A spray drone rarely replaces the boom outright. How funders treat a drone as security, why terms run shorter, and when buying beats hiring a contractor.
Quick Answer
Agricultural spray drone finance works like other equipment finance, but funders read a drone as an asset with a short technology life, so terms run shorter and the batteries, chargers and support kit usually go in the same deal. Whether to buy, hire a contractor or keep the boom depends on your hectares, how often paddocks are too wet for ground rigs, and who holds the licences to fly and spray. Lenders also check what the drone will be worth at the end of the term before setting it.
Also called: ag drone finance, spray drone finance, agricultural drone finance. All three describe the same thing: finance for a remotely piloted aircraft used to spray crops or pasture for a business.
Should you buy a spray drone, hire a contractor or keep the boom spray?
For most farms the choice is not drone or boom: it is buy, hire or keep the boom as the main rig, with the drone filling the jobs a ground rig cannot reach. The common belief is that a drone replaces the boom spray outright. In practice a drone covers far fewer hectares per hour than a wide boom, so on broadacre country it tends to work alongside it, taking the wet paddocks, the steep or treed corners, the fence lines and the spot work where a boom would cause wheel damage or simply cannot go.
That changes the finance question. If the drone is a second tool, the funder is lending against a smaller, faster depreciating asset while the boom keeps doing the heavy work. If you are planning a bigger move, such as adding country or changing the cropping program, the drone decision usually sits inside a wider plan like the ones covered in farm expansion finance.
Which of the three ways to get the spraying done suits your farm?
| Factor | Buy a spray drone | Hire a contractor | Keep the boom spray |
|---|---|---|---|
| What you fund | Drone, batteries, chargers, generator and mixing gear, usually as one equipment finance package | Nothing upfront; you pay the contractor per hectare out of cash flow | Nothing new if the boom is paid off; a replacement boom is a larger, longer deal |
| Timing control | High: you spray when the window opens | Low to medium: you wait in the contractor's queue at peak times | High, unless paddocks are too wet to drive |
| Wet or steep ground | Strong: no wheel tracks or bogging | Strong, if the contractor runs drones | Weak: the main reason farms look at drones |
| Licences and labour | You or a staff member need the CASA approvals and a state chemical licence | The contractor carries the licences and the drift risk | State chemical licence only; no aviation approvals |
| Technology risk | Highest: models change quickly and resale values fall | None: the contractor carries it | Low: booms hold value well against drones |
| How a funder reads it | Shorter term, deposit or wider security more likely | Not a finance question; a running cost in your accounts | Familiar farm asset with an established resale market |
Check these four things before you buy:
- Wet seasons. Wet paddocks regularly keep ground rigs out in your spray windows. If they rarely do, the boom stays the main rig.
- Contractor reach. Contractors cannot get to you inside the spray window. If they can, hiring usually costs less than a repayment.
- Licences. Someone on the farm will hold the CASA approvals and the state chemical licence and fly the drone. If nobody wants the aviation paperwork, hire.
- Work volume. There is enough on-farm or contract work to keep the drone busy. A handful of jobs a year rarely covers a repayment, especially when cash flow is already tight.
What does an agricultural spray drone setup cost to finance?
A working spray drone setup costs well more than the drone itself, because batteries, fast chargers, a generator, mixing and loading gear and often a support vehicle are all part of getting it into the paddock. Funders generally want to see the whole kit on one supplier quote, so the finance covers a setup that actually works rather than a drone with nothing to charge it.
As a rough indication only, a single large spray drone with a working set of batteries and a generator typically lands somewhere around $40,000 to $90,000 before any support vehicle, and a two drone setup can run well past that. Payload size, battery count and the supplier's training package move the figure a long way, so treat these as example numbers, not quotes. Prices vary by supplier and change as new models arrive.
Can the support vehicle go in the same deal?
A support ute or trailer can usually go in the same deal or a linked one, and many funders prefer it because a vehicle is an asset they understand well. Bundling the two can help a lender get comfortable with the drone portion. If you are new to how this kind of lending works, what asset finance is covers the basics of how the asset secures the loan.
Spare batteries bought later are usually treated as a running cost rather than a new finance deal. Budget for them, because battery life is one of the first things to wear on a spray drone.
Will a lender take a spray drone as security?
Many equipment funders will take an agricultural spray drone as security, but fewer of them take drones than take tractors or boom sprays, and the ones that do read a drone more like technology than like farm machinery. Major banks often prefer to fund it inside a broader facility, while some non-bank lenders and specialist funders will write a standalone chattel mortgage over the drone.
The first test is whether the drone can be identified and resold. That means a serial number they can register on the PPSR, a model supplied through an Australian dealer with warranty and service support, and evidence that it is used in a business rather than as a hobby. A grey import with no local support is a much harder sell.
Where a funder will not rely on the drone alone, the deal is usually structured one of three ways: bundled with the support vehicle, secured more broadly over other business assets as additional security, or written on a shorter term with a larger deposit. If your financials are behind, which is common at the end of a busy season, low doc asset finance may still be an option with bank statements and BAS.
How do lenders treat fast changing drone technology and resale value?
Lenders treat a spray drone as an asset with a short technology life, which means shorter terms and smaller balloons than you would see on a tractor. New models with bigger tanks, better spray systems and longer flight times arrive quickly, and each new release pushes down the value of older ones. A funder sets the term so the loan is paid down before the drone's market value falls below what is owed.
