Diesel Supplier or Fuel Distributor? A Practical Australian Guide

A diesel supplier, a fuel distributor and a fuel wholesaler can all put ultra-low sulphur diesel on a docket. The sale behind the docket is a different job. Burn the fuel and you are buying a delivery into your tank. Sell it and you are buying wholesale into a retail or reseller network. Lift it yourself at a gantry and you are buying ex terminal, with the truck on your side of the ledger. The quote has to name which of those you bought.

Match the word to the litres and to the place they land. A farm needs a tanker that can finish the drop. A servo group needs grade under the forecourt and a wholesale cost that still makes sense when the board moves. A yard that runs a bowser and a local round needs two service levels. One blended rate usually hides which side is carrying the other. Start with the distributor and supply options that match the business you actually run, then make the schedule do the work.

Wholesaler, distributor, supplier

The wholesaler sells the gantry

A fuel wholesaler sells bulk product at a terminal. The buyer is usually a reseller, a distributor, a large retailer, or someone big enough to uplift. The offer is a terminal gate price or a formula off it, a grade, an allocation when product is tight, and a meter ticket at the load arm. Ex-gantry ends when the compartment is sealed. Delivered-into-tank ends when the receiving tank has the litres, ullage was respected, and someone authorised has signed. A gantry price with no truck only works when the uplift is already yours.

Published terminal gate prices are the daily wholesale prints for a tanker load of a named grade at a named terminal. Public prints in Australia generally include fuel excise and GST. Contract schedules sometimes quote a TGP exclusive of GST, or a benchmark that sits beside the public figure. Line up terminal, grade, day, timestamp and tax treatment before you compare two differentials. A 1.5 cent gap is noise if one number still carries GST. Terminals in the same city can print different TGPs on the same morning. Name the terminal. Perth diesel can mean more than one gantry.

The distributor runs a territory

A fuel distributor buys or lifts wholesale product and places it into a patch. Customers are fuel retailers, independent servos, card outlets, other resellers and, on many regional books, end users as well. The distributor owns or contracts the trucks, may hold depot stock, extends credit into the network, and is who a site rings when a long weekend is about to empty a diesel tank. Grade that stays consistent, a price the retailer can explain, and a delivery rhythm that matches sales are the job.

A local distributor is that job at town scale: one yard, the town servo and the farms past it, and drivers who know which track takes a loaded tanker. Ask whether they lift from a terminal themselves, or a larger supplier fills the depot and they run the last kilometres. Title and the phone number on a bad day sit in different places.

The diesel supplier delivers to the burner

A diesel supplier's customer is the operator: mine, farm, vessel, civil crew, generator, transport yard. The promise is a known grade, in that tank, inside a window, at a landed price the account can reconcile. Plant stops when the fuel stops. Commercial diesel fails when the paper is only a cents-per-litre figure. The tank, the hose and the person who signs are the service. Fuel transport is what you feel when the load misses the window. Who employs the driver matters as much as the letterhead.

End-user supply is a site problem

Access, hose and ullage

Walk the pad before you argue the rate. A loaded tanker needs a surface that takes the axle weight, a turn it can finish, and a way out that avoids reversing past people. Overhead power, awnings, loader traffic and a fill point behind a bund are ordinary reasons a truck arrives and leaves empty. Mines add induction, an escort, a radio channel and a window that dies when blasting starts. Farms add a track that looked fine from a ute. Wharves add security and whoever controls the bunker point.

A hose reel of 30 to 40 metres covers a normal stand. A tank across a compound needs a longer hose or a different park, agreed in daylight. Camlocks and threads have to match. An adaptor built from the toolbox is a guess with a few thousand litres. Dip before the hose comes off. A 30,000 litre tank with an unknown heel and a high gauge will put diesel in the bund. Agree the maximum fill, watch the vent, and stop on the dip. Put a day contact and a night contact on the account.

