CHESS Replacement Home


On 17 November 2022, ASX published a market announcement detailing the findings from the independent review into the delivery of the CHESS replacement application software. A copy of the independent report can be found here. As a result of this report, and ASX’s own internal assessment, ASX notified the market that it would pause current activities on the project and close the Industry Test Environments (ITE) while we reassess all aspects of the CHESS replacement project.

Therefore, the project documentation previously published within this space has been deactivated from 23 November 2022.

Further planning will be undertaken by ASX to understand and evaluate the solution design options for the replacement of CHESS. Communication on future phases of the project will be shared at the appropriate time. Please refer to the project website here.
