Bulk grain handler Viterra has already outturned three quarters of the 5.6 million tonnes of grain delivered by South Australian growers during the 2023/24 harvest.
Of the 4.3mt outturned, 4mt was for export and 320,000t for domestic purposes.
Viterra Supply Chain general manager Derek Robjohns said moving the grain early had enabled them to access markets when demand was at its highest before the Northern Hemisphere harvest began.
Mr Robjohns said employees had been busy working to meet demand at the company's six port terminals.
"We have now loaded over 1 million tonnes onto vessels at each of our Port Lincoln and Outer Harbor terminals," he said.
"We are also exporting lentils at a record pace from our Wallaroo port to meet the needs of buyers, where we are seeing strong demand after we received the commodity at the site for the first time this season."
There is still some late grain deliveries trickling in, with the handler receiving 23,000 tonnes during March.
Viterra also recently concluded its regional postharvest meetings, bringing together employees and grower representatives from across its Western, Central and Eastern regions.
Plans for the 2024/25 harvest were discussed by attendees, with key topics including Viterra's segregation plan.
Viterra Operations general manager Gavin Cavanagh said the meetings provided an effective way of gathering feedback from those closest to the harvest.
"This allows us to understand what changes would work best for both employees and growers, while also keeping everyone informed about our business activities and market developments," he said.