Pumps, head and waiting time

Most site tanks take diesel from the truck pump, off the PTO or a small auxiliary pack. Flow depends on hose diameter, head, and the tank's own fill line. A bulk discharge often sits around 400 to 800 litres a minute, so 15,000 litres at 500 litres a minute is half an hour of pumping before the dip and the gate. If the allowance is 45 minutes and the escort takes 30, you pay waiting time on a clean drop. Say whether the clock starts at the gate or at hose-on. Gravity discharge needs head and a vent that can breathe. Petrol needs bonding and a tanker built for it. Stop if a valve or a blocked vent shuts the line. A deadheaded PTO pump kills seals.

A yard that can only accept a rigid needs a rigid rate. A B-double price for that job is a quote for the wrong truck. Onsite diesel delivery into a tank you control is the default for steady burn. A nozzle into machines is a separate task with its own exclusion zone. Mining fuel, agricultural supply and marine fuel can share a terminal lift and still need different gates, hoses and paperwork. Farms need a reorder point above the lead time from town. Vessels need a hose that reaches and a grade the engine is cleared to burn.

Retail station wholesale

A servo buys wholesale and sells retail. The distributor's job is the right grade in the tanks, on a rhythm that matches sales, at a cost the operator can tie to the terminal print. The retailer's job is the board, the shop, the bowsers and the wetstock. Wholesale into a retail tank is a compartment drop of diesel plus the petrol grades that site sells. Ullage moves every day. A highway long weekend, or a harvest Friday, is a different tank from last month's average. Load what the tanks will accept.

Board price, brand and equipment

The dealer lives in the gap between delivered wholesale cost and the board, after card fees, drive-offs and shrinkage. The terminal print moves most days. The board moves when volume and the competitor across the road allow it. Show reference price, differential, freight and rebate as separate lines. A volume rebate paid later, and only if you clear a band, misses this week's margin. Price support in a board war ends on a date. Budget on the unsubsidised number.

Branded supply is a second contract: image, exclusive supply, a multi-year term, and equipment that may belong to the brand. You pay a fee or accept a narrower supplier, and you expect the traffic to justify it. Unbranded supply leaves the board with you, and a switch still depends on who owns the tanks and bowsers. A dealer owns the stock and wears a wholesale fall until it sells. A commission agent is paid to operate. Fleet-card volume settles on a different cycle from the bulk account. Keep fuel card terms and wholesale fuel terms on separate schedules so a card fee never hides inside the diesel differential.

Wetstock and a long weekend

Dip every grade at the start of the day. Reconcile console sales to tank movement and record each delivery on the day it lands. A steady loss is a leak, a meter, theft, temperature, or a docket that misses the truck. Water-paste on a set day. Underground tanks take groundwater as seals age, and water in diesel is how microbial growth starts. Holiday cover needs a name: who authorises an emergency load, the surcharge, whether the gantry is open, and who wears it if the order was late or the truck was.

Local distributor partnerships

A local distributor often holds the customers and the roads. A partner holds terminal access, credit or extra trucks. Name the structure. Buy-sell: the local business takes title, wears the terminal move and keeps the margin. The partner owes product, a formula, a limit, and a gantry slot or a depot delivery. Cartage: the supplier keeps title and pays freight. Write down waiting time, a refused gate, and who talks to the customer. Consignment leaves the supplier's stock in the local tank, so agree the count, the price day, and shrinkage including temperature. Overflow trucks for harvest or a shutdown have to be inducted before that week.

Atlas Fuel does both jobs under separate agreements. End users in mining, marine, agriculture and general commercial work buy delivered diesel. Fuel retailers and local distributors buy supply into their own network. The company is Australian-owned and runs its own tankers, so dispatch and the driver sit in one business. That helps when a retail drop and a site tank are both short and someone has to nominate which ticket the truck runs. Write that priority down before harvest and shutdown land on the same week.

Lock territory, grades, who invoices, who owns depot stock, and who is protected when a terminal allocates. Lock insurance and the accreditation the road actually requires. In Western Australia that is WAHVA: fatigue, maintenance, and dimension and loading for operators who need it. Atlas Fuel's tanker fleet holds WAHVA for the WA work that accreditation covers. Queensland and Victoria runs sit under the Heavy Vehicle National Law, on the fatigue module the drivers are enrolled in. Exit terms sit beside the rate: notice, stock still in the tank, equipment, and whether orders already in motion complete.

