Cauliflower Season

Cauliflower is in season in Australia through the cooler months, with peak supply from June to August when Victoria, Queensland and New South Wales are all producing at full pace. You can usually find good cauliflower from May through to October, with the thinnest months being December to March when summer heat makes quality heads harder to grow. It's a solidly Australian crop. Imports are negligible and nearly everything on the shelf was grown here.

Cauliflower is in season across winter and spring in Australia, with peak supply from June to October.

The edible white head of cauliflower (Brassica oleracea var. botrytis) is technically an immature flower (growers call it the curd) and its quality is tightly tied to temperature during maturation, as the DAF Qld CTT report outlines. Too much heat causes riceyness and misshapen heads. Late frosts can also affect quality close to harvest. Most commercial crops are transplanted, with early varieties ready in about 10–12 weeks. Varieties are classified as spring, summer, autumn or winter types, and growers cycle plantings to maintain consistent supply. Production can occur year-round in cool, mild areas such as south-west WA and temperate Victoria, though the bulk of national supply moves through the June to September window.

Cauliflower was first cultivated in Europe. Italy, France, England, Germany and the Netherlands are the traditional development centres, with more heat-tolerant Indian types also contributing genetics that extended the crop's range into warmer districts, as the DAF Qld CTT report notes. The Australian industry shifted to hybrid varieties in the late 1980s after trials across the Adelaide Plains and Adelaide Hills evaluated more than 60 cultivars, per AUSVEG VG812. Hybrids brought more uniform quality, shorter growing times and a tighter harvest window.

According to Hort Innovation, Australia produced 82,025 tonnes of cauliflower worth $67.4 million at the farm gate in 2024/25, down slightly from the recent peak of 84,893 tonnes and $73.7 million in 2022/23. Crop value has roughly doubled since the mid-2010s as yields and grower consolidation have pushed productivity up. Fresh exports are minimal at 292 tonnes in 2022/23, down from around 800–900 tonnes in the late 2010s, after volumes collapsed as Chinese competition drove prices down in South-East Asian premium markets, as AUSVEG Spotlight 2010 documented. Imports are negligible, so what you buy is almost certainly Australian.
