The Road Transport Contractual Chain Order: What It Means for Civil Contractors Who Engage Cartage

A civil contractor prices a bulk earthworks job with 14,000 cubic metres going off site. The cartage is subcontracted to two local tipper operators on a rate per tonne, agreed six weeks before the job starts and fixed for the duration. That is how cartage has been let in this industry for as long as anyone can remember.

Since April 2026 that arrangement has sat inside a regulated contractual chain. When the trigger conditions are met, the law can require the party at the top of that chain to increase what it pays, whether or not the subcontract says anything about fuel, and whether or not the head contract lets the increase be passed up. Most civil contractors have never heard of the instrument that does it.

This guide explains what the order does, when it reaches a civil business, what it does not touch, and the commercial position worth taking before the next time diesel moves. It sits alongside our guide to fuel tax credits for civil contractors, which covers the money coming back to you from the ATO. This one is about money going out.

What the order is, and where it came from

The Fair Work Act now contains a set of provisions dealing with the road transport industry, sitting outside the employment relationship and reaching commercial contracts between businesses. One of the instruments the Fair Work Commission can make under them is a road transport contractual chain order: a binding instrument that regulates the terms on which parties in a chain of contracts for road transport services deal with each other.

The first one ever made was about fuel. Following the 2026 fuel shock, the Transport Workers’ Union and the Australian Road Transport Industrial Organisation applied jointly for an order requiring fuel cost increases to be passed down to the operators actually buying the diesel. The Commission made the Road Transport Contractual Chain Order — Fuel Cost Recovery — 2026 on 20 April 2026, commencing the following day.

The policy problem it addresses is a familiar one in civil construction too. When an input cost moves sharply, the party with the least contractual power absorbs it. In road transport that is the owner-driver and the small fleet operator, who buys the fuel, holds a fixed rate, and has no mechanism to recover the difference. The order compels the recovery rather than leaving it to negotiation.

Three features of it are unusual enough to be worth stating plainly before anything else:

• It operates on commercial contracts between businesses. This is not industrial law reaching your employees. It reaches contracts you have with other companies and with contractors who are not your workers.
• It can override the bargain. A fixed rate agreed in writing is not a defence. Where the order applies, the obligation to adjust exists independently of what the contract says.
• It switches itself on and off. The obligation is tied to a published diesel price. It is currently dormant. It did not need anyone’s agreement to become dormant and will not need anyone’s agreement to revive.

Why a civil contractor is in a road transport chain

The instinctive reaction is that this is a trucking matter. It is not, for the same reason chain of responsibility is not a trucking matter: the law defines the chain by function, not by industry label. If your business engages someone to carry goods by road under a services contract, you are a party to a road transport contractual chain regardless of what your ABN says you do.

A civil business typically sits in one of these positions:

Arrangement	Typical civil example	Likely position
You engage cartage directly	Tipper operators carting spoil off a subdivision, or importing select fill	You are a party to a road transport services contract and may be the first party in the chain
You engage a haulage company that subcontracts	A cartage firm that hires in owner-drivers at peak	You are upstream of a further contract; the firm below you is also bound
You are engaged by a head contractor whose scope includes cartage	Tier 1 lets a haulage package to you and you sublet it	You are in the middle of the chain — bound downwards, dependent upwards
You buy materials delivered	Quarry product supplied at a delivered rate	Usually a supply contract, not a road transport services contract — see below
You cart with your own trucks and your own employees	An in-house tipper fleet	No services contract for that work, so no chain for it

The fourth row is the one that catches people out in both directions. A delivered rate from a quarry is normally a contract for the supply of goods with carriage included, not a contract for road transport services — the distinction is covered in our guide to materials supply agreements and quarry arrangements. But where the same quarry invoices you separately for cartage, or where you engage the trucks yourself and buy the product ex-bin, the characterisation changes. It turns on the substance of the arrangement, not on the invoice layout.

