Farm Diesel Delivery in Australia: What Suppliers Need to Get Right

Farm diesel delivery fails in ways a factory yard never sees. The tank looked comfortable on Monday. The semi cannot turn at the shed. Harvest ran nine days past the litres nominated in August, and the contractor's chaser was never in that number. A flat fortnightly drop misses all three. The season sets the burn. The property sets the truck.

This is for growers, farm managers and contractors who buy agriculture fuel for the machines that use the volume. Utes and one-off cans stay on a fuel card or the town bowser. The header, the sprayer, the air seeder, the auger and the bore pump belong on the farm tank. Mix those jobs and you either waste a truck or park a crew in town while a paddock is ready.

What the season does to the litres

Most of the year a farm tank declines slowly. Then it does not. A monthly average hides the weeks that empty it. Air seeders, boom sprayers, headers, chaser bins, field bins and the trucks between them can finish a volume that looked fine a fortnight earlier. Book farm diesel delivery against that shape, with a buffer, and ignore June's quiet dip when you set the harvest line.

Seeding is a hard start

Seeding is a short window tied to the break and the forecast. Tractors and air carts run long days, and plant that sat all summer comes out dirty. Place the opening load before the district is on the same week. A two-day slip is manageable if the tank was filled to a working level. An empty tank on the second morning is a lost paddock.

Spray pulses, harvest runs long

Spray programs pulse: knockdown, in-crop, desiccation. Litres are high while the boom is out and quiet when it is not. A drop every second Thursday misses the spraying week. Name those weeks. Harvest shifts paddocks, waits on moisture and brings contractors who were absent from the August litres. Nominate the season, set a reorder trigger, and keep a phone path for the week the program runs long.

The calendar is regional. Winter cropping in the west and south seeds off the autumn break and harvests from spring into summer. Cotton, sugar, summer crops and station work run to another clock, and a wet-season road can close before the tank does. Name the district and the hard weeks, and update them when the season moves. Once the district starts together, the quiet-month supplier is fully committed.

On-farm tanks that can take a real drop

Know working capacity, safe fill and the coupling before you ask for a price. Nameplate volume is the steel, not what you can receive. A water bottom, a dip point that lies, or a vent that weeps at three-quarter full will refuse the drop written on the quote. Leave ullage. Diesel delivered cool expands once the day heats the steel, and a harvest fill metered hot sits higher in the afternoon than it will at dawn. Storage should meet AS 1940, with a bund that can hold a spill, especially near drains, creeks and sheds that already hold other fuels.

Label the fill point

A lot of farm tanks take a camlock. Check the size, the gasket and whether the fitting lives in the weather. Dry-break couplings drip less when they come apart, if the tanker is carrying the match. An adapter from a drawer is how a spill starts beside a crop. Where petrol, waste oil or an AdBlue-type product shares the shed, label the diesel point, read the tank name and point at the stencil before the meter starts.

Shut the bund drain and empty rainwater before the truck is due. A bund full of water has no room for diesel, and an earth wall around an older tank fails the same way after a storm. Half-buried tanks hide a bad fill, so dip them. Say which paddock and station tanks a road tanker can reach, and which ones you will feed with your own nurse tank.

The tank that sat all summer

A tank idle from January to the autumn break collects water and dust as temperatures swing and hatches sit open. The first big seeding drop stirs that bottom. Dip with water-finding paste before you order the opening load. If the paste shows free water, or a bottom sample is hazy, sour or dirty, fix the tank before fresh diesel buries it. Fuel taken off a low outlet can send that water into a common-rail engine.

Soft tracks, gates and wet weather

Bitumen to the mailbox is the start of the trip. Delivery is the gate, the track, the soft corner, the culvert, the powerline and the pad beside the tank. If a semi cannot do it, say so before harvest week. A rigid or a smaller drop may be the honest tool. Farm diesel suppliers who only take a street address will send the truck that suits their run, then discover the property.

Two notes: dry and wet

Write the route from the public road twice. The dry note names the gate, the track, where to turn and where to stay off. The wet note is allowed to say do not come. Black soil after rain, sand that shears on a turn, a headland, a melon-hole flat, a creek crossing: duals and trailer axles find the soft patch a ute missed. A tanker on its belly is a spill risk, a recovery bill and fatigue hours taken off someone else's farm. If you would not take a loaded truck down that lane, do not order one.

