When you apply for or renew liability insurance, the insurer is not only pricing a policy. It is assessing what your business does, who it works with, where it operates and what could reasonably give rise to a claim. That assessment depends heavily on the information you provide.

For Australian business owners, sole traders and contractors, liability insurance disclosure is an important part of arranging cover. If information is incomplete, outdated or misleading, the insurer may price the risk incorrectly, apply unsuitable terms or later raise issues if a claim is made. This article explains the types of information commonly requested, why accuracy matters and when business changes should be raised with an insurer or broker.

This is general information only. It does not take into account your business circumstances, legal obligations or insurance needs. If you are unsure how a disclosure obligation applies to your policy, consider speaking with your insurer, broker or a qualified adviser.

Why disclosure matters in liability insurance

Liability insurance is designed to respond to certain claims made against a business, such as allegations of injury, property damage, professional error or other insured events, depending on the policy type. Insurers assess these risks using the details supplied in proposal forms, online quote forms, renewal declarations, emails, phone calls and supporting documents.

Accurate information helps an insurer decide whether to offer cover, what premium to charge, which exclusions or endorsements may apply and what policy limit or excess is appropriate. It also helps avoid misunderstandings between what the business thinks is covered and what the insurer has actually agreed to insure.

If you are still working out what types of liability insurance may be relevant to your business, the Liability Insurance homepage provides a broader starting point for Australian trades, professions and small businesses.

The duty to take reasonable care not to make a misrepresentation

Australian insurance law and policy wording can impose disclosure-related obligations on people arranging insurance. Depending on the type of contract and circumstances, this may be described as a duty to take reasonable care not to make a misrepresentation, a duty of disclosure, or a requirement to answer insurer questions accurately and completely.

In practical terms, a business should not guess, downplay or omit information that could be relevant to the insurer's decision. If an insurer asks a clear question about your business activities, claims history, turnover or subcontractor use, the answer should be checked and updated before it is submitted.

Misrepresentation does not only mean deliberately false information. Problems can also arise where information is outdated, incomplete or based on assumptions rather than records. For example, a sole trader who has recently started subcontracting higher-risk work may need to disclose that change, even if last year's policy was arranged when they worked alone.

Information businesses are commonly asked to provide

Each insurer and policy type has its own questions, so there is no single universal list. However, liability insurance applications and renewals often ask for details in the following areas.

Business identity and structure

Insurers usually need to know the correct legal entity to be insured. This may include a sole trader name, partnership, company, trust or trading name. If the wrong entity is listed, a certificate of currency may not match contract requirements and a claim could become more complicated.

Businesses should check details such as:

• the Australian Business Number or Australian Company Number, where relevant;
• legal entity name and trading names;
• business address and operating locations;
• related entities that may need to be insured; and
• whether the business has changed ownership or structure.

Occupation, services and business activities

Occupation descriptions are particularly important in liability insurance. A broad label such as “consultant”, “builder”, “designer” or “maintenance contractor” may not be enough if the insurer needs to understand the specific work performed.

For example, a contractor who performs minor property maintenance may present a different risk from one who undertakes roofing, electrical work or structural repairs. A business consultant providing general management advice may be assessed differently from one giving engineering, financial, migration or safety advice.

When describing activities, be specific about what the business does and does not do. If a small part of your work is higher risk than the rest, it is still worth raising. Insurers may ask for the percentage of revenue from different activities, details of higher-risk tasks, licences held or contract examples.

Turnover, fees and revenue split

Turnover is commonly used as a premium and risk-rating factor. For professional indemnity insurance, insurers may also ask about professional fees. Some insurers ask for past turnover, projected turnover or a breakdown by business activity or location.

Estimates should be reasonable and based on available records. If turnover has grown significantly, if you have won a major contract or if your revenue mix has shifted into a different service line, that may be relevant at renewal or even during the policy period.

Employees, labour hire and subcontractors

Insurers may ask how many people work in or for the business, including employees, contractors, subcontractors, labour hire workers or apprentices. This can affect both liability exposure and policy terms.

Some policies treat subcontractor-related claims differently or require subcontractors to hold their own insurance. If you regularly use subcontractors, it may be important to disclose what they do, how they are supervised, whether you check their licences and whether you collect certificates of currency.

Claims, incidents and circumstances

Applications and renewals often ask about previous claims, losses, complaints, demands, disputes or circumstances that could give rise to a claim. This is especially important for professional indemnity insurance, where claims-made policy conditions can make timing and notification critical.

Businesses should avoid assuming that a matter is too small or too old to mention if the insurer asks about it. If you are unsure whether something is a claim, complaint, incident or notifiable circumstance, ask the insurer or broker before completing the form.

Locations, sites and geographic exposure

Where you work can influence liability risk. Insurers may ask whether you operate from home, commercial premises, client sites, construction sites, markets, events or multiple locations. They may also ask whether you work interstate or overseas, or whether your products or services are supplied to overseas clients.

Overseas exposure, particularly work involving foreign contracts or jurisdictions, can be a significant underwriting issue. Do not assume that an Australian policy automatically responds to work performed or claims made outside Australia.

Licences, qualifications and professional memberships

Some occupations require licences, registrations, permits or professional qualifications. Insurers may ask for these details because they help assess whether the business is authorised and competent to perform the work described.

If a licence has lapsed, a registration has changed or a key qualified person has left the business, this may need to be raised. For regulated professions, professional indemnity requirements may also be linked to industry rules or membership obligations.

