Drone Spraying Cost in Australia: Per Acre and Per Hectare Guide
Drone spraying cost in Australia is usually higher per hectare than a clean boom spray job, but that is not the whole story. Drones earn their keep where access is the problem: wet corners, steep country, small blocks, trees, powerlines, odd shapes and jobs too fiddly for a ground rig.
Use this guide as a planning aid before you post a spraying job. The final number still needs a real contractor quote, because product, water rate, travel and timing can move the price quickly.
Quick answer
As a planning range, drone spraying commonly sits around $18 to $35 per hectare, or roughly $7 to $14 per acre. Small jobs, travel, refill setup, obstacles, urgent timing and chemical handling can push the quote higher.
If the paddock is clean, large and accessible, compare the drone quote with boom spraying before booking.
Drone Spraying Cost per Hectare and Acre
Most farmers think in hectares, acres or paddock totals, while contractors may quote per hectare, hourly or as a minimum call-out. Keep the quote style clear before comparing options.

What Changes a Drone Spraying Quote
- Area and shape. One compact block is easier to price than several broken corners.
- Travel. A contractor already near Narrabri, Moree, Gunnedah, Dalby or Goondiwindi may quote differently to one moving gear across districts.
- Water rate and product. Label requirements, tank mix and refill setup affect work rate.
- Obstacles. Trees, powerlines, sheds, houses and sensitive neighbours all need to be mapped upfront.
- Timing pressure. A same-day job after rain will not price like a flexible job with a clear window.
When Drone Spraying Beats a Boom Spray Rig
Drones are usually not the cheapest option for clean broadacre spraying. A boom rig can cover big, open country faster and cheaper when access is good.
Drone spraying starts to make sense when ground access costs you more than the higher per-hectare rate. Think wet black soil, odd-shaped paddocks, steep country, spot spraying, crop damage risk or blocks that are too small to attract a ground rig without a minimum charge.
What to Include Before You Ask for a Quote
A vague “how much per acre?” message usually creates a vague answer. Contractors need enough detail to know whether the job fits the drone, the label and the weather window.
Drone Spray Job Brief
- Hectares or acres to spray
- Nearest town and access notes
- Crop, pasture or fallow status
- Target weed, pest or disease
- Product plan and water rate
- Refill water source and distance
- Trees, powerlines and obstacles
- Ideal spray window
Compare Drone, Boom and Aerial Before Booking
If you are still choosing the method, read the drone vs boom vs aerial spraying guide. If you want broader rate ranges across all spray methods, use the contract spraying rates guide.
Once you know the job, post it on AgPages with the details above. Contractors can then respond with a quote that reflects the real paddock, not a guess from a text message.

Frequently Asked Questions
Is drone spraying cheaper than boom spraying?
Usually no. Drone spraying is commonly dearer per hectare, but it can be better value where a boom rig cannot access the paddock safely or efficiently.
Can drone spraying be quoted per acre?
Yes, but ask the contractor to show the hectare equivalent as well. It keeps comparisons cleaner when other spraying quotes come back per hectare.
Do drone spray quotes include chemical?
Not always. Confirm whether the quote includes chemical, water, travel, refill time, mapping and GST before comparing prices.
