Quick answer
Treat the change as a practical evidence step, not an automatic full return to work.
If your NSW workers compensation certificate changes from no current work capacity to some capacity, ask what the certificate actually permits: days, hours, duties, lifting, sitting, standing, driving, medication limits, travel, psychological triggers and upgrade timing. The insurer and employer may use the certificate to plan suitable duties, but the duties still need to match the medical restrictions and be safe in the real workplace.
This information is general and is not legal advice. If weekly payments, treatment, suitable duties or a work capacity decision are in dispute, get advice on your own facts before missing a deadline or refusing duties.
First, read the certificate line by line
Do not only look at the tick box. Check the diagnosis, capacity section, restrictions, certified hours, review date and any comments about treatment or graduated return to work. A certificate that says “some capacity” but leaves the hours or restrictions vague can create avoidable disputes.
SIRA material describes the certificate of capacity as a document used to describe the injury, capacity for work and treatment required for a safe and durable recovery. It also helps the insurer, worker and employer develop an injury management plan and identify suitable work adjustments. That is why specific restrictions matter.
Ask for the actual duties before agreeing they are suitable
A capacity certificate is not the same as a safe duties plan. Ask the employer or rehabilitation provider to write down the proposed tasks, hours, start and finish times, breaks, supervision, location, equipment and any travel requirement. Compare each item with the certificate and your treatment provider's current advice.
If the task list does not match the certificate, respond in writing. Be specific. For example, say which duty exceeds the lifting limit, which shift length exceeds certified hours, or why the proposed travel conflicts with medication or sitting limits. Avoid broad statements such as “I cannot do it” unless your medical evidence clearly says that.
Get clarification quickly if the certificate is unclear
If the certificate changed unexpectedly, book a review with the practitioner who issued it. Ask them to clarify whether “some capacity” means a short trial, restricted hours, office-based duties only, no customer contact, no driving, no overtime, no heavy lifting, or another practical limit. If there is a psychological injury, ask whether triggers, supervision arrangements and communication limits should be recorded.
Keep the request neutral. You are not asking the doctor to write what you prefer. You are asking for the certificate to reflect the real medical restrictions so the return-to-work plan can be safe and accurate.
Evidence to gather before the insurer relies on the change
- the new certificate and the previous certificate showing the change;
- treatment notes or a short report explaining the reason for the change;
- the proposed suitable duties plan, including hours and task descriptions;
- photos, rosters, position descriptions or equipment details if they show why duties may be unsafe;
- a symptom and tolerance diary for any trial period, focused on work tasks rather than general complaint;
- written questions sent to the insurer, employer or rehabilitation provider and their replies.
What if the employer offers duties straight away?
If the duties appear to match the certificate, ask for the plan in writing and follow the certified limits. If the duties do not match the certificate, raise the mismatch before the shift where possible. Ask the employer to modify the duties or get medical clarification rather than turning a medical issue into a conduct dispute.
If you try suitable duties and symptoms flare, report the specific task, duration and effect promptly. A short factual note is usually more useful than a general complaint. For example: “After 40 minutes standing at the bench, pain increased and I needed to sit, which conflicts with the standing tolerance noted by my treating practitioner.”
What if weekly payments are reduced?
A certificate showing some capacity can affect how the insurer assesses weekly payments, especially if the insurer says you can earn wages in suitable employment. Ask for the calculation and the reasons. Check whether the assumed hours, duties, earning capacity and job availability match the medical restrictions and the real work offered.
If the insurer issues a work capacity decision or dispute notice, do not answer it with general disagreement only. Build a response around the certificate, the actual duties, the medical restrictions and any incorrect earning assumptions. Deadlines can be short, so get advice early if payments have been reduced or stopped.
Short wording you can adapt
“My certificate now records some capacity, but I need the proposed duties to be matched to the certified restrictions before I can comment on whether they are suitable. Please provide the task list, hours, location, breaks, supervision and any travel requirement. I am also asking my treating practitioner to clarify the practical restrictions so the return-to-work plan is accurate.”
Official source basis
This article was checked against SIRA public material on certificates of capacity for workplace injuries, SIRA claims management glossary material for certificates of capacity, SIRA guidance for medical practitioners completing certificates, and the NSW workers compensation work capacity and suitable employment framework. Direct official page access can be intermittent, so the wording above stays conservative and does not say that a certificate change guarantees payments, duties, treatment approval or dispute outcomes.