Products, importing and supply chains

Businesses that manufacture, import, distribute, install or sell products may need to provide information about product types, origins, quality control, labelling, warranties and recall procedures. Product liability exposure can differ significantly between a retailer selling locally sourced goods and a business importing products under its own brand.

If your business has recently added new product lines, changed suppliers or started selling online to different markets, consider whether your insurer should be notified.

Contracts, tenders and special insurance requirements

Contracts can affect insurance needs. A client, landlord, head contractor, council or event organiser may require a certain policy limit, interested party notation, waiver, indemnity wording or certificate of currency.

An insurer may also want to know if your business accepts unusual contractual liabilities, works under principal-controlled insurance arrangements or signs contracts that increase your exposure beyond ordinary negligence. Before signing a contract, check whether the insurance requirements align with your existing cover.

Business changes that may need to be disclosed

Liability insurance is not something to set and forget. A policy arranged for last year's business may not reflect this year's work. Changes should be considered before renewal and, in some cases, during the policy period if the policy requires notification of material changes.

Examples of business changes that may be relevant include:

• adding new services, trades or professional advice areas;
• taking on larger, higher-value or higher-risk projects;
• working in new industries, sites or geographic regions;
• starting to use subcontractors or labour hire workers;
• increasing turnover or changing the revenue split between activities;
• moving from home-based work to client sites, events or commercial premises;
• importing, manufacturing or selling new product categories;
• changing business structure, ownership or trading names;
• entering contracts with different insurance or indemnity requirements;
• experiencing claims, complaints, incidents or near misses; and
• allowing licences, registrations or professional memberships to change.

A useful rule of thumb is to ask: would an insurer assess the business differently if it knew this information? If the answer may be yes, it is safer to raise the issue before assuming the existing policy is still suitable.

Renewal is not just an administrative step

Many businesses treat renewal as a quick payment decision, but renewal is often the point where information should be refreshed. A renewal invitation may be based on the insurer's existing records, which can become inaccurate over time.

Before renewing, review the business description, turnover, staff numbers, activities, policy limits, exclusions, endorsements and insured entity details. If the renewal declaration asks you to confirm that details are unchanged, do not confirm unless you have checked.

It can also be helpful to keep copies of what was submitted. Store proposal forms, renewal declarations, emails, certificates, schedules and endorsements together. This makes it easier to answer future questions and demonstrate what information was provided.

How inaccurate information may affect cover and claims

The consequences of inaccurate information depend on the policy, the law, the nature of the misrepresentation and whether the information would have affected the insurer's decision. Outcomes can vary, so businesses should avoid assuming either that an error will be ignored or that every error automatically voids a policy.

Depending on the circumstances, an insurer may:

• ask follow-up questions before offering cover;
• adjust the premium, excess, exclusions or policy terms;
• decline to offer or renew cover for certain activities;
• treat a claim differently if the undisclosed information is relevant to the claim;
• reduce a claim payment where permitted; or
• cancel or avoid a policy in serious cases, subject to the policy wording and applicable law.

For example, if a business obtains public liability insurance as a low-risk office-based service provider but later performs physical installation work at customer premises without advising the insurer, the insurer may examine whether the policy was arranged on an inaccurate risk profile if a related claim occurs.

The safest approach is to correct information as soon as you realise it may be wrong. Contact the insurer or broker, explain the issue clearly and ask what further information is required.

How to prepare accurate information before applying or renewing

Good disclosure is easier when records are organised. Before requesting quotes or completing a renewal, gather key documents and facts rather than relying on memory.

Useful preparation steps include:

1. Review your current policy schedule. Check the insured name, business description, limits, excesses, endorsements and exclusions.
2. List your actual activities. Include minor activities, seasonal work and any higher-risk tasks.
3. Check turnover and revenue split. Use accounting records where possible and note any major changes expected in the coming year.
4. Document staff and contractor arrangements. Record employee numbers, subcontractor use and any checks you perform on licences or insurance.
5. Summarise claims and incidents. Include formal claims, complaints, demands, disputes and circumstances that could reasonably develop into a claim.
6. Review contracts. Identify insurance clauses, required limits, indemnities, interested party requirements and certificate of currency requests.
7. Confirm licences and qualifications. Make sure registrations, permits and professional memberships are current where relevant.
8. Ask questions before submitting. If a question is unclear, seek clarification rather than guessing.

Working with a broker on disclosure questions

A broker can help you understand what information insurers commonly request and how to present your business activities clearly. A broker cannot remove the need for accurate information, but they may help identify gaps, ask follow-up questions and approach insurers that consider your occupation or risk profile.

If you use a broker, be open about unusual contracts, prior incidents, higher-risk tasks and changes in the business. Withholding information from a broker can still lead to problems because the insurer may never receive the full picture.

Practical checklist: what to review before you submit

In Conclusion 

Disclosure is a core part of arranging liability insurance in Australia. Whether the obligation is framed as taking reasonable care not to make a misrepresentation, a duty of disclosure or a requirement to answer questions accurately, the practical message is similar: provide clear, current and complete information.

Business changes matter. New services, higher-risk work, subcontractors, turnover growth, claims history, product changes and contract requirements can all affect how an insurer views your risk. If you are unsure whether something is relevant, ask before submitting an application or accepting a renewal.

Accurate disclosure does not guarantee that cover will be offered or that a claim will be paid. Insurer decisions depend on policy wording, underwriting criteria and the circumstances of any claim. However, careful and honest information can reduce avoidable disputes and help your policy better reflect the business you actually operate.
