1 This publication presents estimates from the Australian Bureau of Statistics' (ABS) 2009 Vineyards Survey.
2 The Vineyards Survey was conducted on behalf of the Grape and Wine Research and Development Corporation (GWRDC). The main user of this information is the Australian wine industry's Statistics Working Group (SWG), which is made up of representatives of industry peak bodies, and its role is to represent the views of the industry on statistical matters.
3 In contrast to previous years, the 2009 Vineyards collection was undertaken using a survey methodology and collected information on the major wine grape varieties only. Previous collections were conducted as censuses of all in-scope vineyards, and included all significant varieties, as well as table, drying and other grapes. Vineyards irrigation information was also excluded from the 2009 survey. Estimates of area, production and yield for the main wine grape varieties are presented in the publication for Australia and states and territories, and are available at sub-state regions in attached datacubes. The sub-state regions are based on Australian Geographical Indication (GI) Zones and Regions.
4 GI Zones and Regions are official descriptions of Australian wine zones, regions and sub-regions which are defined in the Australian Wine and Brandy Corporation Act, 1980. For more detail on Australian GIs, including maps of zones and regions, see the Australian Wine and Brandy Corporation website, http://www.wineaustralia.com/australia.
5 The derived zones published by the ABS are based on those defined by the Australian Wine and Brandy Corporation. See the Appendix for a list of derived zones for this publication.
6 This publication presents the final Vineyards estimates for 2008-09, including area, production, and yield for wine grapes and major wine grape varietals.
7 Where figures have been rounded, discrepancies may occur between sums of the component items and totals.
SCOPE AND COVERAGE
8 The scope of the 2009 Vineyards Survey was agricultural businesses recorded on the ABS' Business Register (ABSBR) above a minimum size cut-off. The ABSBR is based on the Australian Business Register (ABR) which is administered and maintained by the Australian Taxation Office (ATO). This business based frame replaces the land based frame previously used for the Vineyards collection.
9 A minimum size cut-off of $5,000 was applied to determine whether a business was in-scope for the Vineyards 2009 Survey, as well as being identified on the ABSBR as a wine grape grower/vineyard through survey feedback or from Australian and New Zealand Standard Industrial Classification (ANZSIC) information. The measure of size was based on either the ABS' Estimated Value of Agricultural Operations (EVAO) or a derived value based on Business Activity Statement (BAS) turnover.
10 While the ABSBR does not include all agricultural businesses in Australia, it provides improved coverage from the previous ABS-maintained Agricultural Survey frame, since most businesses and organisations in Australia need to obtain an Australian Business Number (ABN) from the ATO for their business operations. The ABR-based register also provides more up-to-date coverage as it excludes agricultural businesses with cancelled ABNs and incorporates regularly updated information on agricultural businesses from the ATO.
11 For the 2009 Vineyards Survey, a sample of approximately 4,600 businesses was selected from an in-scope population of approximately 10,000 businesses. The response rate was 89%.
12 Vineyards statistics relate to the year in which the harvest occurred.
13 Tasmanian data are collected in partnership with the Department of Primary Industries, Parks, Water and Environment. The scope of the data collected is the same as for other states.
RELIABILITY OF ESTIMATES (SAMPLE ERROR)
14 The estimates in this publication are based on information obtained from a sample drawn from the total business population in scope of the collection, and are subject to sampling variability; that is, they may differ from the figures that would have been produced if all businesses had been included in the survey. One measure of the likely difference is given by the standard error (SE) which indicates the extent to which an estimate might vary by chance because only a sample was taken. There are about two chances in three that a sample estimate will differ by less than one SE from the figure that would have been obtained if all businesses had responded, and about nineteen chances in twenty that the difference will be less than two SEs.
15 In this publication, sampling variability of the estimates is measured by the relative standard error (RSE) which is obtained by expressing the SE as a percentage of the estimate to which it refers.
16 Unless otherwise annotated, published national estimates have RSEs less than 5%. For some states with limited production of certain commodities, RSEs are greater than 10%. Estimates that have an estimated RSE between 10% and 25% are annotated with the symbol '^'. These estimates should be used with caution as they are subject to sampling variability too high for some purposes. Estimates with an RSE between 25% and 50% are annotated with the symbol '*', indicating that the estimate should be used with caution as it is subject to sampling variability too high for most practical purposes. Estimates with an RSE greater than 50% are annotated with the symbol '**' indicating that the sampling variability causes the estimates to be considered too unreliable for general use. Separate indication of the RSEs of all estimates is available on request.

18 ABS publications draw extensively on information provided freely by individuals, businesses, governments and other organisations. Their continued cooperation is very much appreciated. Without it, the wide range of statistics published by the ABS would not be available. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.
