Papaya (Carica papaya) is a fast-growing tropical fruit tree native to Central America, now cultivated throughout the tropics and subtropics. The fruit is large and pear-shaped, with bright orange or red flesh when ripe, containing a central cavity filled with small black seeds.
Ripe papaya is eaten fresh as a breakfast fruit, in fruit salads, or blended into smoothies. Green (unripe) papaya is used as a vegetable, most famously in Thai green papaya salad (som tam). The fruit also contains papain, a protein-digesting enzyme used commercially as a meat tenderiser and in digestive supplements.
In Australia, papayas are grown commercially in Queensland and the Northern Territory. Two main types are sold: the larger ‘papaya’ (or pawpaw, as it’s often called in Australia) with yellow-orange flesh, and the smaller, sweeter ‘red papaya’. Both are widely available in supermarkets year-round from tropical growing regions.
How it's produced
Papayas are grown on small, fast-growing trees that begin producing fruit within 6–12 months of planting — one of the fastest turnarounds of any tree fruit. The trees are relatively short-lived and are typically replanted every 3–4 years as productivity declines.
Commercial plantations are found throughout tropical regions, with India, Brazil, Indonesia, and Mexico being the largest producers. The trees need consistent warmth, ample water, and well-drained soil. They’re vulnerable to papaya ringspot virus, which has devastated plantations in some regions and led to the development of genetically modified virus-resistant varieties, notably in Hawaii. In Australia, papayas are grown conventionally in north Queensland, often under netting to protect from fruit fly.
