In South Australia, workers compensation insurance is provided by ReturnToWorkSA, which both insures employers and regulates the Return to Work scheme. You must register within 14 days of employing someone, unless you'll pay your workers less than $16,806 in total in 2026-27. The average premium rate for 2026-27 is 1.85%, held at that level for the fourth year in a row.
ReturnToWorkSA insures you directly, while two claims agents, EML and Gallagher Bassett, manage claims. There's no insurer to choose, so the useful things to understand are the registration threshold, the premium formula and its discounts, and who counts as a worker, including directors and some self-employed contractors the Act deems to be workers.

ReturnToWorkSA describes itself as providing work injury insurance and regulating the South Australian Return to Work scheme. Employers register with it directly rather than buying from an insurer. Claims are managed by two claims agents, EML and Gallagher Bassett, on ReturnToWorkSA's behalf, and some large employers are self-insured. Workplace safety is a separate job, handled by SafeWork SA.
With one insurer and a published formula, there's no price comparison to run for SA workers compensation. The things that change what you pay are your industry classification, the remuneration you declare, your size and your claims.
ReturnToWorkSA says you must register for work injury insurance within 14 days of employing. The exception is a small wage bill: if you will pay your workers less than $16,806 in total for the 2026-27 financial year, you don't need to register. The threshold is indexed, so check it each year.
The exemption has a catch. If a worker is injured while you're unregistered under the threshold, you must register and pay the minimum premium, so a business near the line may prefer to register anyway.
ReturnToWorkSA publishes its formula: Premium = BP × (1 − D) + C − A + SUR. BP is your base premium, which is your remuneration multiplied by your industry premium rate. D is a discount that depends on the size of your business. C is a claims component based on the previous year's income support costs, capped at three times D × BP. A is an apprentice incentive, and SUR is a supplementary underwriting rate that applies in some circumstances.
New employers pay the base premium for their first full year, and the minimum premium for 2026-27 is $200, plus GST and the WHS fee. Across the scheme, the average premium rate for 2026-27 is 1.85%. As an illustration of the method only, 1.85% of $100,000 of remuneration is $1,850; your own industry rate and adjustments decide your actual premium.
| Part | What it is |
|---|---|
| BP (base premium) | Your remuneration × your industry premium rate |
| D (discount) | A discount based on the size of your business |
| C (claims component) | The previous year's income support costs, capped at 3 × D × BP |
| A (apprentice incentive) | A reduction for employing apprentices |
| SUR | A supplementary underwriting rate, where it applies |
The scheme covers workers employed under a contract of service. For company owners, ReturnToWorkSA says working directors under a contract of service are workers and are covered, while directors who only receive director's fees are unlikely to be.
The Act also deems some self-employed contractors to be workers, and ReturnToWorkSA gives examples including building work (but not tiling), cleaning, taxi driving, entertainment and outwork. If you engage contractors in those fields, check whether their pay should be included in your remuneration.
The scheme insures workers, so a sole trader isn't covered for their own injuries; business.gov.au notes that workers compensation doesn't cover sole traders in any state. If you work for yourself, arrange your own accident and income cover, and register with ReturnToWorkSA as soon as you employ anyone above the threshold.
You register online through ReturnToWorkSA's registration portal or by calling 13 18 55, and you receive a certificate of registration at the end. You'll need your ABN, your business activity (which sets your industry rate) and an estimate of remuneration. ReturnToWorkSA says financial sanctions may apply to employers that fail to register when they should.
Each state and territory runs its own scheme, and an employer registers where its workers are based. If you employ people in more than one state, check each scheme, or see the eight schemes side by side.
Yes, within 14 days of employing, unless you'll pay your workers less than $16,806 in total in 2026-27. If a worker is injured while you're below the threshold, you must register and pay the minimum premium.
Your base premium is your remuneration multiplied by your industry rate, then adjusted for business size, claims costs and apprentices. The average premium rate for 2026-27 is 1.85%, and the minimum premium is $200 plus GST and the WHS fee.
Yes, and a regulator. ReturnToWorkSA provides work injury insurance to SA employers and regulates the Return to Work scheme. EML and Gallagher Bassett manage claims on its behalf.
Working directors employed under a contract of service are workers and are covered. Directors paid only director's fees are unlikely to be.
No. The scheme covers workers, not self-employed owners. Sole traders need their own personal accident or income protection cover.
1.85%, the fourth year in a row at that rate. Your own rate depends on your industry and the adjustments in the premium formula.
