Contract Spraying Rates in Australia: Boom Spray, Drone and Aircraft Costs for 2026

Getting a spray job done in 2026 costs more than it did three years ago, and what you pay varies widely depending on how the work is done. Boom spray, drone and aerial all have a place on farm. Knowing the going rate for each helps you budget properly, compare quotes with confidence, and choose the right method for the job.

With the BOM forecasting a drier-than-average autumn across the eastern grain belt this year, pre-plant herbicide programs are under time pressure. Getting a spray contractor lined up early is not optional. Here is what the rates look like in 2026, and what actually drives the price.

Boom Spray Rates per Hectare

Boom spray is still the most common method for broadacre paddocks. The going rate across NSW and Queensland in 2026 sits between $8 and $18 per hectare, depending on several factors.

Paddock access, terrain and drive distance from the contractor's base all affect the price. So does the job itself. A single-product knockdown on a clean paddock is cheaper than a multi-product tank mix on a rough block with gates and creeks. Minimum call-out fees are standard, particularly in more remote areas, so small jobs under 100 hectares often cost more per hectare than larger runs.

Contractors with newer, wider rigs (36m+ booms) can work faster and sometimes price keener on large open paddocks. For anything over 500 hectares in the Liverpool Plains or Darling Downs, it is worth getting two or three quotes to see what the competitive rate looks like this season.

Typical Boom Spray Rates (2026)

Agricultural Drone Spraying Costs

Drone spraying has moved from novelty to practical option in the last two years. The DJI Agras T40 and T50 are the rigs most Australian operators are running, and coverage rates have improved enough that drones are now genuinely competitive for certain jobs.

Rates in 2026 run from $18 to $35 per hectare. That is higher than a boom rig, so the question is always whether the job justifies it. Drones make sense on rough or hilly country where a boom sprayer can't safely operate, on blocks with obstacles like power lines or trees, or on smaller isolated paddocks that are not worth the call-out cost for a full boom rig.

Most drone operators charge a minimum call-out fee in the $300 to $500 range. Application rates are lower than a boom (typically 10–20 L/ha vs 50–100 L/ha for boom), so if your program requires high water volumes it may not suit. Worth checking with the operator before booking.

Aerial Spraying Rates: Fixed-Wing and Helicopter

Aerial spraying costs between $20 and $45 per hectare, with the rate depending heavily on area, terrain, product type, and how far the aircraft has to travel to the job.

Fixed-wing is the most cost-effective option at scale. On large open blocks of 500 hectares or more in flat country, a fixed-wing operator can work fast enough to bring the per-hectare rate down significantly. It is well-suited to broad-scale broadleaf programs in cotton country, aerial fertiliser spreading, and jobs where you need coverage turned around quickly ahead of rain.

Helicopters are more versatile but more expensive. They work in tight country, around tree lines, and on smaller or irregular-shaped paddocks. Expect to pay at the higher end of the range for helicopter work.

Ferrying costs can add up fast if the operator is travelling more than an hour to your property. It is worth asking about mob-up logistics when getting a quote, particularly if you are in more remote country south-west of Dubbo or out past St George.

Side-by-Side: Which Method for Which Job?

The right method depends on your paddock, your program, and your budget. Here is a practical breakdown.

What Actually Drives the Price

A few things push rates up or down regardless of which method you are using.

Distance to your property is a big one. A contractor an hour away from your gate is costing themselves fuel and time before they start. That either gets priced in explicitly or folded into the rate.

Timing matters too. Spray contractors are busy in the lead-up to planting windows. Right now, with autumn sowing approaching and BOM forecasts pointing dry, demand for pre-plant knockdown programs is building. If you leave it until late April you will be competing with everyone else in the district.

Product supply and tank mixing adds time and cost. Multi-product programs with strict withholding periods or compatibility requirements take longer to set up. Some contractors charge a mixing fee on top of the area rate.

Repeat business is worth mentioning. Contractors price returning clients differently to one-off jobs. If you have used someone before and paid on time, you are a better prospect than a cold call in peak season.

Finding a Spray Contractor Before the Rush

The NFF estimated a shortage of 38,000 agricultural workers across Australia last year. Spray contractors are in the same pool. Getting organised now, before the autumn planting window tightens, is the practical move.

AgPages connects farmers directly with vetted spray contractors across NSW and Queensland. You can post a spraying job in a couple of minutes and have contractors reach out to you, rather than spending a morning ringing around. If you want to understand what contractors are earning on jobs like this, the contractor revenue guide covers the economics in detail.

Rates will not come down as the season gets busier. If you know you have a program to run in April or May, it is worth making the calls now.

The Bottom Line on Spray Rates

Boom spray is the cheapest option per hectare on accessible broadacre country. Drones fill a real gap on rough or awkward ground. Aerial makes sense at scale or when you need speed and coverage in a short window.

Rates across all three methods are up compared to two years ago, and availability in peak season is genuinely tight in some districts. Getting quotes in March and April, ahead of the autumn crunch, is worth the effort.