SWER lines, shed feeders, tree limbs and a fill under a roof sit inside a tanker's envelope. Ask the travelling height and measure the path the truck will drive, including a hose lifted to a high fill. Culverts and old creek crossings that carry a ute can fail under a drive axle. Name who will spot a long reverse, and have them there.

The truck the ground will give back

Match the vehicle to the gate, the swing and the ullage. A small rigid goes through a farm gate a trailer will not. The rate per litre looks dearer because the trip cost sits on fewer litres, and it is still the cheaper day if the semi has to be pulled out. A larger tanker earns its keep when the home tank can take a proper drop and the pad will carry the axle out as well as in. Check the climb out, loaded.

In the wet, fill the home tank while the track is one you trust, and refuel the paddock from a nurse tank your crew can handle. Leave the road tanker out of the crop. Mats, a spotter or a wait for the surface to dry are decisions made before loading. Tell dispatch which note applies that morning. A bogged trip is often billable.

• Gate width, turning room, and the truck class those two will accept.
• A dry-weather track note and a wet-weather note, including the climb out.
• Lowest overhead clearance on the real path, including a raised hose.
• Culverts, creek crossings and any weight limit a ute hides.
• Park-up, hose reach, and who spots a reverse.
• Dogs, irrigation gear, locks, and a mobile number that works in the paddock.

Pumps, hose length, density and the morning dip

The unload is a product pump off the PTO or a hydraulic drive, a meter in the discharge, and a hose reel. On a farm the reel is often the limit, because the truck parks short of the tank. Twenty metres of hose and forty are different jobs, and a high fill point cuts the flow again. The rate on the day is the slowest of the pump, the hose, the lift and the vent. If the vent whistles or weeps, stop. Hold the pump speed the driver was trained to. Extra revs on the PTO do not make a blocked vent larger.

Match the coupling before the truck leaves the yard. The driver stays at the valve for the transfer. Dip first and write the safe fill down. Cover stormwater pits and shed drains near the joint, and keep a spill kit at the connection. Stop the pump, contain what you can, and keep it out of drains and crop. The driver owns the transfer while the pump is running. The farm owns the pad, the tank and the decision to receive.

Mass, temperature and a dip that will not match

Diesel is dense. At 15 degrees Celsius it commonly sits around 0.82 to 0.85 kilograms a litre, depending on the batch. A tanker remembered as full of a lighter product can hit its mass limit before those compartments are full of diesel. The water capacity painted on a barrel is not the diesel that truck can deliver on your route. Ask for deliverable litres under the mass limit that applies. Warmer diesel is lighter per litre, so the same mass is more litres. Colder diesel runs the other way. A seeding order built on a summer compartment story can come up short on a cold morning while the driver stays legal on the scales.

Volume moves with temperature, in the order of 0.08 percent for each degree Celsius, against a 15 degree reference. An 18,000 litre drop metered near 36 degrees and dipped next morning near 14 degrees can look short by roughly 320 litres, with the product still in the tank. Measure product temperature, not the air. The contract has to say whether the sale is observed meter litres or litres corrected to 15 degrees. Dip with the driver watching and write both figures plus the product temperature. The dip checks the ticket. It is not a second certified meter.

Contractors, nurse tanks and the bowser key

A two-header crew plus a chaser can add a large slice of daily burn the week they arrive. Decide before they unload who may use the bowser, how it is recorded, and which machines bring their own diesel. The supplier fills what you order. They cannot reconstruct a handshake from October.

A bowser meter with a code for each crew, or a dip book signed at the shift, works if someone uses it. Put the contractor litres in the seasonal nomination, or keep those machines on their own fuel. Refuse a visitor's drum tipped into your tank to be helpful. Their water and their diesel bug become the header's problem, and the docket no longer describes the vessel.

Onward carting is your system

Carting from the home tank to the paddock in a nurse tank or trailer is yours: the tank, the fittings, the tie-downs and the spill kit have to be legal for the way you use them. The delivery into approved storage ends the supplier's job. A split drop between two farms works only when both can receive that day, each tank gets the grade it should hold, and each docket shows its own litres.