The line that decides everything: road transport work

This is the single most important thing for a civil contractor to understand, and it is good news.

The order reaches road transport work. It does not reach fuel burnt by plant on site. The diesel in an excavator, a dozer, a roller, a water cart working within the site boundary, a crusher or a generator is outside it entirely. That fuel is a construction input, priced in your rates and — where it is used off public roads — the subject of a fuel tax credit at the full rate rather than the reduced on-road rate.

So on a typical civil job the order divides your diesel bill in two:

Fuel	Inside the order?	What governs your exposure
Subcontracted tippers carting spoil or import on public roads	Capable of being inside	The order, plus whatever your subcontract says
Subcontracted float moving your own plant between sites	Capable of being inside	The order, plus the float agreement
Your own trucks driven by your own employees	No — no services contract	Your cost base and your award or agreement obligations
Excavators, dozers, rollers, graders on site	No	Your rates, your escalation clause, your fuel tax credit claim
Water carts and dumpers operating within the site	No	As above
Hired-in plant with operator, working on site	No — plant hire, not road transport	Your plant hire agreement

The practical consequence is that a civil contractor’s exposure is much narrower than the headlines suggest, and is concentrated in exactly one place: subcontracted cartage and float movements. On a job with no external haulage, the order does nothing. On a bulk earthworks or quarry-import job where cartage is 25 per cent of the contract value and all of it is sublet, it matters a great deal.

One further exclusion is worth noting because it shows how the boundary is drawn: cash-in-transit services sit outside the order despite plainly being road transport. Being in an industry is not the test. Being party to a contract for the relevant services is.

Primary and secondary parties

The order distinguishes between the party at the top of a chain and the parties further down it.

• The primary party is a party to the first contract or arrangement in the road transport contractual chain — the business whose need for transport creates the chain in the first place.
• A secondary party is a party to a later contract in the same chain — the firm that takes a haulage package and sublets part of it, and everyone below.
• A regulated road transport contractor is the contractor performing the work under a services contract in that chain. This includes owner-drivers and small fleet operators who are not employees of anybody.
• Employee-like workers performing road transport work through a digital labour platform are also within the protections, which is how the provisions reach gig-model delivery work.

Where a civil contractor lands depends on the job. On a council contract where you engage the tippers yourself, you will usually be the primary party for that chain. On a Tier 1 subcontract where haulage is inside your scope and you sublet it, you are a secondary party — bound downward, and dependent on the party above you to fund the increase. That asymmetry is the commercial heart of the problem and is dealt with in §09.

What the obligation actually requires

Stripped to its essentials, the operative clause requires the paying party to adjust the amount it pays so that the contractor recovers the increase in fuel costs, and to do so on a short cycle — within each fortnight, or twice per calendar month. It is not an annual reconciliation and not a claim to be made at the end of the job.

Importantly, the order does not prescribe one mechanism. Compliance can be achieved through any of these:

• Adjusting the rate itself — repricing the per-tonne or per-hour rate on the cycle.
• Adjusting a fuel component within the rate — where the rate is built up with an identified fuel element.
• A fuel levy or increment — a separate line added to invoices, which is how most of the transport industry already does it.
• Direct reimbursement or a cost offset — reimbursing the measured difference.
• An existing rise and fall or benchmarking formula that already achieves fuel cost recovery.

That last point is the one to build your position around. An existing mechanism that genuinely recovers fuel cost movement can satisfy the order. A contractor who has already written a workable fuel adjustment into its cartage subcontracts is in a materially better position than one relying on silence, because the mechanism is known, budgeted, and administratively routine rather than improvised under pressure.

The trigger, and what “dormant” means

The obligation is not permanently on. It is tied to a published price: the weekly average national terminal gate price for diesel, as reported in the Australian Institute of Petroleum’s weekly diesel price report. When that measure sits below $2.00 per litre, the fuel cost recovery obligations cease to apply.

