Expressions of interest for the purchase of Lawson Grains have been coming in non-stop, selling agent Danny Thomas, of LAWD, said.

"There's been extraordinary interest, I've had something like 200 inquiries [in about four weeks]," he said.

The sale includes the Albury-based management and technical team of about 55 people as well as its machinery fleet and 10 aggregated farms.

Mr Thomas said there had been inquiries "across the board, [from] every sector of the market".

Everyone from farming residents to international investors and agricultural rich-listers have expressed interest in the company's individual properties or combined portfolio.

Initially Macquarie Bank expressed a preference for the business and land portfolio to be sold as one, but there has been strong interest from individuals and syndicates for sole or grouped properties.

"If it makes financial sense they're happy to do a break up," he said.

"All local interest is welcome, if you've got your eye on a particular part of the portfolio which appeals to you, please express interest."

Mr Thomas was unable to comment on the exact price expectations for the business and assets, but market speculation puts the sale price at about $550 million or more.

The 10-year-old business produced more than 250,000 tonnes of cereal, pulse and oilseed crops last year.

Mr Thomas said the business continued to be profitable but was being sold as the investment fund backing it was due to expire having reached the end of its fund life. Macquarie Infrastructure and Real Assets through Lawson Grains acquired more than 70 properties to create its 10 farms.

Their portfolio consists of 7214 arable hectares in Northern NSW, 10,524 arable hectares in Central NSW, 18094 arable hectares in Southern NSW, 22,187 arable hectares in Northern NSW and 31,322 in Southern WA. First round expressions of interest close on April 29.