Water, diesel bug and the filter that shut

A header or sprayer that coughs after a fill is a paddock stop. Stop issuing, compare the time with the last docket, then look at the tank. Water, dirt, the wrong product and a failing vessel are the usual causes. Diesel bug lives at the fuel-water interface: slime, a sour smell, filters blocking in days. A tank that older engines tolerated can punish a common-rail machine. The injectors got tighter. The housekeeping did not keep up.

One sick machine points at that machine. Filters blocking across the fleet after a delivery point at the tank. Quarantine a foul tank instead of chasing it with another load. Drain water where the design allows it. A tank with no water point needs a drainable vessel, or a polish through filters, before the next program. Keep hatches closed in harvest dust, and keep bund water out of the diesel.

What filtration is for

A filter on the tanker discharge, where you have specified one, protects the storage from the hose on the day. The bowser filter protects the machines from fuel that has been sitting. Fit the micron the header and the sprayer call for, and fit a water-separating element that is in date. A water-block that has shut is doing its job. Pulling it and pumping on sends water to the injectors. Machine filters are the last line, not the farm's fuel system. If the fuel smells wrong, the paste shows water, or several machines misbehave after a top-up, stop and use fuel testing. Take a bottom sample and a bowser-line sample if plant is already down. They answer different questions.

Beside a crop, a creek or a shed drain, a weeping camlock is a spill, not a stain on the gravel. Atlas Fuel holds ISO 14001. That system should make stop, contain and report the habit when a coupling fails. The certificate does not empty a bund full of rain. Drain it before the truck is booked, and keep the drain shut while product is moving.

A reorder point the depot can load

Set the reorder on peak daily burn. Litres still in the tank when you order should cover the lead time you have actually seen, plus the slip you already know. A Thursday order that became Saturday twice last harvest is a one-day slip, and it belongs in the sum. Ullage at that moment still has to accept the minimum drop for the vehicle and the district. If it does not, you will order late, pay a short-drop fee, or need another tank before the program.

Use your own sheets. About 7,500 litres a day, a two-day lead and a one-day slip means ordering while roughly 22,500 litres remain. On a 60,000 litre safe fill, the room left takes a proper drop. On a 28,000 litre safe fill, the same trigger leaves about 5,500 litres of room, and a 12,000 litre minimum will not fit. Seeding needs its own line. A program at 3,500 litres a day should not inherit the harvest trigger left in someone's phone.

Cut-off, fatigue and the road to the farm

Confirm the litres before the truck is under the gantry. A late cut can fall under the minimum. A late increase can exceed the mass the route allows, or the ullage left when the truck arrives. Give a window even if it moves. Regional lead time is not the metro figure. Name the district. Shire roads and the driver's hours sit inside the schedule.

On country roads the tanker is a heavy vehicle before it is a bowser. In Western Australia the Atlas Fuel fleet holds Western Australian Heavy Vehicle Accreditation. WAHVA covers fatigue, maintenance, and dimension and loading for the WA work that scheme applies to. It puts a maintained truck on the shire road. It does not firm a black-soil lane or narrow a trailer to the gate. Queensland and Victoria runs sit under the Heavy Vehicle National Law, on the fatigue arrangements those drivers use. If the combination is too big for the entrance, ask for a vehicle that fits.

The after-hours call during harvest

Use the night path when the tank will not make the next cutting day. Call with the dip, the tank, the machine that stops, who will meet the truck, and whether the track is the dry note or the wet one. Atlas Fuel provides 24/7 emergency onsite diesel across Perth, Kwinana Beach and regional Western Australia when the property can take the truck. Night still needs light and a track you would drive loaded. Queensland and Victoria farm supply is planned. Ask what can still move once the day trucks are committed, and what the night minimum is. If the gate stays shut after dark, reorder so the tank reaches daylight.

Price, minimums and a quote you can check

Compare the delivered litre with a terminal gate price you can look up, plus a stated differential, plus freight for the district. Name the terminal the truck lifts from. A gate price in one capital is a different market from another capital on the same day. On the wholesale series buyers use, that figure includes excise and excludes GST, freight, the supplier's margin, waiting and any after-hours fee. Ask which week, what differential, what freight, and whether GST is inside the cent. Compare ex GST. A single delivered number cannot be checked the week the terminal jumps.

