Yes—under Northern Territory legislation, a principal contractor can be liable for workers’ compensation claims made by workers of its subcontractors. It is also entitled to indemnification from those subcontractors, but that indemnity should not be treated as removing the principal’s statutory exposure.
Figures checked 1 October 2026 against the NT WorkSafe source dated 5 January 2023: Workers compensation insurance requirements for employers.
What does the principal-contractor rule mean for a cleaning business?
If a cleaning principal engages a subcontractor and a subcontractor’s worker makes a workers’ compensation claim, the principal may be liable even though another business engaged the worker.
The legislation deals with two connected issues:
- Claims exposure: the principal contractor is liable for claims by workers of its subcontractors.
- Recovery from the subcontractor: the principal contractor is entitled to be indemnified by those subcontractors.
These issues can coexist. The right to indemnification may help the principal recover costs, but it does not mean subcontractor status or a policy document automatically removes the principal from the claim process.
Does subcontractor insurance remove the principal’s liability?
Subcontractor insurance is important, but it should not be treated as the principal’s only safeguard. NT WorkSafe advises principals to make sure subcontractors have workers’ compensation insurance for their workers and separately advises principal contractors to maintain their own insurance in case of an oversight.
A sensible risk-control approach is to:
- Obtain evidence that each subcontractor has workers’ compensation cover for its workers.
- Have the policy information reviewed for relevance to the cleaning work and the Northern Territory.
- Keep records of the subcontractor’s status, insurance information and contractual indemnity terms.
- Maintain appropriate principal cover.
- Ask an insurance broker or adviser to assess any uncertainty.
The cited NT WorkSafe guidance does not say that presenting an insurance certificate automatically removes a principal contractor’s statutory liability.
What should be checked before cleaning work starts?
Before engaging a subcontractor, check both the insurance arrangement and the legal relationship between the businesses.
Subcontractor cover
Ask for current evidence of workers’ compensation insurance and have the relevant policy terms reviewed. The important questions are whether the cover fits the work, the worker arrangement and the territory in which the cleaning will occur.
Do not rely only on a business being described as a subcontractor. NT WorkSafe says a person determined to be an employee using Australian Taxation Office guidance should be covered for workers’ compensation even if the employer considers the person to be a contractor.
Contract and indemnity terms
The statutory entitlement to indemnification exists alongside the principal’s liability. A broker or adviser should review the contract to check that its indemnity wording appropriately reflects the statutory position and explain how recovery may be pursued.
Principal cover
NT WorkSafe advises principal contractors to maintain their own insurance in case of an oversight. The appropriate cover depends on the business’s role, whether it employs workers and the terms of the relevant policy, so a label such as “principal contractor” should not be used as the only basis for a coverage decision.
When should a broker or adviser review the position?
Professional assistance is particularly useful when:
- it is unclear whether a person is an employee or a contractor;
- a subcontractor’s policy does not clearly match the work or territory;
- the contract and insurance respond differently to a claim;
- the principal’s own coverage is unclear;
- indemnification needs to be enforced or recovery is disputed.
Workers’ compensation insurance can be obtained by contacting an insurance broker. The current NT approved-insurer information should also be checked on the regulator page.
This is general information, not financial or legal advice. Check the NT WorkSafe regulator page and the relevant policy’s Product Disclosure Statement before relying on a coverage or indemnity arrangement.

FAQ
Does a signed subcontractor contract remove the principal’s liability?
A contract should not be assumed to do so. The NT legislation makes the principal liable for subcontractor workers’ claims while also providing for indemnification from the subcontractors. Have the contract and policy terms reviewed rather than treating either document as automatically eliminating the principal’s exposure.
Can the principal recover claim costs from the subcontractor?
The legislation entitles the principal contractor to be indemnified by the subcontractors. The practical recovery process can depend on the contract and circumstances, so obtain advice before assuming that a particular cost can be recovered.
Should the principal still maintain its own insurance?
NT WorkSafe advises principal contractors to maintain their own insurance in case of an oversight. Appropriate cover should be confirmed with a broker or adviser and assessed against the relevant policy PDS.
Is there a claim amount or worker-count threshold in the cited guidance?
The cited NT WorkSafe page states no claim amount, worker-count or contract-value threshold. That does not remove the need to check the current regulator guidance and obtain advice on the particular arrangement.
What if both businesses believe the worker is a contractor?
The label alone does not settle the issue. NT WorkSafe says a person determined to be an employee under Australian Taxation Office guidance should have workers’ compensation cover even if the employer thinks the person is a contractor.
