Wheat is Australia's most valuable crop, generating around $4 billion in export revenue annually. It is grown in Western Australia, New South Wales, South Australia, Victoria, and Queensland. However, climate change is putting pressure on wheat yields in the southwest of Western Australia, with lower rainfall, later starts to the growing season, and higher temperatures during the growing season. The increase in wheat yields since 1980 has been attributed to technological and management improvements, but the rate of yield increase has plateaued, and yield variability has increased. While wheat yields have remained largely the same over the 26 years from 1990 to 2015, potential yields have declined by 27% during this period.

Wheat is a winter crop in Australia
Wheat is a major crop in Australia, with the country being the world's second-largest wheat exporter. Wheat is a winter crop in Australia, with sowing beginning in autumn and harvesting taking place in spring and summer. The main wheat-producing states in Australia are Western Australia, New South Wales, South Australia, Victoria, and Queensland.
The climate in these wheat-growing regions varies, but generally, wheat in Australia is grown in areas with low precipitation, low winter temperatures, and high rainfall (>500 mm per year). In particular, the Mediterranean semi-arid regions of southern Australia receive between 150 and 400 mm of rainfall per year and are an important wheat-growing region for both local consumption and export. These regions have seen the effects of climate change, with reduced growing season rainfall and establishment opportunities during autumn. Despite this, the 2024-25 season is expected to see a record-breaking winter crop production in Australia, with wheat production estimated to increase to 34.1 million tonnes, up 31% from the previous year.
Winter wheat in Australia is typically sown on the first autumn rain and requires high nutrition to achieve high winter dry matter production and good grain recovery. Higher sowing rates generally increase dry matter production and have no negative effect on grain yield or quality. The success of winter wheat in Australia is also due to its fit into the farming system, allowing producers to increase production potential and take advantage of better seasons. For example, dual-purpose crops can provide valuable winter forage for livestock production and increase subsequent pasture availability by reducing grazing pressure on pastures.
The area sown to wheat in Western Australia has remained relatively stable over the past 20 years, but production has increased due to improved yields. Western Australia generates about 40% of Australia's total wheat production, with most of it exported to Asia and the Middle East. The wheat produced in Western Australia is typically white-grained wheat with low moisture content and high bulk density, making it suitable for a range of products, including different types of bread.
Wheat has a long history in Australia, with James Ruse, a First Fleet convict, considered the father of the Australian wheat industry. By the mid-19th century, wheat became Australia's most important crop, with new colonies in Victoria, South Australia, and Western Australia contributing significantly to wheat production. Australian wheat exports began in 1845 but only became regular in the 1870s with the invention of new land-clearing methods. After the Second World War, wheat became Australia's single most valuable agricultural product, and it continues to be a major source of agricultural employment and export revenue.

The state's dry harvesting environment contributes to the low moisture content and low risk of weather-damaged grain.
NSW, SA, Victoria, and Queensland also play significant roles in wheat production in Australia. The mid-19th century saw a significant increase in land cultivation in these states, with Victoria, SA, and WA becoming particularly important in wheat production. The success of wheat harvests in the 1870s led to the establishment of flour mills across the country, with around 500 mills operating by the 1930s.
Australia is a world leader in producing quality, safe, and clean food-grade wheat, with its wheat valued for its high performance in a full range of uses. The country produces various wheat types, including Australian Prime Hard (APH), Australian Hard (AH), Australian Premium White (APW), Australian Noodle Wheat (ANW), Australian Standard White (ASW), Australian Premium Durum (ADR), and Australian Soft (ASFT).