A fixed figure for a seeding or harvest campaign suits a farm that wants the number to sit still. Ask whether freight is inside it, who wears a sharp terminal move, and what happens if you take fewer litres than you nominated. Minimum drop, free waiting time, the rate after that, public holidays and after-hours belong on their own lines. Waiting because nobody was at the gate is a farm cost. Put the receiving person on the order.

Minimums that do not fit the tank

A minimum exists because the truck costs money on a short drop and on a full load. Ask the figure for your address and for the vehicle the track can take. Long dead-running sits higher because of the kilometres. A minimum the tank cannot hold means a larger tank, a smaller vehicle, a planned small-drop fee, or another supplier. Leave a semi off an order with only a couple of thousand litres of ullage. Leave any fuel tax credit out of the quoted cent.

Confirm the diesel grade loaded for that tank: a specified automotive diesel, handled as diesel the whole way. If the farm also runs highway trucks or a contracting arm on public roads, split commercial diesel from the paddock burn so the invoice and the use records stay separable.

Fuel tax credits on a working farm

Many farming uses of diesel are off public roads and may qualify for fuel tax credits. This is the paperwork shape, not tax advice. The Australian Taxation Office and your accountant outrank a fuel quote. Eligible businesses claim through the activity statement for fuel tax included in the price of fuel used in eligible activities. A lot of agricultural plant off public roads sits at the full rate: headers, tractors, sprayers, augers, pumps and generators doing farm work. Diesel burnt in a heavy vehicle over 4.5 tonnes gross vehicle mass on a public road generally draws the smaller credit, fuel tax less the road user charge. Grain trucks carting to receival are the usual case. Light vehicles at or under 4.5 tonnes on public roads generally sit outside the credit, including the ute run to town.

One tank can feed all three, so apportion. Rates are indexed, commonly in February and August, and the rules move. You buy a specified grade with fuel tax in the price, then claim what the use allows. There is no farm-diesel chemistry that arrives tax-free. Treating the highway trip as off-road eligible is how a file becomes an argument.

What the docket proves

The docket proves acquisition: date, litres, grade, place and tank, and whether the litres are observed or corrected to 15 degrees. It does not prove the header burned them. Where one bowser feeds paddock plant and on-road trucks, split issue records by machine or by crew, or keep separate tanks. Hour meters help when one tank has to serve both. A yearly guess is a weak claim file.

If contractors draw fuel you bought, agree in writing who may claim before the season. Two claims on the same litres will not both stand. The supplier does not lodge the activity statement. Ask for the tank name on the ticket, and keep the signed copy with the dip notes.

What farm diesel suppliers have to get right

A useful supplier names the vehicle, the lead time and the minimum for your district, asks for a wet-weather note, and refuses a track you have called soft. They put the seasonal spike on the board early, because their fuel transport shares drivers and gantry slots with every other property on the same rain. The access note has to reach the cab. A truck found the morning the district moves is how your load waits.

Atlas Fuel is a fair benchmark where the property sits on a run it loads. The company is Australian-owned and has operated from Kwinana Beach since 2010, with its own tankers, so dispatch and the driver are the same business. Planned supply covers Western Australia and extends to Queensland and Victoria. Name the district and take a yes or a no. A supplier whose other roster is mining fuel still treats the lane as a farm lane. Pit experience does not harden the ground.

The farm method is a metered drop into storage you control. Paddock machines then draw from your bowser or nurse tank. That is onsite supply aimed at the shed tank, on the vehicle the gate and the ground allow. ISO 9001 is the quality system to ask about, so the last load of harvest is handled like the first. Dipping the tank and draining the water stay with the farm.

Send district, working capacity, safe fill, coupling, hose reach, dry and wet access, and the truck class those notes imply. Add seeding, spray and harvest litres, the reorder line, who else draws, and whether highway trucks share the tank. Talk to dispatch with that brief and the quote can name a vehicle, a minimum and a window. A cent with none of that is a litre price, not a delivery.

