Certificate of Capacity NSW: What It Means
If you have been hurt at work in New South Wales, the certificate of capacity NSW doctors issue is the document that keeps your claim moving. It tells your employer and the insurer what work you can do right now, what you cannot, and what treatment you need. Weekly payments, suitable duties and approval for physiotherapy all hang off it.
Most workers meet the form on day two or three of a claim, usually with no explanation of how it works. Here is what it actually contains and how it affects your rehab.
Who issues the certificate
Your nominated treating doctor issues it. That is the GP or specialist you have chosen to manage your injury, and their name goes on the claim. A hospital or after-hours doctor can issue the first certificate, but the ongoing ones should come from the doctor coordinating your care so the picture stays consistent.
Physiotherapists do not issue certificates of capacity. What we can do is give your doctor specific, current information about your movement, strength and tolerance for tasks, so the restrictions written on the form match what your body is doing in the gym and at the clinic rather than what it was doing three weeks ago.
What is on the form
The certificate covers a short list of things, and each one matters:
- Diagnosis and injury details. What the doctor believes is going on, and how it happened.
- Capacity for work. One of three findings: fit for pre-injury duties, fit for suitable duties with restrictions, or no current capacity for any work.
- Restrictions. Hours per day, days per week, lifting limits, and specific task limits like no ladder work, no repeated overhead reaching, no driving over a set distance.
- Treatment. Referrals and the treatment the doctor supports, which is where physiotherapy or exercise physiology gets named.
- Dates. The period the certificate covers, and the date of examination.
- Consent. A section authorising release of information about your injury to the insurer and employer.
The restrictions section is the part workers tend to skim and then regret. Vague wording like "light duties only" leaves your employer guessing, and guessing usually means you sit in a back office doing nothing useful. Specific wording gives your employer something to build a roster around.
How long a certificate lasts
A certificate of capacity can generally cover a period of up to 28 days. Longer periods are possible only in limited circumstances, so in practice you will be back at the doctor roughly monthly, and more often early on when things are changing quickly.
Keep the certificates continuous. A gap between the end date of one and the start date of the next can hold up weekly payments while it gets sorted out. Book the next GP appointment before the current certificate expires rather than on the day it runs out.
How the certificate shapes your physiotherapy
The restrictions on your certificate set the boundaries your rehab works inside. If the form says no lifting over 5kg from floor to waist, your program should be building toward that lift under control, not avoiding hinge patterns entirely for six weeks and then hoping for the best.
In a SIRA-registered physiotherapy setting, the certificate does three practical things:
- It confirms the injury is being managed as a workers compensation claim, which is what lets treatment be billed to the insurer rather than to you.
- It records that your doctor supports physiotherapy, which supports the treatment request sent to the insurer.
- It gives us a work target. A concreter cleared for four hours a day with no jackhammer use needs a different program to an office worker cleared for full hours with sit-stand breaks.
Bring a copy or a photo of your current certificate to your first appointment. It saves phone calls.
When your capacity changes mid-certificate
Capacity is not fixed for 28 days just because the paper says so. If your shoulder starts tolerating overhead work at week two, you do not have to wait until week four to get the restriction lifted, and if a duty is aggravating the injury, you should not push through to the review date.
Tell your doctor. A supporting note from your physiotherapist on your current measured range, strength and task tolerance gives them something objective to work with, and an updated certificate can be issued. The same applies in reverse: if a duty is flaring things up consistently, that belongs on the record, not in your head.
Common hold-ups
- Certificate lists duties your employer does not have. Ask your doctor to write restrictions by task and tolerance rather than naming a job title.
- Restrictions never change. Repeating the same certificate for months without review tends to stall a claim. Progress should be reviewed against how you are actually functioning.
- Treatment approved on the certificate but not with the insurer. The doctor supporting physiotherapy and the insurer approving it are two separate steps.
- No copy kept. Photograph every certificate. Claims involve more paperwork than anyone expects, and pages go missing.
Where our role sits
We work with your nominated treating doctor, your employer's return-to-work coordinator and the insurer, using the certificate as the shared reference point. Assessment covers the injured area, how it is behaving under load, and the specific physical demands of your job, and the program is built from there. Progress notes go back to your doctor so the next certificate reflects current findings.
If you are managing a work injury in Five Dock or the wider Inner West and your certificate of capacity does not match what you can do, bring it in and book an assessment so we can look at it with you.