That is exactly what happened. Diesel fell back through the threshold during June 2026 and the Commission issued a statement confirming the obligations had become dormant. The order itself was not revoked and remains in force. Dormant is not dead: the obligations sit there waiting for the price measure to move back above the threshold.

Two things follow, and both are easy to get wrong.

• The trigger is the terminal gate price, not the price on the bowser. Terminal gate price is the wholesale price at the fuel terminal. It moves before and differently from retail pump prices, and it is the only measure that matters for this instrument. A contractor watching retail diesel to work out whether the order is live is watching the wrong number.
• Reactivation does not require a decision by anybody. No application, no hearing, no notice to you. If the published measure moves, the obligation moves with it. That is why the mechanism belongs in your subcontracts now, while it is quiet, rather than in an argument later.

The Commission has been reviewing the order on a short cycle since it was made — an engagement conference in May 2026, a first formal review hearing later that month, proposed amendments released at the end of May, and quarterly reviews thereafter. Among the amendments proposed is a change to the cessation mechanism so that obligations only cease after the price sits below the threshold for four consecutive weeks, which would make the on-off switching less abrupt. Because the instrument is under active review, the operative text is the thing to check before acting, not a summary of it — including this one.

Where it meets your own rise and fall clause

Civil contractors already have a vocabulary for this problem. Our guide to rise and fall and cost escalation in civil contracts covers how escalation clauses are built, which indices are used and where they fail. The order interacts with that machinery in three ways worth understanding.

Situation	What the order does	What to do about it
Your cartage subcontract has a fuel levy tied to a published index	Likely satisfies the obligation, if it genuinely recovers the increase	Check the index and the frequency. A quarterly adjustment does not sit comfortably with a fortnightly obligation
Your cartage subcontract is silent on fuel	The obligation exists anyway when triggered	Add a mechanism. Silence gives you no control over how the adjustment is calculated
Your head contract has no escalation at all	Nothing — the order does not create an entitlement upward for you	Price the exposure, or seek an escalation provision at tender stage
Your head contract escalates on a general construction index	Nothing specific to fuel	Test whether the index actually tracks diesel. Most do not, or do so with a lag

The mismatch in the last two rows is the exposure. A general index moves slowly and broadly; a fuel obligation moves fortnightly and sharply. Where your downstream obligation is fast and specific and your upstream recovery is slow and general, the gap is real money and it is yours.

Four things it is not

Misunderstandings about this instrument are common and expensive in both directions. Four in particular are worth naming.

• It is not a fuel tax credit. Fuel tax credits are a rebate from the ATO on fuel your business acquires and uses. The order is an obligation to pay another business more. They are unrelated, and a contractor can be affected by both in the same quarter. The credit side is covered in full in our guide to fuel tax credits for civil contractors.
• It is not a general construction escalation right. It says nothing about steel, cement, bitumen, labour or the diesel in your own plant. A contractor who reads it as authority for a broad escalation claim on a fixed-price head contract will be disappointed.
• It is not automatically passed up the chain. The obligation runs downward. Whether you can recover the increase from your principal depends entirely on your head contract. Nothing in the order creates that right.
• It is not chain of responsibility. Different Act, different regulator, different duties. Chain of responsibility is heavy vehicle safety law administered by the NHVR and concerns mass, dimension, loading, speed and fatigue. This is workplace relations law administered by the Fair Work Commission and concerns what you pay. Both use the word “chain”, and confusing them leads a contractor to look for the answer in the wrong place. The safety-side changes are covered in our guide to the 2026 Heavy Vehicle National Law changes.

The squeeze: owing down without recovering up

Every regulated pass-through creates a squeeze somewhere, and in construction it lands on the party in the middle. The structure is worth setting out because it is the thing a civil SME should actually be managing.