• Seasonal litres for seeding, spray and harvest, plus contractor machines.
• Working capacity, safe fill, coupling, and ullage checked against the minimum.
• Dry and wet access, overhead clearance, and the vehicle that can leave.
• Reorder point from peak burn, real lead time, and the slip you have seen.
• A bowser record for anyone who is not the farm, agreed before they arrive.
• Dockets kept so off-road plant and on-road trucks can be split.
• An after-hours name, and a night track tested before the hot week.

FAQs

Frequently Asked Questions

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

When should a farm book diesel for seeding or harvest?

Before the district is in the same week as you. Give a window, the tank and the litres for that program, then keep a reorder point for the days that run long. Seeding needs the opening load in before the break becomes a queue at the gantry. Name the spray weeks, because a flat fortnightly drop misses them. Put contractor machines in the harvest nomination if they will draw your diesel. An empty gauge puts you in line with every neighbour.

What tank setup works for farm diesel delivery?

A labelled diesel tank with known working capacity, a safe fill that leaves ullage, a coupling the tanker can meet, and access a stated vehicle can use in the dry. The bund has to hold a spill, the vent has to breathe at the fill rate, and the fill point cannot be confused with petrol or anything else in the shed. Dip a tank that sat all summer and deal with free water before a fast drop stirs it. If the truck cannot turn, or the hose will not reach from solid ground, change the vehicle or the fill point.

What if the track is wet or the truck cannot turn?

Tell the supplier before the truck leaves the yard, on a wet-weather note that is allowed to say do not come. Black soil, soft sand, a headland or a creek flat can put a tanker on its belly. That recovery is often billable, and it is a spill risk. Where a semi cannot swing, a rigid may fit. If no loaded tanker will get back out, fill the home tank on a sound track and refuel the paddock from your own nurse tank. Put overhead lines and a long reverse on the same note, with a named spotter.

Can contractors draw from the farm tank?

Yes, if you decide before they arrive and you record the litres. A bowser code or a dip book signed at the shift is enough when someone uses it. Put their headers, chasers and support plant into the seasonal litres, or keep those machines on their own diesel. The supplier delivers to your tank and does not police the nozzle. Refuse unknown fuel tipped into your storage, and agree in writing who may claim any fuel tax credit on litres a contractor burns.

How do we avoid running out of diesel mid-harvest?

Order from peak daily burn, the lead time you have seen, and the slip you know, such as a Thursday call that becomes Saturday. About 7,500 litres a day with a two-day lead and a one-day slip means ordering while roughly 22,500 litres remain, with room left for the minimum drop. Use a different line for seeding. In regional Western Australia, Atlas Fuel has a 24/7 emergency path for Perth, Kwinana Beach and properties that can open the gate. Night still needs a person, light and a driveable track. Queensland and Victoria supply is planned.

Is farm diesel a different product from regular diesel?

Buy a specified diesel grade. Farm diesel is a use, not a separate chemistry in the hose. Confirm the grade on the docket. Fuel tax sits in the price, and eligible off-road use may be claimed later with the Australian Taxation Office. The word farm on the tank does not strip that tax at the nozzle. If a load looks or smells wrong, stop, dip for water, and test a bottom sample and a line sample before the header is filled.

How do we handle water, diesel bug and blocked filters?

Dip with water-finding paste, and take a bottom sample if the tank has been idle, the fuel smells sour, or filters start blocking. Diesel bug grows at the fuel-water interface. One bad machine points at that machine. Filters blocking across the fleet after a fill point at the tank. Keep hatches closed, drain rain out of the bund, and leave a water-block filter that has shut until you know why. If several assets misbehave, quarantine the tank and test a bottom sample and a bowser-line sample before the next fill.

What should a farm diesel quote and fuel tax credit file show?

Trace the quote to a named terminal gate price, a differential and freight, or to a fixed campaign figure that states who wears a terminal move and whether freight is inside. Minimum drop, waiting and after-hours sit on their own lines. Compare ex GST, and leave any fuel tax credit out of the cent. The docket shows product, litres, date, tank, and whether volume is observed or corrected to 15 degrees. Off-road plant, heavy trucks on public roads and light vehicles are different uses, so keep issue records where one tank feeds more than one. Eligibility sits with the ATO and your accountant.