ULSD, ULP and what is actually in the compartment

Most end-user volume in Australia is ultra-low sulphur diesel, 10 mg/kg sulphur, sold against the automotive diesel standard. Density at 15°C sits around 820 to 850 kg per cubic metre. Premium diesel with a detergent or lubricity additive, dosed at the rack or the depot, can also be in spec. It is a different product in the tank. Say which one you load, where the additive goes in, and what arrives if the dosing skid is offline. Unlabelled automotive diesel stays inside the standard's biodiesel limit. If a warranty assumes none, get the percentage in writing. Marine distillate needs its own grade on the docket.

Petrol is the retail half of the slate. Unleaded at 91 RON, premium at 95 and 98, and ethanol blend where the site sells it. A diesel-only supplier can still be the right counterparty for a mine. A distributor feeding servos has to carry every grade on that forecourt. The product range on the agreement should list fuels you can order this month from the gantry you actually use.

Heels, water and diesel bug

Multi-compartment tankers earn their keep on retail runs: diesel in one pot, petrol grades in the others, two or three sites, inside the mass limit, in a drop order the driver can physically do. Seals go on at the gantry and come off at the tank. Put the seal numbers on the docket. Switch loading, petrol on Tuesday and diesel on Wednesday in the same compartment, leaves a heel. A petrol heel pulls diesel flash point down quickly. Automotive diesel is checked against a minimum around 61.5°C, and a small petrol heel fails it. Diesel left in a petrol compartment upsets octane. Where a fleet switch-loads, the flushed litres belong on the docket.

Contamination also starts in the customer's tank. Water bottoms, sludge, an unknown previous product, and microbial growth at the fuel-water interface. Diesel bug feeds on water, blocks filters and pits steel. A clean delivery into that tank looks guilty by the afternoon. Paste for water before you drop. Water on the paste means deal with the tank before the next load feeds it. Warm above-ground tanks and tired underground tanks both grow this fault.

Filtration and a sample that can decide

Ask where the filter sits. A screen on the truck discharge stops scale and rag. Common-rail cleanliness is a site job: water separation on the tank inlet or the dispenser, elements changed on differential pressure. Ask for the housing and the micron rating. Elements that block every week are reporting free water. Biocide is a clean-up. Keeping water out, draining it, and turning the tank over is the storage plan.

On a disputed drop, take retained samples from the compartment and the tank, labelled with time, seal and ticket, before anyone adds more product. Appearance, density, water and flash point settle most cross-drops. A microbial test settles a slimy filter. Sulphur and distillation matter when the argument is specification rather than the wrong hose. Send the samples to a fuel testing laboratory under a method named in the contract, including who pays on a pass or a fail. Quarantine the tank if engines are already complaining.

Density, temperature and the billed litre

Diesel expands as it warms. Terminals and many wholesale deals correct volume to 15°C. A site dip is observed litres at the temperature of the steel. Treat about 0.08 per cent per degree away from 15°C as a field check. On 20,000 observed litres at 35°C that is about 320 litres, before meter tolerance or a heel. Proper settlement uses measured density and the volume-correction tables.

The schedule should say which litre is billed: observed litres off the truck meter, or litres corrected to 15°C. Use the same rule on a retail docket and a mine docket. Depot stock breaks when the gantry ticket is corrected, the yard dip is observed, and the temperature was never written down. Put it on the docket. Density well outside 820 to 850 kg per cubic metre is a reason to hold the load and sample.

Contract price and credit

Build the rate in lines

Name the terminal, the grade, and which print applies: order day, load day, delivery day or a weekly average, and the time it is taken. Add the differential, then freight by zone against a minimum drop, then waiting time, after-hours, cancellation, split delivery and remote access as their own lines. A short fixed price suits a shutdown or a harvest when the period is short, the volume is banded, and litres above the band have a price. Ask what volume a longer fixed number actually covers. Hold the landed figure against the terminal gate price for that grade and terminal. The gap is freight, service, credit and margin.

