This study examines changes in segment reporting in Australia following the adoption of the international accounting standard, IFRS 8 Operating Segments. We analyse segment disclosures of the top 200 companies listed on the Australian Stock Exchange in their pre- and post-adoption of AASB 8, the equivalent Australian standard to IFRS 8. Our findings indicate that the number of reportable segments and the extent of disclosure have increased post-adoption of AASB 8. Contrary to expectations, however, there is very little change in the identification of reportable segments. Companies, in general, have managed to retain their segment reporting formats and disclosures from the pre-AASB 8 period.
