RELEVANCE
Wheat Use and Stocks, Australia (cat. no. 7307.0) presents data of wheat grain stocks and use for selected manufacturing and agricultural businesses, licensed exporters and bulk grain handlers. These estimates are compiled from various surveys conducted by the ABS, including the periodic Grain (wheat) Handlers Stocks Survey, monthly Wheat Use Survey, the monthly Wheat Export Sales Survey, and administrative data relating to wheat grain exports.
The Wheat Use Survey is a monthly survey of selected wheat grain users, including selected manufacturers and animal feedlot operators. Data are collected on the basis of the state where the wheat is used, stored and contracted for future use. The data are released at state and Australian levels.
The Wheat Export Sales Survey is a monthly survey of wheat exporters' contracts for future wheat grain exports. Data are collected on the basis of the state where the wheat grain is sourced, and then aggregated to derive Australian totals.
The Grain Handlers Stocks Survey is a monthly survey of the major bulk grain handling businesses in Australia to collect data on stocks of grain and quality grades.
Data relating to the export of wheat are compiled from information submitted by exporters, or their agents, to the Australian Customs Service (ACS). Statistics are compiled for state and national totals.
The wheat surveys are undertaken on behalf of the Department of Agriculture, Fisheries and Forestry to assist the wheat industry. The Australian Bureau of Agricultural and Resource Economics (ABARE) uses these data to compile a regular report on uncommitted wheat stocks within the Australian economy.
