Gross prices are those realised at the point(s) of valuation where ownership of the commodity is relinquished by the agricultural industry. For example, fruit can be sold into the fresh fruit market, to factories for processing and/or exported.
Gross value for broadacre crops and hay is derived by calculating an average price per tonne for each commodity by weighting pool, trade, and export prices through a mixture of VACP survey, administration data and ABS export data values. This price is then multiplied by quantity.
Gross value for fruit, vegetables is derived by calculating an average price per tonne or kilogram (commodity dependent) using wholesale fresh prices, factory input prices and ABS export data values. This price is then multiplied by quantity.
Gross value for livestock slaughter and other disposals along with livestock products - wool are calculated from the Livestock Products quarterly survey and ABS export data values, adjustments are made to account for the value of wool on skins from sheep and lambs slaughtered as well as live exports.
Remaining commodity data (horticulture and livestock products) are calculated from a mixture of the VACP survey, other ABS collections, non-ABS administrative data sources.
Survey and administrative sources are used to remove marketing and transport costs to calculate a local value.
Example: Calculating gross value for banana production in Australia
