CHANGES TO THIS ISSUE

Original estimates for Queensland coal exploration in the December quarter 2010 and March quarter 2011 have been revised as a result of updated information received from survey respondents. Revisions to seasonally adjusted estimates are due to revisions to original estimates as well as the concurrent methodology for deriving seasonal factors.
