RELEVANCE
Final estimates from the Vineyards 2015 collection will be presented in Vineyards, Australia (cat. no. 1329.0.55.002). This publication contains detailed statistics on the Australian viticulture industry and presents data on a national, state and territory basis, with data also available for Australian Geographical Indication (GI) regions.
The Vineyards 2015 collection was undertaken as a census. Detailed information was collected for 40 of the major wine grape varieties, including total area under vine, bearing area, area not yet bearing, area of vines removed, and production of grapes for winemaking or distillation. In addition, information was collected on area of grapes left on the vine or dropped to the ground at maturity, total area of wine grapes watered and volume of water used, sources of water and watering methods.
The Vineyards 2015 collection was run on behalf of the Australian Grape and Wine Authority (AGWA). The results of this survey will be used to measure the viticulture industry's activity throughout Australia and to support decision making, research and analysis by grape and wine industry policy makers, researchers and the community.
TIMELINESS
Vineyards, Australia (cat. no. 1329.0.55.002) will be published within 4 months of the end of the reference period.
ACCURACY
Data from the Vineyards 2015 collection are based on a response rate of 87% and have been extensively quality assured. The resultant estimates have been checked against earlier years' estimates and relevant other sources, including contact with data providers and industry bodies, 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.
