How irrigation transformed the Riverina into one of Australia’s most productive agricultural regions

People visiting the Riverina for the first time are often surprised by the scale and diversity of agriculture they encounter. Within a relatively short drive they may pass rice fields, citrus orchards, vineyards, cotton, almonds, vegetables, grain crops and livestock enterprises. One of the questions we are asked most frequently is, “How is it possible to grow so many different crops in one region?”

The answer begins with water and the development of Riverina irrigation.

More specifically, it begins with one of Australia’s most significant irrigation systems and a remarkable vision that transformed vast areas of inland New South Wales into highly productive farming country.

Before irrigation

Before irrigation was introduced, much of the Riverina supported extensive grazing enterprises. The landscape was well suited to sheep and cattle, but rainfall alone limited the range of crops that could be grown reliably.

Farmers, then as now, worked with the conditions they were given. Good seasons produced excellent results. Dry years required careful management and patience.

Like much of inland Australia, farming was always closely tied to the variability of the climate.

A bold vision

During the early twentieth century, governments began investing in irrigation infrastructure throughout the Murrumbidgee Valley. Large dams, supply channels, regulators, weirs and distribution systems were constructed to make better use of available water.

The development of the Murrumbidgee Irrigation Area fundamentally changed what could be achieved across the region.

Water could now be delivered where it was needed and, just as importantly, when it was needed. This provided farmers with opportunities that had previously been impossible. New towns expanded. Processing industries developed. Transport networks improved.

Entire communities grew alongside the irrigation system.

More than simply supplying water

Visitors sometimes imagine irrigation is little more than turning on a tap.

Modern irrigation is considerably more sophisticated. Every megalitre is carefully managed. Farmers consider soil type, crop requirements, weather forecasts, evaporation rates and the stage of plant growth before deciding when and how much water to apply.

In recent decades, technology has improved this process even further. Many farms now use satellite guidance, soil moisture monitoring, automated channel systems and sophisticated data collection to help improve irrigation efficiency.

These technologies not only assist crop production but also help farmers make the best possible use of a valuable and limited resource.

A region of remarkable diversity

Reliable irrigation has allowed the Riverina to become one of Australia’s most diverse agricultural regions.

Depending on the season, visitors may see rice, cotton, citrus, almonds, walnuts, wine grapes, maize, soybeans, vegetables, cereals and livestock enterprises operating within the same district. Many farms have diversified over time, growing several different crops as market conditions change. This diversity provides resilience. It also creates fascinating opportunities for visitors interested in understanding Australian agriculture.

On a single day’s tour it is often possible to see several completely different industries, each with its own production systems, processing facilities and markets.

Irrigation supports entire communities

The benefits of irrigation extend well beyond individual farms.

Many of the industries that visitors encounter throughout the Riverina exist because agricultural production supports them, for example:

• Rice mills.
• Cotton gins.
• Citrus packing sheds.
• Fruit juice factories.
• Nut processors.
• Transport businesses.
• Agricultural engineering firms.
• Research organisations.

Each plays an important role within the regional economy. Together they provide employment, encourage investment and help sustain vibrant rural communities.

This broader picture is something many visitors find particularly interesting. Agriculture is not simply about what happens in the paddock. It supports a network of businesses that extends throughout the region.

Water management continues to evolve

One of the common misconceptions about irrigation is that the system remains unchanged from year to year.

In reality, irrigation is constantly evolving. Australian farmers have become exceptionally skilled at adapting to changing climatic conditions, advances in technology and evolving water management policies. Some seasons bring abundant water. Others require difficult decisions about which crops can be grown and how available water should be allocated. These challenges are part of modern farming.

Visitors often appreciate hearing directly from farmers about how these decisions are made and how businesses continue to adapt while maintaining productivity.

Seeing irrigation in action

Many of our tours include opportunities to see irrigation infrastructure operating in the field.

Depending on the itinerary, visitors may inspect irrigation supply channels, regulators, pumping systems and modern irrigation layouts while hearing directly from the people who use them every day.

One of the observations we hear most frequently concerns the remarkably flat paddocks found throughout many irrigation districts. These carefully levelled fields are not accidental. Satellite-guided earthmoving equipment reshapes paddocks so irrigation water can be distributed evenly and efficiently across the entire field. Visitors are often fascinated to learn about the precision involved in preparing land before a single seed is planted.

It is another reminder that successful farming depends upon careful planning long before harvest begins.

Looking beyond the landscape

It is easy to admire the Riverina simply for its scenery. Wide open paddocks, long rows of citrus trees, vineyards stretching towards the horizon, cotton fields, rice crops and grazing livestock …

Yet behind every landscape lies decades of planning, engineering, scientific research and practical farming knowledge.

Understanding that history allows visitors to appreciate not only what they are seeing, but why it exists. For many people, irrigation is one of the defining stories of the Riverina. Without it, the region would look very different.
