treating specialist evidence.
Insufficient explanation of why contrary evidence was rejected.

If payments are already reduced, cross-check rates under section 37 weekly payment rules and use the urgent response checklist in weekly payments stopped.

Evidence to check before asking for review

A strong response usually separates medical capacity, real duties, and earning assumptions instead of arguing everything at once. Compare the insurer's reasons with your most recent Certificate of Capacity, specialist reports, treating notes, pre-injury duties, roster pattern, and any recovery at work plan. If the decision assumes suitable employment, ask what role, hours, restrictions, location, training, and likely earnings were actually used. If the decision relies on a labour-market or vocational assessment, request the material and check whether it deals with your restrictions and work history rather than a generic job title.

Medical evidence: functional restrictions, capacity for hours, medication effects, flare patterns, and treatment plans.
Work evidence: real task demands, manual handling, travel, shift pattern, supervision, and modified-duties history.
Earnings evidence: payslips, rosters, allowances, overtime history, and any dispute about PIAWE or current earnings.
Insurer material: written reasons, vocational reports, IME opinions, surveillance references, and calculations used to set the weekly rate.

If earnings are part of the problem, read this page alongside the weekly payments hub and the PIAWE recalculation guide. If the dispute is really about the job the insurer says you can do, cross-check the suitable employment guide before finalising review submissions.

First 14 days after a section 43 decision

Day 1–2: request full reasons, vocational material, and any medico-legal reports relied upon.

Day 3–6: obtain updated GP/specialist evidence with clear functional restrictions and capacity limits.

Day 7–10: gather wage records and role history to challenge unrealistic earning-capacity assumptions.

Day 11–14: finalise internal review submissions and prepare escalation pathway to the PIC if needed.

For escalation planning, use the PIC disputes process guide and align timelines with the work capacity review timeline. Also confirm the actual insurer decision-maker early using the NSW insurer directory so your review request is sent to the right team on day one.

If the insurer trades under one brand name but your notice identifies a different legal entity, request written confirmation of the exact legal recipient before you lodge review papers. Keep that email with your delivery receipt as part of your timeline record.

When to get advice before lodging papers

Get advice early if the decision changes your weekly payments, relies on an IME report that conflicts with treating evidence, says you can perform a job you have never done, or uses earnings figures you cannot trace. Also be careful if there are overlapping issues such as a section 78 liability dispute, proposed return to work duties that do not match restrictions, or a looming section 39 weekly payments issue. Those issues can interact, so a short review request that only responds to one assumption may leave other factual errors untouched.

Keep the response conservative and evidence-based. Avoid guessing about what the insurer meant. Quote the exact part of the decision you dispute, identify the document that contradicts it, and state what further document you need if the insurer has not disclosed the basis for the finding.

What usually goes wrong before a section 43 dispute lands

The treating doctor certificate is too generic, so capacity assumptions go unchallenged.
Workers focus on medical symptoms but do not rebut earnings and labour-market assumptions.
Insurer reasons are accepted at face value without obtaining the vocational documents behind them.
Internal review timing is missed, forcing a harder and slower escalation path.
