Australia faces an estimated economic hit of about $13.4 billion as El Niño conditions threaten lower rainfall and disrupt farming outputs. The warnings point to pressures on agricultural production, with potential flow-on effects for food supply and prices.

Across coverage, farmers are described as responding to the forecast weather shift by thinning herds and changing planting plans. The reports say producers are varying rotations and adjusting livestock numbers as they prepare for drier conditions associated with a stronger El Niño pattern. The expected impacts are framed in terms of both direct production losses and wider economic effects.

While outlets differ mainly in wording and the emphasis on economic scale versus food-price or crop impacts, they align on the core message: El Niño-driven rainfall shortfalls increase risk for Australian agriculture. The figures cited are consistently around the $13 billion range, with one report specifying $13.4 billion.
