The largest factory managed by Mackay Sugar, Marian Mill is situated approximately 30 minutes from the CBD in the regional town of Marian – nestled amongst some of the highest yielding sugar cane land in our region. On average, Marian Mill produces approximately 280,000 tonnes of raw sugar, 70,000 tonnes of molasses and exports 6,900 MW hours of electricity.

Marian Mill was first built in 1885, but closed after a few years. The Marian Central Mill Co Ltd erected a new mill in 1894 under the Sugar Guarantee Act, and the first crushing took place in 1895. In 1966, the shareholders of Marian Central Mill Co Ltd voted to sell the assets and liabilities of that company to the cane farmers supplying the mill, who formed the Marian Mill Co-operative Society Limited.

In 1988, Marian Mill, together with Cattle Creek, Farleigh, North Eton and Racecourse mills, amalgamated and purchased Pleystowe Mill to form the Mackay Sugar Co-operative Association Limited.

A unique feature is the mural on the Engineering shed depicting a cane fire – rarely seen these days as most cane is cut green. Access is restricted but easily visible from the road. You will pass by the Marian Mill just before you reach Melba House.
