Flooding in New South Wales' Lachlan Valley has wiped out crops on several farms, including Myall Park near Forbes. Farmers with income protection policies expect payouts covering the gap between grain value and 75-80% of five-year average income per hectare.
Regional flood losses in NSW reduce local barley, wheat and oat supply, but the scale is local and unlikely to move world prices much. Insurance payouts help sustain farm income rather than change crop volumes.
