The exchange first opened in 1997 as the Australian property exempt market before receiving a stock exchange license in August 2004. In November 2015, the exchange was renamed the Sydney Stock Exchange.^[1] To promote Sydney and Australia as a leading financial centre, and allow the listees to be identified as being listed on a major city's exchange, the exchange became known as the Sydney Stock Exchange (SSX). The exchange is an observer member of the Federation of Euro-Asian Stock Exchanges.

The SSX's corporate logo consists of a black background with multiple off-centre red circles.