Credit is fuel already burned

Past cash on delivery, the litres are burned before the invoice is paid. Retention of title will not pull diesel back out of a dozer. Use a limit, a due date or a direct debit, and a stop-supply rule you will actually apply. Size it from burn: weekly litres times price times weeks of exposure, plus a spike and one extra load. A site on 30,000 litres a week and 30-day terms often has four to five weeks in the ledger. Near two dollars a litre delivered, excise in, that is around a quarter of a million dollars. Start new accounts on cash or seven days, then 14, then 30 if the history holds. Revisit the limit when a project or a harvest changes the burn.

A director guarantee fits a thin company. A bank guarantee fits a project account. PPSR is worth registering and still a weak net once the fuel is burned. Agree the day supply stops, and who can restart it, while the account is still polite. Weekly direct debit fits a servo because the stock turns. A monthly account on a busy forecourt is working capital. Price it.

Scheduling, minimums and after-hours drops

The gantry slot, the driver's hours and the ullage have to land on the same day. Metro orders are often next-day if they arrive in time to build compartments and book a load. Regional work needs a longer lead because it is kilometres. Retail orders should carry a dip and a sales expectation. End-user orders should carry a dip, a site contact and any induction constraint. Build the cut-off inside legal driving hours. Bottom loading through a metered arm, seals on after, is the normal lift, and petrol compartments bring vapour recovery with them. The load ticket should show grade, compartment, litres and temperature so the delivery docket can match it.

Minimum litres

The minimum that matters is the one on your schedule, in litres, by zone, with the fee below it. Metro delivered diesel often starts at a few thousand litres, because the fixed time of the trip dominates. Regional minimums rise with the kilometres. A full compartment is where the cost settles. Below the line, pay the short-drop fee or wait for a proper load. When the tank is smaller than the minimum, use a smaller truck, an agreed split, or a receiving tank. A small farm drop on a retail loop needs its own access time and its own price.

A gate that actually opens

Define after hours: a named hour, weekends, public holidays, and whether the gantry is loading. A surcharge with no clock is an open invoice. A servo about to run dry and a header about to stop both need a person, light on the fill point, and a dip. Atlas Fuel delivers on its own tankers into Western Australia, Queensland and Victoria, with the WA operation based at Kwinana Beach. In Western Australia that includes a 24/7 emergency path for Perth, Kwinana Beach and regional sites that can open the gate. For a Queensland or Victorian site, ask who answers, what volume can still move once the day trucks are committed, and what the night minimum is.

Dockets and fuel tax credits

The ATO fuel tax credit is the customer's claim, through the BAS, for fuel tax in the price of fuel used in eligible activities. Eligible off-road use in mining, agriculture, fishing and similar work is treated differently from diesel in a heavy vehicle on a public road. Heavy vehicles over 4.5 tonnes GVM on public roads generally draw a reduced credit, fuel tax less the road user charge. Light vehicles on public roads generally sit outside it. Rates index in February and August. Eligibility has edges, and this is the paperwork standard, not tax advice.

The docket has to be usable. Date, delivery point, grade, litres, supplier name and ABN, diesel and petrol split. A line that says "fuel" and mixes grades forces a guess. The docket proves the purchase. Apportionment, dozer versus light ute, stays with the business burning the fuel. A distributor's own claim is limited to fuel their eligible plant used. Litres sold through a bowser stay outside it. Keep the tickets.

What to lock before anyone signs

• Say whether you are burning fuel, selling fuel, or both, and which agreement covers which litres.
• Name who lifts at the terminal, who employs the driver, and who sends the invoice.
• List sites, tanks and bowsers, with ullage, hose reach, induction rules and who can sign.
• List grades you will order: ULSD, any additised diesel, and ULP grades on a forecourt.
• Write the terminal, the TGP rule, differential, freight zones, minimum drop and waiting-time clock.
• Write the credit limit, the terms, the security and the day supply stops.
• Say whether the deal is buy-sell, cartage or consignment, and who owns depot stock.
• Say who is protected when a terminal allocates, and who is shorted first.
• Record where filters sit, how seals are logged, and which laboratory test settles a dispute.
• Match the road: WAHVA for the WA work that needs it, HVNL fatigue arrangements in Queensland and Victoria.
• Name who answers after hours, the volume they can still move, and the surcharge.