A subcontractor holds a fixed lump sum from a Tier 1 for a package that includes 8,000 tonnes of cartage. It sublets the cartage on a fixed rate per tonne. Diesel rises above the threshold and the obligation activates. The subcontractor must now increase what it pays the tipper operators. Its own contract with the Tier 1 has no fuel escalation, because the Tier 1’s contract with the principal has none either. The increase is absorbed at the point in the chain least able to carry it.

Four responses are available, in ascending order of effectiveness:

• Price a contingency. Crude, and it makes you dearer than a competitor who has not thought about it. Better than nothing, but it loses work.
• Carry your own cartage. Owning the trucks removes the services contract and therefore the chain for that work. It also introduces a fleet, drivers, accreditation, maintenance and utilisation risk — a large decision to make for this reason alone.
• Qualify the tender. A short, specific qualification that cartage rates are subject to statutory fuel cost recovery is legitimate, easy to explain, and much more likely to survive evaluation than a general escalation qualification. Note that qualifications carry their own risk in a compliance-scored tender — see non-conforming and alternative tenders.
• Get a matching mechanism into the head contract. The most effective and the hardest. It is easiest at tender stage, when the question is a clarification rather than a variation, and it is helped considerably by being able to point at a specific instrument rather than asking for escalation in general.

That last point deserves emphasis because it changes the conversation. “We would like escalation on fuel” is a commercial ask that a principal can simply decline. “Cartage in this scope sits in a regulated contractual chain and we are required to adjust rates when the published diesel measure moves” is a description of a legal obligation, and it invites a mechanism rather than a refusal. Raise it in the clarification window, not after award.

What to put in a cartage subcontract now

The order can operate whether or not your subcontract addresses fuel. That is precisely why it should. A contract that is silent hands the calculation, the timing and the evidentiary standard to whoever argues hardest. A contract with a mechanism keeps them where you can administer them.

A workable clause covers six things:

Element	What it should say	Why
The index	Name the published measure and the source, and say what happens if it stops being published	Removes the argument about which number applies
The baseline	The index value at the date the rate was set, stated as a number in the contract	Without a baseline there is nothing to measure the increase against
The fuel component	The proportion of the rate attributable to fuel, agreed up front	Adjusting the whole rate by the fuel movement over-compensates; this is the most commonly botched element
The cycle	The adjustment frequency and the date it is applied from	The obligation contemplates a short cycle; a quarterly clause may not satisfy it
Symmetry	That the mechanism operates down as well as up	A one-way clause is a rate rise with a trigger, not a cost recovery mechanism
Substantiation	What the operator provides and by when	Makes the adjustment administrable rather than negotiable

Two drafting cautions. First, do not import a fuel clause from a head contract without checking the index actually tracks diesel — general construction indices routinely do not. Second, be careful with a clause that only operates “where required by law”. It sounds prudent and it is nearly useless: it leaves the calculation undefined at the exact moment you need it defined, and it invites an argument about whether the trigger has been met.

Substantiation: what to ask for, what to keep

An obligation to recover an increase implies an increase capable of being measured. Where a claim comes across your desk, the questions to ask are ordinary contract administration questions, and they are not unreasonable to put:

• Which work does the claim relate to, and is that work road transport work under a services contract with you?
• What baseline is the increase measured from, and does it match the rate actually agreed?
• What fuel component of the rate is being escalated, and how was it derived?
• What period does it cover, and does that period align with the cycle in the order or the contract?
• Has any part of this already been recovered through another mechanism — a levy, a rate review, or a variation?
• Does the claim separate road transport work from any on-site plant work performed under the same engagement?

That last question matters on civil jobs more than anywhere else, because the same operator often does both. A contractor supplying tippers that cart off site and also tracks material around the site with the same fleet is performing work on both sides of the line. Splitting it is the claimant’s job, but only if somebody asks.

On the record-keeping side, keep the rate build-up showing the fuel component, the index value at the date of agreement, every adjustment applied with its calculation, and any correspondence in which relief was agreed. Agreeing to defer or reduce an adjustment without documenting it is how a party accidentally waives a position it thought it had preserved. This is the same discipline our guide to contract administration for civil SMEs applies to notices and variations, and it works here for the same reason.

