The Burdekin Delta: The Sugar Industry That Feeds the World

The Burdekin Delta, 80 kilometres south of Townsville, is one of the most productive sugar cane growing areas in the world, with the combination of the Burdekin River's irrigation water, the volcanic soils of the delta flats, and the reliable tropical climate producing sugar cane yields per hectare that are among the highest in Australia. The Burdekin sugar district, centred on the towns of Home Hill and Ayr, supplies the mills that process the cane harvest and the bulk terminal at the Bowen harbour that loads sugar for export markets.

The irrigation system that makes Burdekin cane production possible is one of Queensland's most significant agricultural water infrastructure achievements, drawing water from Lake Dalrymple (Burdekin Falls Dam) through a network of irrigation channels that distribute the stored water across the delta's growing areas. The dam, the largest by volume of water stored in Queensland, provides the water security that allows cane production through drought years that would otherwise reduce harvest volumes significantly.

The cane harvesting season, running from June to November, provides the most visible expression of the sugar industry's scale, with the cane harvesters that move through the fields and the cane trains that carry the harvest to the mills operating 24 hours a day during peak harvest periods. The burning of cane trash before harvest, a practice that is being reduced through green harvesting initiatives but that still occurs on some properties, produces the plumes of smoke visible across the delta that mark the harvest season's progress.

Townsville's economic connection to the Burdekin sugar industry, while indirect compared with the direct employment and commercial activity in the delta towns themselves, extends through the supply chain of machinery, chemicals, financial services, and transport that the industry requires and that Townsville, as the regional commercial hub, substantially provides. The sugar industry's regional economic contribution extends well beyond the primary production value in ways that multiply the direct agricultural income through the supply chain and processing sectors.
