The reference period for 2001, 2006 and 2011 was the year ending 30 June, unless otherwise indicated.
The scope of the 2001, 2006 and 2011 Agricultural Censuses was agricultural businesses with an Estimated Value of Agricultural Operations of $5,000 or more.
In 2005-06, the ABS moved to a new frame sourced from the Australian Taxation Office's Australian Business Register (ABR). In addition to the change in frame, there have been changes in methodologies used for determining whether agricultural businesses are 'in scope' of the collection and in some of the ways the data are complied. The key implication of this strategy is that data from 2005-06 is not exactly comparable with earlier data.
Detailed information on the impact of the change can be found in Agricultural Commodities, Australia, 2005-06 (cat. no. 7121.0).
Individuals, businesses, governments and other organisations freely provide information from which ABS publications are drawn. Their continued cooperation is very much appreciated; without it, the wide range of statistics published by the ABS would not be available for general use by the community. Information received by the ABS is treated in strict confidence as required by the Census and Statistics Act 1905.
