Recent survey research from Grain Producers Australia, Tractor and Machinery Association of Australia and the Society of Precision Agriculture Australia highlights a clear shift in how Australian grain growers are engaging with automation.

The survey of 220 Australian grain growers found that 45% reported using some form of semi-autonomous machinery, including GPS guidance and autosteer, rather than fully autonomous systems.

Tractors and sprayers are emerging as common entry points, with growers identifying productivity gains, time savings and reduced costs as key benefits. At the same time, cost, return on investment and connectivity remain important barriers to wider adoption.

That distinction matters.

Automation can improve how efficiently a task is done, but it does not automatically improve the decision behind that task. A machine can still apply the same fertiliser rate across an entire paddock.

This is where precision agriculture, and particularly variable rate decision-making, becomes important.

When automation is applied with VRT, growers can connect efficient machinery with data-driven agronomic decisions, creating greater opportunities for productivity, input efficiency and nutrient use efficiency.

For SPAA, the priority is practical extension: helping growers understand what these technologies are, where they sit on the adoption pathway, and what capability is needed to use them well.
