Wilmar International holds the majority share (75%) in Sugar Australia and New Zealand Sugar in a joint venture with Mackay Sugar Limited (25%). Sugar Australia operates Racecourse Refinery at Mackay, in Queensland, and Yarraville Refinery at Melbourne, in Victoria. New Zealand Sugar operates Chelsea Sugar Refinery at Auckland.

Racecourse Refinery is Australia’s largest and most advanced sugar refinery and produces about 380,000 tonnes of refined sugar each year – the equivalent of 380 million 1kg bags of CSR Sugar. The Mackay refinery commenced production in 1994. It was designed for continuous operation and minimal maintenance shutdowns each year. The refinery adjoins Mackay Sugar’s Racecourse Mill. All of the sugar processed at the refinery is sourced from the Mackay region.

Yarraville Refinery is Australia’s longest-established refinery, having been in operation since 1872. The site produces about 240,000 tonnes of refined sugar each year. A large range of quality packaged sugar is manufactured at the Yarraville refinery, including industrial and retail sugar, liquid sugar, invert sugar, golden syrup, treacle, brown sugar and icing sugar.

Located on the banks of the Waitemata Harbour, the Chelsea Sugar Factory has supplied quality sugar products to homes and businesses across New Zealand since 1884. About 27,000 tonnes of raw sugar is shipped to Chelsea’s front door every six weeks for processing. It is turned into a range of Chelsea products that are packaged on site and distributed throughout New Zealand and the Asia Pacific.
