The fibre strike
Trenching for a new driveway, an excavator operator cuts a fibre optic cable that wasn't marked on the plans. The telco's repair bill lands on the contractor, and the policy's underground services terms decide the excess.

The short answer
What insurance does an earthmoving or civil contractor need in Australia?
Earthmoving and civil contractors in Australia usually carry public liability insurance, often $20 million, plant and equipment cover for machinery, commercial motor insurance for trucks and floats, and sometimes contract works. Damage to underground services is one of the most common and expensive claims, and infrastructure clients often set strict insurance requirements.

Common cover
What cover do earthmoving and civil contractors commonly use?
Most earthmoving and civil contractors build their insurance from a few separate policies. These are the ones that come up most, and why they matter for this kind of work.
Public liability
Covers damage to underground services, neighbouring property and third parties. Check excesses and sub-limits for underground services.
Plant and equipment
Excavators, loaders, rollers and attachments, whether owned, financed or hired in.
Commercial vehicles
Tippers, floats, water carts and utes.
Contract works
Civil contracts may require the works themselves to be insured.
When it gets harder
When does insurance get more complicated for earthmoving and civil contractors?
Digging is inherently risky, and civil clients are some of the most demanding when it comes to insurance.
Underground services
Striking a fibre cable, water main or gas line can lead to large repair and consequential costs. Policies often have higher excesses or conditions about dial-before-you-dig checks.
Infrastructure and government contracts
Road, rail, water and energy projects commonly ask for $20 million or more, specific wording and principals noted on policies.
Wet hire and dry hire
Hiring out machines with or without operators changes the risk. Policies need to reflect what you actually do.
Registered plant
Registered machines can fall between motor and liability cover while they're working. It is worth checking how your policies deal with that.
Illustrative examples
What does this look like in practice?
These are illustrative examples, not real clients, showing how the work changes the insurance.
The council contract
A small earthmoving business tenders for council drainage work. The tender requires $20 million liability, contract works and the council noted on policies. Their policies need to be checked against the tender before they submit.
Cost
What affects the cost of insurance for earthmoving and civil contractors?
These factors shape premiums for earthmoving and civil businesses.
| Factor | Impact | Why it matters |
|---|---|---|
| Type of civil work | Major | Residential site prep, roads, mining and infrastructure are rated very differently. |
| Plant fleet value | Major | The value and type of machines drives plant premiums. |
| Underground services exposure | Moderate | How much digging near services you do. |
| Turnover and operators | Moderate | More work and operators mean more exposure. |
| Claims history | Major | Service strikes and plant damage claims weigh heavily. |
Common questions
Questions earthmoving and civil contractors ask about insurance
Does public liability cover damage to underground services?
Usually, but often with a higher excess or a sub-limit, and sometimes with conditions such as checking service locations before digging. Check the wording carefully.
What liability limit do civil contracts ask for?
$20 million is common, and infrastructure, government and mining contracts can ask for more. The tender or contract documents set the requirement.
Is my excavator covered when I hire it out?
It depends on whether your policy covers dry or wet hire. Many plant policies need hire-out activities declared.