Then talk to Atlas Fuel with one label on the enquiry: end user, retailer, or local distributor. Bring tank sizes, a recent week of litres, and the awkward site. The reply you want is a supply model and a schedule, read the same way you would choose a fuel supplier: litres, access and who owns the truck.

FAQs

Frequently Asked Questions

Straight answers to the questions site managers, fleet controllers and farm operators usually raise before locking in a fuel account.

What is the difference between a diesel supplier, a fuel distributor and a wholesaler?

A wholesaler sells bulk fuel at a terminal, usually ex gantry, to a buyer who will uplift or resell. A fuel distributor lifts or buys that product and supplies a territory: servos, resellers, card outlets, depots and sometimes end users. A diesel supplier sells to the business that burns the fuel and delivers into that tank. One company can do more than one. The quote should still say which role applies, who owns the truck, and where title passes.

We run a servo. What should the wholesale agreement cover?

The grades you sell, a price built from a named terminal gate price plus differential and freight, and deliveries based on dips. Add holiday and after-hours rules, a minimum, seal numbers, and who owns the tanks and bowsers. Branded sites carry image and exclusive-supply terms beside the fuel price. Dealers own the stock. Commission agents need to see who wears a wholesale move. A keen differential that misses a long weekend costs more than it saves.

We only burn diesel in plant. When is a local distributor the right call?

Buy from a diesel supplier who delivers to sites like yours when the volume and the access will take a tanker. Use a local distributor when that yard is how fuel reaches the district, or when they run end-user trucks and can show who employs the driver. Ask the minimum, the hose length, the unloading allowance and whether your induction allows the vehicle. Get waiting time in the rate before you compare cents.

How do we compare a TGP-plus price with a fixed price?

Match terminal, grade, day and tax treatment. Published TGPs generally include excise and GST, and a contract figure sometimes strips one of those. On TGP-plus, show differential, zone freight and fees against a minimum drop. A fixed price suits a short banded job. Ask what volume is covered and what the next litre costs above it. Compare both offers on the same access, and on whether the nominated truck can finish the drop.

What minimum and after-hours rules should be written down?

A minimum in litres by zone, and a short-drop fee under it. Metro figures are often a few thousand litres. Regional figures follow the kilometres. After hours needs a clock, a surcharge, a minimum, a contact who can open the gate, and confirmation the induction allows a night truck. Atlas Fuel's 24/7 emergency path covers Perth, Kwinana Beach and regional Western Australia where the site can take the vehicle. For Queensland and Victoria, confirm who answers and what volume can still move once the day fleet is committed.

Why do the dip and the invoice show different litres?

Diesel changes volume with temperature. Wholesale sales are often corrected to 15°C, while a dip reads observed litres. About 0.08 per cent per degree is a field check: 20,000 litres at 35°C is roughly 320 litres, before meter tolerance or a heel. The contract should name the billed litre, and the docket should show temperature. Proper settlement uses density and the correction tables.

What must the docket show for a fuel tax credit claim?

Date, delivery address, grade, litres, supplier name and ABN, with diesel and petrol split. Credits are a BAS claim for fuel tax on eligible use. Off-road use and heavy vehicles on public roads are treated differently, light vehicles on public roads generally sit outside the claim, and the rates index in February and August. The docket proves the purchase. You still apportion how the litres were used. A distributor's own claim covers fuel their eligible plant burned. Litres sold through a bowser stay outside it. Treat this as a paperwork standard. It is not tax advice.

A delivery or a tank looks contaminated. What happens next?

Stop. Paste for water, match the seals to the docket, and sample the compartment and the tank before more product goes in. Flash point catches petrol in diesel. Water and a microbial test catch bug growth. Density outside about 820 to 850 kg per cubic metre is a reason to hold the load. A truck screen and dispenser filtration do different work, so a blocked element can be the tank. Name the laboratory method in the contract, and leave the fuel quarantined until the result decides who pays.
