Dry Hire vs Wet Hire Insurance: Machine and Operator Damage

Key takeaways

• Dry hire supplies the machine; wet hire supplies the machine with an operator or operating service.
• Machine damage, operator error and third-party damage can engage different policy sections.
• The hire agreement changes contractual responsibility, but it does not guarantee insurance cover.
• Usage, site, attachments, transport and maintenance details belong in the submission.

Dry hire vs wet hire insurance comes down to who supplies the machine, who controls its operation and what the contract says if something is damaged. Adding an operator changes the activity from equipment supply alone to equipment plus a service.

That distinction matters, but it isn’t the whole answer. The machine policy, liability wording, motor treatment, workers compensation arrangements and hire contract all need to line up.

Safe Work Australia’s model plant risk code sets out how both the hirer and supplier can hold safety duties when plant is hired. It applies as adopted in each jurisdiction, and WHS duties are not identical across every state and territory. Those duties are separate from whether an insurance policy responds to damage.

What is the difference between dry hire and wet hire?

Dry hire generally means supplying plant or machinery without an operator. Wet hire generally means supplying the machine together with an operator or operating service.

Question	Dry hire	Wet hire
Who operates?	Hirer or its authorised worker	Owner’s employee or engaged operator
Core activity	Equipment supply	Equipment supply plus operation
Key evidence	Hirer controls, condition reports, authorised use	Operator competency, job scope, lift or work plan
Contract focus	Custody, return condition, permitted use	Service scope, supervision, site directions

Tank’s dry hire insurance guide covers the equipment-owner view. For excavators and related plant, the earthmoving and excavator insurance page adds activity-specific context.

Which cover may respond to machine damage?

The answer depends on who owns the machine, how it was being used, and the relevant insured damage section. A contract saying the hirer is responsible does not create cover where an exclusion or condition applies.

As a starting point, supplying an operator generally puts the supplier’s own liability cover in the frame for how the machine was used, while supplying the machine alone generally puts it into the hirer’s custody. Both are starting points only, and the wording, contract and exclusions decide the outcome.

Review:

• accidental damage and theft scope;
• whether the hirer carries hired-in plant cover, since a hirer’s liability policy will usually exclude property in their care, custody or control;
• whether the machine is at the owner’s premises, in transit or at a worksite;
• authorised operators and licence conditions;
• underground, lifting, demolition or other declared uses;
• attachments and accessories;
• mechanical breakdown and wear exclusions; and
• excesses, security conditions and recovery rights.

The hire firm’s interest in machinery away from its possession can also have a separate legal dimension. The Australian Government’s PPSR hire and rental guidance explains when registration may help protect an interest in hired equipment. PPSR registration is not insurance, and insurance is not a substitute for a valid security interest.

How can operator error change the claim pathway?

Operator involvement can add allegations about how the machine was used, not merely what happened to it. The first task is to separate damage to the hired machine from damage to someone else’s property or injury to another person.

Use this incident map:

• Damage to the machine: inspect the material damage or plant wording.
• Damage to third-party property: inspect public liability, care-custody-control and contractual liability terms. Where the machine is registered or road-going, check how the liability policy treats it, because registered plant is often carved out of public liability and picked up under a motor or plant liability section.
• Injury to the operator: consider the relevant workers compensation and workplace arrangements.
• Injury to another person: consider liability and the parties’ site duties.
• Lost hire income: inspect any agreed financial-loss or business interruption section and its trigger.

For broader liability mechanics, Tank’s public liability insurance guide explains why legal liability and policy response are related but different questions.

Where do the two activities blur?

Inside a single business. A machine can go out bare one day and go out with an operator the next. The label on the invoice changes. Whether the policy follows is a separate question.

That’s the practical risk. A business that describes itself as a dry hire operation, and is underwritten on that basis, has a different exposure the moment it supplies someone to run the machine. The reverse applies too: an operator-supplied service that occasionally leaves plant on site unattended has a custody exposure the wet hire description doesn’t capture.

Two questions are worth asking:

• Over the last 12 months, was any machine supplied with a person to operate it? If yes, the wet hire exposure is live regardless of how the business describes itself.
• Does the insurer’s record of the activity match that answer? Where a proposal says dry hire only and the work is mixed, that can become a disclosure question long before it is ever a claims question. The duty of disclosure sits in the Insurance Contracts Act 1984.

Where the split is genuinely mixed, it belongs in the submission as a split, not as a single label.

Which details make the insurance review usable?

Start with a machine schedule and activity statement. Then add evidence for the handover, operation and return of each item.

Include machine type, value, serial number, attachments, road registration, radius of work, transport method, dry or wet hire split, maximum hire period, authorised users, maintenance, security, claims and contract templates. If the business also performs contracting work, Tank’s insurance for contractors page can help separate the exposures.

For wet hire, add operator licences, experience, employment status, job types and who directs the work at the site. Under the model WHS framework published by Safe Work Australia, certain plant work requires a high-risk work licence, issued and administered by the WHS regulator in each jurisdiction.

Frequently Asked Questions

Does dry hire insurance cover damage caused by the hirer?

It may, depending on the policy, contract, exclusions, excess and circumstances. Contractual responsibility alone doesn’t decide policy response.

Is wet hire automatically covered under a dry hire policy?

No assumption is safe. Wet hire adds operator and service exposures that need to be declared and accepted under the relevant sections.

Who insures the operator on a wet hire job?

Check the applicable workers compensation, employment, contract and liability arrangements. Operator employment alone does not determine the full insurance response.