Disputes and enforcement

Contravening the order is a civil remedy provision under the Fair Work Act. That places it in a different enforcement world from an ordinary contract breach: it is not a debt to be argued about commercially and settled at the end of the job, and the Fair Work Ombudsman has a role in the framework it sits within.

Disputes about the operation of the order can be referred to the Fair Work Commission. For a civil contractor used to security of payment and construction dispute resolution, that is an unfamiliar forum with unfamiliar procedure, and it is not a place to arrive unadvised. The practical implication is not that you should fear it. It is that this exposure should never get that far, because the mechanism should have been agreed at contract formation.

A proportionate position for a civil SME

The obligations are dormant. Nothing needs to be paid today. The correct response is neither to ignore the instrument nor to build a compliance program around it, but to make three cheap changes while there is no pressure.

Timeframe	Action
This month	List every current engagement where you pay another business to carry something by road. That list is your exposure, and for most civil SMEs it is short
This month	Read the fuel provisions in those subcontracts. Sort them into “has a workable mechanism”, “has a mechanism that would not satisfy a fortnightly obligation”, and “silent”
Next contract	Put a six-element fuel adjustment clause into your standard cartage subcontract, covering index, baseline, fuel component, cycle, symmetry and substantiation
Next tender	Where cartage is a material part of the scope, ask the escalation question in the clarification window rather than pricing a blind contingency
Quarterly	Check the status of the order. It is under active review and the trigger is a published number, so this is a five-minute task, not a project

For a contractor with no external cartage at all, the honest answer is that this does not currently affect you — and the right time to remember it is the first job where you sublet haulage.

Checklist

• Do you know which of your current engagements are contracts for road transport services rather than supply or plant hire?
• Have you separated fuel used in road transport from fuel used by plant on site, in both your pricing and your records?
• Does your standard cartage subcontract name an index, a baseline value and a fuel component?
• Does the adjustment cycle in that subcontract match a fortnightly or twice-monthly obligation?
• Does the mechanism operate downward as well as upward?
• On your current jobs, is there any fuel escalation in the head contract at all — and does it track diesel?
• Where cartage is a material part of a scope you are bidding, have you raised escalation in the clarification window?
• Do you know where to find the weekly national terminal gate price for diesel, and do you know it is not the pump price?
• If an adjustment claim arrived tomorrow, could you check it against an agreed baseline within an hour?
• Have you recorded any relief or deferral you agreed to, rather than settling it in a phone call?
• Does whoever lets your subcontracts know this instrument exists?

The short version

• The Road Transport Contractual Chain Order — Fuel Cost Recovery — 2026 commenced on 21 April 2026 and is the first instrument of its kind made by the Fair Work Commission.
• It reaches commercial contracts for road transport services. Construction businesses that engage cartage are among the parties it can bind.
• Fuel burnt by plant on site is outside it entirely. A civil contractor’s exposure is concentrated in subcontracted cartage and float movements.
• When triggered, the paying party must adjust rates on a short cycle — within each fortnight or twice monthly — so the operator recovers the fuel increase.
• An existing rise and fall or fuel levy mechanism that genuinely achieves recovery can satisfy it. Silence does not stop the obligation; it just removes your control over how it is calculated.
• The trigger is the weekly average national terminal gate price for diesel, not the retail pump price.
• Obligations went dormant during June 2026 when that measure fell below $2.00 per litre. The order was not revoked and can reactivate without notice to anyone.
• The obligation runs downward only. Nothing in it gives you a right to recover from your principal — that has to come from your head contract.
• It is not chain of responsibility, not a fuel tax credit, and not a general escalation right.
• The cheap move, available now while it is quiet, is a six-element fuel clause in your standard cartage subcontract: index, baseline, fuel component, cycle, symmetry, substantiation.
