What Is The ASX?
The Australian Securities Exchange is a public company headquartered in Sydney that operates the main stock exchange in Australia. It was formed in 1987 by merging six state‑based stock exchanges and later combined with the Sydney Futures Exchange in 2006.
- ASX Group acts as a market operator, clearing house, and payments system facilitator, providing infrastructure for trading, clearing, and settlement.
- It offers markets in equities, fixed income, derivatives, commodities, and energy, making it a one‑stop shop for many Australian investors.
- Investopedia describes the ASX as a fully functioning securities exchange that also provides educational materials to retail investors.

Brief History Of The Australian Securities Exchange
The ASX in its current form is the result of decades of consolidation and modernisation in the Australian capital markets.
- In 1987, Australia amalgamated six independent state‑based stock exchanges (Sydney, Melbourne, Brisbane, Adelaide, Hobart, and Perth) into the Australian Stock Exchange Limited.
- In 1998, ASX demutualised and became one of the first exchanges in the world to list its own shares on its market.
- In 2006, the Australian Stock Exchange merged with the Sydney Futures Exchange to create the Australian Securities Exchange, commonly known as ASX Limited.

ASX Trading Hours And Market Phases
Knowing when the ASX is open is crucial if you’re placing trades directly or via an online broker.
- Normal trading hours on the ASX are 10:00 a.m. to 4:00 p.m. (Sydney time) on business days, excluding public holidays.
- Before normal trading, there is a pre‑open phase (7:00 a.m. to around 9:59 a.m.) where orders can be entered but not executed.
- After the close, there is a closing auction and then an adjustment period where existing orders can be modified or cancelled but no new trades occur.
MarketIndex provides a detailed table of ASX market phases (pre‑open, auction, normal trading, pre‑CSPA, adjust, purge, and maintenance), which you can reference at ASX trading hours – Market Index. Basic hours and an investor‑friendly explanation are also available via brokerage help pages like CommSec’s guide to ASX open and close times.
Regulation And Oversight
The ASX operates within a tightly regulated framework to protect investors and ensure market integrity.
- The Australian Securities & Investments Commission (ASIC) oversees real‑time trading on domestic licensed markets and supervises brokers’ conduct.
- ASX Compliance, a subsidiary of ASX, monitors listed companies’ adherence to ASX listing rules.
- The Reserve Bank of Australia (RBA) supervises ASX’s clearing and settlement facilities to protect financial‑system stability.
