The Department of Agriculture and Food, Western Australia (DAFWA) has a strong research, development and extension (RD&E) focus on wheat production with investments right along the wheat value chain from pre-breeding and agronomic research to support variety development through to pest and disease management, grain quality assessment and export market intelligence through the Australian Export Grain Innovation Centre (AEGIC).
The area sown to wheat in Western Australia (WA) over the past 20 years has remained relatively stable at between four to five million hectares but over this same period production has increased strongly with improved yields. As a result we are seeing production of 8-10 million tonnes per annum.
Grown under rain-fed conditions WA wheat production can fluctuate from season to season as can be seen in the chart above.
Seasonal variability, particulary since the year 2000, combined with a high Australian dollar (export wheat is usually sold in US dollars) has placed increasing pressure on wheat profitability. Despite this, a recent study of WA wheat producers found almost two thirds of WA farms can be classed as 'growing' or 'strong' due to their use of technology to create economies of scale and their managerial and social characteristics.
Indonesia is by far Western Australia's largest wheat export market accounting for an average 2.3 million tonnes each year. DAFWA (through AEGIC) is actively engaged with Indonesian milling companies to gain a better understanding of their grain quality requirements and the performance of WA wheat varieties in the milling and baking process.
WA is the world’s major supplier of wheat for Japanese white salted udon noodles – a one million tonne market supported by a long collaboration between the DAFWA and Japanese flour millers. The department has hosted visiting Japanese noodle manufacturers and flour millers since 1990 - a program that has enabled WA to be in tune with Japanese quality expectations of WA noodle wheat varieties.
WA produces white grained wheat varieties that generate a bright white flour and high flour milling yield. WA wheat typically has low moisture content, low discolouration and high bulk density and is suitable for a range of products including different breads. WA's dry harvesting environment results in low moisture content and low risk of weather damaged grain.
Major wheat milling grades in WA are:
Australian Hard (AH): used for breads; about 12% protein.
Australian Premium White (APW): used in blends for breads including European and flat breads, some noodles and steamed breads; about 10.5% protein.
Australian Standard White (ASW): used for flat breads, steamed (Asian) breads, noodles; 9-10.5% protein.
Australian Standard Noodle Wheat (ANW): specifically for Japanese udon noodles; 9.5-11.5% protein.
Australian Premium White Noodle (APWN): WA only. Used for blending; 10.5-11.5% protein.
Australian Soft: used for biscuits, cakes, steamed buns; less than 9.5 % protein.
