Australian Stock Exchange (ASX)

The Australian Stock Exchange Limited (ASX) operates Australia's national exchange for equities, derivatives, and fixed interest securities such as bonds. The exchange also provides comprehensive market information and data to a wide range of traders, brokers, and commissions.

History of the Australian Stock Exchange

The history of the Australian Stock Exchange starts with the six capital city exchanges that were established in Adelaide (1887), Brisbane (1884), Melbourne (1884), Hobart (1882), Perth (1889), and Sydney (1871).  Several smaller provincial exchanges were established to cater to the needs of the large number of mining companies in existence at the turn of the 20th Century.

From 1903 until 1937, these state stock exchanges began meeting on an informal basis.  By 1936, Sydney had taken the lead in formalizing the association, and in 1937 the Australian Associated Stock Exchanges (AASE) was established.  The formation of the AASE laid the groundwork for listing of companies, brokerage, and the operating rules of the stockbrokers and their firms.

On April 1, 1987, the Australian Parliament passed legislation forming the Australian Stock Exchange Limited (ASX).  Forming a national stock exchange brought together the six independent stock exchanges operating in the capital cities.
