Not quite a century @Magneto as they only started including Australia in the 1940s there in those tables. However there has certainly been share trading here in Australia since the 1850s (170 years) and we've had at least one stock exchange here since the late 1850s or early 1860s depending on the source:
According to the National Museum Australia (see here), In the 18 October 1852 issue of the Argus, Edward Khull listed 14 companies in which investors could buy shares, which was the first stock listing in Australia and led to the formation of the Melbourne Brokers Association, which traded from rented space in the Hall of Commerce on Collins Street from 1859. It was Australia’s first stock exchange.
According to Market Index (see here), Australia's first stock exchange was established in Melbourne in 1861. Over the next few decades, additional regional exchanges were established in Sydney (1871), Hobart (1882), Brisbane (1884), Adelaide (1887) and Perth (1889). All exchanges traded independently of each other until 1937 when the Australian Associated Stock Exchanges (AASE) was established, bringing with it uniformed listing and commission rules. The following year, in 1938, the first official share price index was published.
So you could be right about the last century, it's just that those tables only show Australia for the past 8 decades.
Interesting that Australia outperformed the US in four out of those eight decades (50% of them) - it hasn't felt like that since I've been in the game (almost 30 years) - it has always felt like the USA was thrashing us - which has a lot to do with big Tech of course which has seriously outperformed in recent decades.