The majority of Australian wheat is sold overseas, with WA producing 40% of the nation's total wheat production. More than 95% of WA wheat is exported, predominantly to Asia and the Middle East. The main export markets include Indonesia, Japan, South Korea, Malaysia, Vietnam, and Sudan.
WA wheat is in high demand in these regions due to its unique characteristics. WA's dry harvesting environment results in wheat with low moisture content, low risk of weather damage, low discolouration, and high bulk density. These qualities make it ideal for various products, including different types of bread and noodles. WA is the world's leading supplier of wheat for Japanese white salted udon noodles, a collaboration that has been ongoing since the 1990s.
The success of WA wheat exports is also attributed to the state's favourable climate and agricultural practices. Wheat is a major winter crop in Australia, with sowing starting in autumn and harvesting occurring in spring and summer. WA's wheat production occurs on mostly family-run farms ranging from 1000 to 20,000 hectares in size. The area sown to wheat in WA has remained stable over the past 20 years, but production has increased significantly due to improved yields.
To maintain its competitive edge, WA invests in research and development in wheat production. The Department of Primary Industries and Regional Development (DPIRD) works closely with organisations like the Australian Export Grain Innovation Centre (AEGIC) to enhance variety development, pest and disease management, and grain quality. DPIRD's collaboration with Indonesian milling companies is an example of their proactive approach to understanding market demands and ensuring the success of WA wheat in export markets.
In summary, WA wheat is predominantly exported to Asia and the Middle East, contributing significantly to the state's economy and Australia's agricultural employment. The quality and characteristics of WA wheat, coupled with dedicated research and development, have established it as a preferred choice in these export markets.

Wheat yields have been affected by climate change
Wheat is the major winter crop grown in Australia, with the sowing season starting in autumn and harvesting occurring in spring and summer. The main wheat-producing states are Western Australia, New South Wales, South Australia, Victoria, and Queensland. Western Australia generates about 40% of Australia's total wheat production, with more than 95% of this exported, predominantly to Asia and the Middle East.
Wheat yields in Australia have been affected by climate change in several ways. Firstly, climate change has led to lower rainfall in certain regions, particularly during the autumn and spring seasons. This has impacted the start of the growing season, with later commencement dates. Additionally, higher temperatures during the growing season have affected crop health and productivity. The combination of declining rainfall and increasing temperatures has reduced the potential yield in some areas.
The impact of climate change on wheat yields is complex and varies across different regions. In Western Australia, for example, the adoption of new technologies and management systems has helped to mitigate the negative effects of climate change. Between 1990 and 2015, actual yields remained relatively steady due to these advancements. However, without these technological improvements, water-limited yield would have dropped by an estimated 27%.
On a global scale, wheat yields have also been influenced by changing climatic conditions. According to a study published in 2025, global wheat yields are around 10% lower than they would have been without the impact of climate change. This study examined data from the past 50 years and found that heat and drought conditions negatively impacted wheat supplies in key grain-producing regions, including parts of Europe, China, and Russia.
While rising CO2 levels can enhance plant growth through a process called "CO2 fertilization", the benefits of this may be outweighed by growing water stress. A 2019 study suggested that yield losses for wheat likely exceeded any advantages from increased CO2 levels over the past 50 years. Additionally, higher temperatures can affect the length of growing seasons and accelerate crop maturity, further influencing wheat yields.

Farmers have stabilised yields with improved practices
Wheat is Australia's major winter crop, with sowing starting in autumn and harvesting occurring in spring and summer. Western Australia, New South Wales, South Australia, Victoria and Queensland are the major wheat-producing states. Wheat is Australia's most valuable agricultural product, generating around $4 billion in export revenue annually.
Western Australia (WA) is the largest exporting state, generating A$2-5 billion for the state economy each year. WA produces white-grained wheat varieties that generate high flour milling yield and a bright white flour that is suitable for a range of products.
However, climate change is putting pressure on wheat yields in the southwest of Western Australia. Lower rainfall, a later start to the growing season, and higher temperatures during the growing season are all factors impacting wheat yields. The reduction in the rate of increase of wheat yield and water use efficiency since 2000 has been attributed to growers reducing their inputs in response to climate conditions.
To stabilise yields, farmers have adopted new technologies and management systems. For example, the adoption of new practices such as minimum tillage, soil amelioration, stubble retention, early sowing, and integrated weed control has increased wheat yields since 1980. Modelling indicates that increased atmospheric carbon dioxide concentration over the last 50 years has also increased yield potential.
Additionally, the Department of Primary Industries and Regional Development (DPIRD) in WA has a strong research, development, and extension (RD&E) focus on wheat production. DPIRD supports wheat production through investments in pre-breeding and agronomic research, pest and disease management, grain quality assessment, and export market intelligence through the Australian Export Grain Innovation Centre (AEGIC).
To further improve wheat yields, studies have suggested adapting sowing dates and crop phenology. By shifting to earlier optimum sowing windows and earlier maturity types, wheat productivity can be raised in Australia. This strategy can help minimise the impact of projected stresses such as heat and drought, which are expected to become the major limiting factors by 2050.