The result is terms matched to useful life, which varies by lender. On the drone deals we have placed, terms typically run around 2 to 4 years, compared with the 5 to 7 years that is common for a tractor. A residual value at the end, if a funder offers one at all, tends to be small. The trade off between a lower repayment and a larger final payment is set out in balloon payments and residual values.
Fast depreciation cuts both ways. It is why funders are cautious, but it also means the tax deduction comes through faster. How that plays out in your return is a question for your accountant.
Which CASA licences and certificates do you need to spray with a drone?
The CASA approvals you need depend mainly on the size of the drone and whether you fly it commercially, and large spray drones typically need a remote pilot licence and a remotely piloted aircraft operator's certificate (ReOC). CASA's Get your ReOC guidance treats aircraft up to 25 kg differently from those over 25 kg, and a loaded spray drone can sit in the heavier class.
The rules for flying over your own land can differ from the rules for flying for paying clients, and CASA updates its requirements from time to time. Confirm the current position with CASA before you sign a contract on a drone, because a licence you cannot get in time is a drone that sits in the shed while repayments run.
Funders financing a contract spraying business commonly ask to see the remote pilot licence and the ReOC, or proof the application is under way. For a farmer spraying their own paddocks, the question is more likely to come up as part of insurance than finance.
Which state chemical and drift rules apply to drone spraying?
Chemical use is regulated by each state and territory, so the licence you need and the drift rules set by each state apply on top of the CASA approvals. Some states treat drone application as a form of aerial spraying with its own licence or endorsement; others fold it into their general chemical user rules. The label on the product you spray still governs rates, buffers and weather conditions.
Drift is the part that carries real financial risk. A drift complaint from a neighbour can lead to regulatory action and an insurance claim, so most funders expect the drone to be covered by insurance that names it, with the financier noted. Check that your policy covers drone operation and spray drift specifically, not just the farm's general liability. Comprehensive insurance on the asset itself is a standard condition of most equipment finance.
How do lenders read per hectare contract spraying income?
Lenders read per hectare contract income the same way they read any seasonal service income: they want to see it in the bank account across a full season, with repeat farm clients rather than one large job. A contractor who sprays for the same dozen farms every year is a much stronger file than one with a single big client who could switch providers next season.
The documents usually come down to bank statements showing the spraying deposits, BAS for the same period, and a list of regular clients. Many drone operators start as a sole trader alongside their own farming, which is fine, but the lender will want to separate the farm income from the contract income to see what the drone actually earns.
A newer contract spraying business with less than a full season behind it is harder, though not impossible. The usual answer is a larger deposit or a lender that specialises in newer ABNs, as covered in equipment finance for a new ABN. If the drone business is part of buying or setting up a new property, read the lending side alongside buying a farm. Some lenders will also accept a low doc approach where the BAS is current but tax returns are not yet lodged. More on lending for operators like this is on the Business Owners Hub.
Can drone repayments follow the spraying season?
Some funders will set drone repayments to follow the spraying season, with larger payments in the months the work comes in and smaller ones in the quiet months, though fewer offer it on a drone than on a header or tractor because of the shorter term. Seasonal and harvest timed repayment structures for farm machinery are covered in detail in our farm equipment finance guide, and the same principles apply here. If the drone is bought near the end of the financial year, ask your accountant whether the instant asset write-off or other depreciation rules change the timing that suits you best.
A spray drone is usually a second tool, not a replacement for the boom, and funders treat it as a short technology life asset. Expect the whole kit, from batteries to the support ute, to go into one package, terms shorter than on farm machinery, and a lender that wants the drone identifiable, insured and backed by local support. CASA approvals and your state's chemical licence need to be in place before the drone can earn, and contract spraying income is read over a full season with repeat clients.
Key takeaway: price the full setup, check the licences first, then compare the repayment against what you pay a contractor for the same hectares.Frequently Asked Questions
An agricultural spray drone costs more to finance than its sticker price, because the batteries, chargers, generator and mixing gear are usually funded in the same package. As an indication only, a single large drone with a working battery set and generator typically lands around $40,000 to $90,000 before any support vehicle, varying by supplier. A broker can structure equipment finance around the full kit on one quote.
Many lenders accept an agricultural spray drone as security, but fewer funders take drones than take tractors or boom sprays, and those that do usually set a shorter term. They want a serial numbered model with local dealer support and a realistic residual value. Where a funder will not rely on the drone alone, it is often bundled with the support vehicle or secured over other business assets.
Contract drone spraying income can be enough to get finance when it shows up in your bank statements across a full season and comes from repeat farm clients. Lenders are more cautious with a single large client or less than one season of trading. A newer business may need a larger deposit or a lender that works with new ABNs.
Spraying with a drone on your own farm still needs the right CASA approvals and a state chemical licence, though the CASA requirements depend on the drone's size and how you operate it. CASA treats aircraft up to 25 kg differently from heavier ones, so confirm the current rules with CASA before you buy. The same applies whether you fly as a sole trader or through a company.
Whether you can write off a spray drone in the year you buy it depends on the instant asset write-off rules for that income year and your business's turnover. From 1 July 2026 the threshold is $20,000 per asset for eligible small businesses, so a full spray drone setup usually costs more than that and is depreciated instead. Financing the drone does not by itself stop you claiming, because a chattel mortgage puts ownership with your business from day one. Confirm your eligibility with your accountant.
