Navigating Your WA or SA Claim
Western Australia and South Australia sit within the broader WorkCover certificate topic, but they operate separate workers compensation systems with different certificate names, claim processes and certification rules.
In WA, WorkCover WA uses First, Progress and Final Certificates of Capacity. In SA, ReturnToWorkSA uses its own Work Capacity Certificate process. The correct pathway depends on the state where the workers compensation claim is being managed.
This page compares the two schemes so you can identify the correct form, issuer pathway, capacity information and submission process before arranging an assessment.
Key Facts
WA certificate system
WorkCover WA uses First, Progress and Final Certificates of Capacity.
SA certificate system
ReturnToWorkSA uses the Work Capacity Certificate and encourages electronic certification.
Different claim pathways
The form and submission process must match the state scheme handling the claim.
Capacity focused
Both systems focus on current functional capacity, restrictions and recovery at work.
How Does Workers Compensation Work in WA?
WorkCover WA regulates Western Australia's workers compensation and injury management scheme. A worker starting a claim provides a Workers Compensation Claim Form together with a First Certificate of Capacity completed by their treating medical practitioner.
The medical practitioner's role is to assess the injury, treatment and work capacity. The practitioner does not decide whether the compensation claim itself is accepted; liability is determined through the insurer's claims process.

RiskCover is the Western Australian Government's self-insurance fund for participating government agencies. WorkCover WA remains the regulator of the broader WA workers compensation scheme.
A WA Government worker covered through RiskCover should follow their agency's claim instructions. A First Certificate of Capacity completed by a medical practitioner remains part of the government-employee claim process.

South Australia's Work Capacity Certificate
ReturnToWorkSA uses a Work Capacity Certificate to document a medical assessment of a work injury, the worker's functional abilities, capacity for work, treatment and recovery planning.
The standard Work Capacity Certificate must be completed by a medical practitioner. ReturnToWorkSA encourages doctors to use its electronic Work Capacity Certificate where available.
Check ReturnToWorkSA Work Capacity Certificate guidanceSA issuer exception
A nurse practitioner in a hospital emergency department can issue the separate Nurse Practitioner Work Capacity Certificate for a new work injury for up to seven calendar days. Only one can be issued per patient per injury event; further certification requires a medical practitioner.
Western Australia's First, Progress and Final Certificates
The First Certificate of Capacity is completed by the treating medical practitioner when the worker first seeks treatment and is used with the claim form to initiate a workers compensation claim.
The treating medical practitioner uses Progress Certificates for later consultations to update treatment, recovery and capacity. A Final Certificate is generally used when the worker is fully fit and no longer requires treatment, or where the condition is unlikely to change materially over the relevant longer-term period.
WorkCover WA certificate guidanceWA certificate stages
- First Certificate of Capacity - starts the claim pathway
- Progress Certificate of Capacity - updates recovery and work capacity
- Final Certificate of Capacity - records the final capacity stage
Do Not Transfer One State's Rules to the Other
WA's First, Progress and Final structure is not the South Australian certificate structure. South Australia uses its own Work Capacity Certificate and claims-agent process.
Use the form and instructions for the state where the claim is being managed rather than adapting another jurisdiction's certificate.
Functional Capacity Matters in Both Schemes
The practitioner should describe clinically supported capacity in practical terms, including what work may be safe, relevant restrictions, treatment and expected recovery or review information.
The exact fields and capacity options must still follow the WA or SA form rather than one generic OMC certificate format.
WA and SA Use Different Certificate Systems
Western Australia and South Australia should be treated as two separate workers compensation systems on this page. The comparison below shows where the important differences occur before a worker arranges an assessment or submits a certificate.
WorkCover WA Certificates of Capacity
Scheme authority
WorkCover WA regulates the Western Australian workers compensation and injury management scheme.
Certificate / form name
First Certificate of Capacity, Progress Certificate of Capacity and Final Certificate of Capacity.
First and later certificates
The treating medical practitioner completes the First Certificate for the initial claim and uses Progress Certificates during subsequent consultations. A Final Certificate is used at the final capacity stage.
Capacity information
The certificate records work capacity, the extent of incapacity where relevant, duties the worker may perform, restrictions, treatment and injury-management needs.
Where the first certificate goes
The worker gives the First Certificate and completed claim form to the employer. The employer then lodges the documents with its insurer under the WA claim process.
ReturnToWorkSA Work Capacity Certificate
Scheme authority
ReturnToWorkSA administers and regulates South Australia's Return to Work scheme, with claims managed through claims agents or self-insured employers as applicable.
Certificate / form name
Work Capacity Certificate, with an electronic Work Capacity Certificate available for medical practitioners.
First and later certificates
The standard Work Capacity Certificate is completed by a medical practitioner. A hospital emergency-department nurse practitioner has a separate limited certificate for a new injury, for up to seven days and once per injury event; further certification requires a medical practitioner.
Capacity information
The SA form distinguishes recovery to normal duties, capacity for suitable duties that match functional abilities, and medical unfitness for suitable duties while recovering.
Certificate and claim submission
ReturnToWorkSA encourages electronic Work Capacity Certificates. Lodging a certificate alone does not make a compensation claim; the injured worker also needs to notify the employer so the applicable claims process can begin.
The doctor assesses capacity, not claim acceptance
In both states, medical certification supplies clinical and work-capacity information. Whether a workers compensation claim is accepted and what compensation is payable are separate decisions made through the applicable scheme and insurer process.
For ordinary illness or injury that is not part of a workers compensation claim, workplace evidence follows a different pathway. See Fair Work's workers compensation overview.

