DATA QUALITY

This dataset has been subject to  independent  post-production  validation  and
testing.  Up to eighty tests, most using a sampling  regimen, have been carried
out on the  dataset to ensure its  integrity.  Tests are  carried  out for data
completeness,  correct  spatial  representation,  attribute  accuracy,  logical
consistency,  metadata  completeness and correctness, and where appropriate for
compliance  with  Geoscience  Australia's  GIS data  dictionary.  Although  the
validation procedure has not been subject to rigorous  statistical  analysis it
is  intuitively  estimated  that fewer  than 5 per cent  errors  occur in those
aspects of the data subject to validation.

Errors found in this dataset should be reported to:

Corporate GIS Data Manager
Geoscience Australia
GPO Box 378
Canberra ACT 2601, Australia
Email:  Dmitar.Butrovski@ga.gov.au

Errors  reported  in this way  shall  be  recorded  and  will be  rectified  in
subsequent data releases, if any.
