RELEVANCE
Final estimates from the 2017–18 Rural Agricultural and Commodities Survey (REACS) will be presented in four publications:

Agricultural Commodities, Australia (cat. no. 7121.0) contains detailed statistics on land use, crop and horticultural area and production, livestock numbers and farm management and demographic information. The publication presents data on a national, state and territory and sub-state level, including Australian Statistical Geography Standard (ASGS) Statistical Area 4 (SA4) and Natural Resource Management (NRM) regions.

Water Use on Australian Farms (cat. no. 4618.0) contains detailed statistics on agricultural water use and sources of water, including details of pastures and crops irrigated, expense of irrigation and volume of water applied. The publication presents data on a national, state and territory and sub-state level, including ASGS SA4, NRM regions and the Murray-Darling Basin region.

Value of Agricultural Commodities Produced, Australia (cat. no. 7503.0) presents value of production statistics. It contains detailed statistics on the gross and local values of crops, livestock slaughters and disposals, and livestock products .This publication presents data on a national, state and territory and sub-state level, including ASGS SA4 and NRM regions.

Gross Value of Irrigated Agricultural Production (cat. no. 4610.0.55.008) presents the gross value of agricultural commodities that are produced with the assistance of irrigation. The publication presents data on a national, state and territory basis, NRM region and Murray-Darling Basin region.

TIMELINESS
Agricultural Commodities, Australia (cat. no. 7121.0), Value of Agricultural Commodities Produced, Australia (cat. no. 7503.0) and Water Use on Australian Farms (cat. no. 4618.0) will be published in April 2019 and Gross Value of Irrigated Agricultural Production (cat. no. 4610.0.55.008) will be published in May 2019.

ACCURACY
Data from the 2017-18 survey are based on a response rate of 77.1% and have been extensively quality assured. The resultant estimates have been checked against earlier years' estimates and relevant other sources, to ensure the accuracy of estimates produced.

All estimates in this publication are subject to sampling error. For more information about these errors, refer to the Explanatory Notes within this release.

COHERENCE
The survey was conducted using a frame based on the Australian Business Register (ABR). This is the same as the frame used for the 2015-16 Agricultural Census and for annual agricultural surveys and agricultural conducted since 2005-06.

For the purposes of this collection a business (statistical unit) is identified as undertaking agricultural activity if any of the primary or secondary productive activities of that business fall with the Agriculture Subdivision (Subdivision 01) as defined by the 2006 edition of the Australian and New Zealand Standard Industrial Classification (ANZSIC). For more information, please refer to Australian and New Zealand Standard Industrial Classification (ANZSIC), 2006 (cat. no. 1292.0).

The scope of the survey was all agricultural businesses with an EVAO of $40,000 or greater. This is a change from previous surveys, where a scope of EVAO of $5,000 or greater was used, and is a continuation of the scope used in the 2015-16 Agricultural Census. The scope better aligns this collection with contemporary definitions of an agricultural business and reduces the overall reporting load for smaller agricultural businesses. It is proposed that only agricultural businesses with an EVAO of $40,000 or greater will be in scope for ABS rural environmental and agricultural commodity collections in the future. For more information about EVAO, refer to the Explanatory Notes within this release.

As a result of the change in scope, the estimates from the survey will not be directly comparable to previous published survey outputs. To address this, additional estimates have been produced from a number of rural environment and agricultural commodity collections from 2010-11 to 2014-15 using an EVAO of $40,000 or greater. These estimates are now available at the national, state/territory levels and sub-state levels on the ABS website.


INTERPRETABILITY
The survey and the Agricultural Census provide a broad range of data about Australian agricultural commodities through a suite of standard products or as data customised for individual requirements. Time series data are available for some estimates that were collected through previous surveys/censuses. Detailed explanatory notes are provided with each publication to assist users in determining and specifying their data requirements and to understand the concepts underlying the data.

ACCESSIBILITY
An extensive range of data is available from a variety of agriculture-based collections on the ABS website.
