Australia: 60–70% of Riverland citrus downgraded by extreme weather

What we know

In the Riverland — a region of South Australia stretching along the Murray River — extreme weather conditions during the current season have downgraded 60–70% of locally grown oranges and mandarins, according to ABC News.

Two distinct factors contributed to the damage: record heat waves during summer and an unusually cold, wet winter.

Mandarin supply has fallen by approximately 20% due to a combination of late flowering and record heat, according to Fabio Spiniello of Venus Citrus, a packing company.

Harvest windows severely reduced

Mark Doecke, chairman of Citrus SA and a citrus producer at Sunlands, explains that pickers can only begin around noon to avoid harvesting below 12°C in humid conditions, which leaves visible marks on fruit within three or four days.

Workdays end at 4 p.m., reducing shifts to around four hours and cutting seasonal worker income.

Four sorting classes at Venus Citrus

Approximately 50 Riverland producers deliver their fruit to Venus Citrus's packing facility in Loxton. Citrus is sorted into four classes, ranging from 'premium' to 'processing' (reserved for juice and purees).

Winds during December and January created spots on oranges when they were golf-ball sized; these spots widen as the fruit grows, contributing to downgrading.

Varieties hit unevenly

Navel oranges — a variety characterized by a small secondary fruit at the apex resembling a navel, typically seedless — show increased skin fragility due to excess rain. The Washington navel subvariety is particularly affected, according to Spiniello.

By contrast, Cara Cara oranges performed excellently this season, according to Spiniello.

Producers who protect their crops with netting are more likely to achieve premium classification for their fruit.

Local retailers adapt

Ryan Oakley, owner of Mason's Fruit and Veg in Barmera, is sourcing more citrus from other Australian states to compensate for local supply shortages while maintaining affordable prices.

He notes that local fruit remains available and edible despite cosmetic flaws.

What remains uncertain

The precise economic impact of these downgrades for Riverland producers has not been quantified in available sources. The exact nature of Citrus SA as an organization and the specific characteristics of the Cara Cara variety lack verified definitions at time of publication.
