On 29 April 2011, the Australian Securities and Investments Commission (ASIC) announced the exchange market integrity rules. This follows the Australian Government’s announcement in March 2010 of its support for competition between exchange markets for trading in Australian Securities Exchange (ASX) listed products in Australia, and its in-principle support for granting an Australian market licence to Chi-X Australia Pty Ltd that intends to offer trading services in competition with the ASX. The Regulation Impact Statement was prepared by ASIC and has been assessed as adequate by the Office of Best Practice Regulation.
