Ann: Elders FY21 Full Year Results, page-26

Unharvested cereal crops (and probably legumes ) now nearly completely unsalvageable over widespread areas , and in regions that matter —
eg. Gunnedah, NSW - very large farms, unharvested wheat completely underwater, with floods the highest in at least over 30 years.
Warwick/ Inglewood/Yelabon , & areas with crops on the Darling Downs - floods significant.
Maybe the biggest floods since the 1970s in Inglewood itself. River peaked early hours this morning but Goondiwindi, St George probably, Texas region won’t flood significantly in the towns but waters still flowing and river levels to rise in the coming days.

Plus it has still been raining.
I’m not sure how widespread over cropping areas eastern seaboard.
Hopefully SA & WA and other parts of NSW and Vic can be good

Certainly any salvage where flooded - every attempt would be made to try and harvest crops if possible.
However crops have already been standing in water for a week in many places, and weeks of wet weather culminating in floods and water flowing through paddocks now and still for days to come .

Not sure what Central Qld is like. But further north and inland Qld was too dry to plant crops in the first place with drought over much of Qld and parts of Northern NSW prior to these early summer huge rain events. Roma has broken known recorded records (150 years) for November rainfall.