What to Bring to a WA or SA Capacity Assessment
Have the state where the claim is being managed, employer and insurer or claims-agent details, injury history, current work duties and relevant treatment information ready.
If you already have a claim number, insurer correspondence, an existing capacity certificate or a state form, have those available so the practitioner can identify the correct scheme pathway and current capacity context.
Bring these details
- WA or SA claim jurisdiction
- Employer, insurer or claims-agent information
- Injury, treatment and current job-duty information
How These Forms Differ From a Standard Sick Leave Certificate
A standard sick leave certificate generally addresses incapacity for ordinary workplace absence.
WA Certificates of Capacity and the SA Work Capacity Certificate form part of workers compensation processes and contain additional information about the work injury, functional capacity, treatment, restrictions and recovery at work.
Who Can Issue and Manage the Claim?
The certificate issuer and the organisation deciding the claim are not the same thing. The practitioner makes the clinical capacity assessment, while the insurer, claims agent or self-insurer manages liability and compensation decisions.
For a broader explanation of certificate issuers, see who can issue workers compensation capacity certificates.
When Capacity Changes During the Claim
Capacity evidence should change when the clinical picture changes. Restrictions, safe duties, working hours, treatment and review requirements should reflect the worker's actual current function rather than a predetermined recovery schedule.
WA records this progression through its First, Progress and Final certificate stages. SA uses its Work Capacity Certificate to update functional capacity and recovery planning over time.
Capacity information can change
- Work duties that can be performed safely
- Hours, restrictions and functional tolerances
- Treatment and review requirements
WA Progress and Final Certificates
The treating medical practitioner uses a Progress Certificate to update recovery, treatment and capacity after the initial WA consultation.
A Final Certificate is usually issued when the worker is fully fit and no longer requires treatment, or where the condition is unlikely to change materially in the next 12 months.
SA Certification Over Time
South Australia does not use WA's First, Progress and Final naming structure. The Work Capacity Certificate focuses on the worker's current functional abilities and the treatment and recovery information relevant at the time of assessment.
A nurse practitioner's limited new-injury certificate is not an ongoing-certification pathway; further certification after that exception requires a medical practitioner.
Claim Acceptance and Payments Are Separate Decisions
A capacity certificate does not itself approve a workers compensation claim or guarantee weekly payments. Liability and compensation decisions are made through the insurer, claims agent or self-insurer under the applicable state scheme.
In WA, workers may need to meet expenses while a claim is being assessed and seek reimbursement if the claim is accepted. Follow the specific payment instructions provided for the WA or SA claim.
Working With the Claim Team
The employer, insurer or claims agent and treating team use current capacity information to coordinate treatment and recovery-at-work planning.
The practitioner provides the clinical assessment; the claim parties apply that information under the relevant WA or SA scheme.
Western Australia Information by Location

South Australia Information by Location
For broader state information outside the workers compensation claim itself, view OMC Health information for South Australia.
Certificate Verification
Where OMC Health issues a document with OMC verification details, those details can be used to confirm the OMC-issued document is genuine. Verification does not replace the WA or SA scheme's requirements for its workers compensation form.
Frequently asked questions
View all FAQsA First Certificate starts your WA claim, Progress Certificates track your recovery over time, and a Final Certificate confirms either a full return to normal duties or a stable, ongoing level of capacity.
No. South Australia's ReturnToWorkSA scheme uses its own specific certificate format and process, distinct from WA's First, Progress and Final Certificate structure, so the two shouldn't be assumed interchangeable.
In WA, the First Certificate is issued by a medical practitioner, with other approved treating practitioners able to issue subsequent certificates. SA has its own specific requirements under ReturnToWorkSA, which are worth checking separately.
WorkCover certificates in WA and SA follow their respective state schemes, administered by WorkCover WA and ReturnToWorkSA, respectively. Both require a certificate of capacity from a registered medical practitioner, with requirements that differ from the eastern states.
