Based on late 2025 and early 2026 market reports, nitrogen fertilizer prices in Western Australia, e.g. ex-Kwinana, have remained elevated due to strong international demand and tight local supply. Here are the estimated bulk, ex-works/terminal prices for nitrogen fertilizers in the Kwinana area as of late 2025–early 2026:
Estimated Bulk Nitrogen Fertilizer Prices (Kwinana Area)
Granular Urea (46% N):
~$835–$1,004/tonne (ex-Kwinana): Prices saw increases in late 2025.
Note: As of September 2025, CSBP adjusted prices to roughly A$951/t ex-Kwinana.
Flexi-N (Liquid Nitrogen - UAN):
Production increased at the Kwinana Distribution Centre in 2025, with local supply available, but specific per-tonne prices vary based on volume and contract.
(CSBP, Summit)
Ammonium Sulfate (Granular):
Available through regional agricultural suppliers, with prices often reflecting high raw material costs (ammonia/sulfur).
(CSBP and various NK mixes)
Key Market Factors & Information
Supplier Activity:
CSBP(WesCEF/Wesfarmers) and CBH are major players in the Kwinana area for importing and distributing dry and liquid fertilizers.
Supply Outlook:
While international urea prices eased in mid-2025, local Western Australian prices remained high due to tight supply and early, strong import programs.
Price Volatility:
Prices are highly volatile and dependent on Indian import tenders and Chinese export quotas.
Disclaimer:
Fertilizer prices growers contact major suppliers in the Kwinana industrial area (e.g., CSBP, CBH, Summit Fertilizers, Nutrien Ag Solutions) for daily, precise quotes
(Summit wholly owned by Japanese trading house Sumitomo.)

Urea is the primary form of nitrogen (N) fertilizer used by wheat farmers in Western Australia. It is widely preferred due to its high nitrogen concentration (46%), which offers significant transportation and cost advantages compared to other nitrogenous fertilizers.
Here are the key details regarding nitrogen fertilizer usage for wheat in WA:
Widespread Use:
Urea is used extensively across WA's Wheatbelt, with 4.4 million hectares of agricultural land in Western Australia reported to have used urea in recent large-scale surveys.
Application Methods:
It is commonly applied by broadcasting (top-dressing) during the growing season, particularly to match nitrogen availability with crop growth stages.
Alternative/Complementary Methods:
While granular urea is dominant, the use of liquid Nitrogen (UAN, often branded as Flexi-N or similar) is also common, particularly as a flexible in-season or in-furrow option.
Timing:
Due to the risk of urea volatilization (loss to the atmosphere) on dry or alkaline soils, WA farmers often time applications for when the soil is moist or use nitrogen-fixing legumes in rotation to manage nitrogen needs.
While other products like ammonium phosphate (MAP/DAP) are used for foundational phosphorus, urea is the preferred, high-concentration nitrogen source for top-dressing and ensuring high yields.

OTHER items:
Urea is primarily produced in Australia at Incitec Pivot’s Gibson Island plant in Brisbane, which is currently the nation's only manufacturer.
However, the major $6 billion Perdaman Urea Project (to use gas from Woodside) is under construction on the Burrup Peninsula near Karratha, WA, set to produce 2.3 million tonnes annually.
NeuRizer, at SA gas fields, also possible.
Ammonia

Ammonia manufacturing in Australia is a significant industry primarily producing around 410,000 tonnes of hydrogen-based ammonia annually, predominantly for fertilizers and mining explosives using natural gas via the Haber-Bosch process. Major production centers are located in Western Australia and Queensland. The industry is rapidly transitioning toward green ammonia, with key projects like Yara Pilbara, Orica Kooragang Island, and Allied Green Ammonia developing renewable hydrogen-based production.
Key Aspects of Australian Ammonia Production
Production Process:
Currently, natural gas and water are converted into hydrogen and carbon dioxide (steam methane reforming), which is then combined with nitrogen in a Haber-Bosch reactor.
Major Producers & Locations:
There are seven main production sites, mostly in Queensland and Western Australia.
Key players include Yara Pilbara (producing 840,000 MT annually) and CSBP in Kwinana.
Transition to Green Ammonia:
To reduce emissions, projects are exploring electrolytic hydrogen from water using renewable energy, aiming to decarbonize the process.
Future Outlook: The Future Made in Australia strategy provides over AUD$15 billion to support the green hydrogen sector, positioning Australia as a potential leader in low-emission ammonia.
Despite the potential, renewable hydrogen-based ammonia currently costs about twice as much as natural gas-based production. However, with government incentives and falling renewable costs, green ammonia is becoming more economically viable.

Australian manufacturer CSBP has shut down its 90,000-100,000 t/yr superphosphate (SSP) manufacturing plant in Kwinana, and will switch to an import model going forward. The company said the plant is going into "care and maintenance", and the facility will be repurposed to increase CSBP's storage capacity.
(Incitec Pivot Limited manufactures superphosphate at Geelong and Portland in Victoria from imported phosphate rock. )
