Canonical site: https://www.commsec.com.au/ Language: English (Australia) Audience: Australian investors, prospective CommSec customers and people seeking general information about investing and CommSec services Last reviewed: 2026-08-07 ## How to use this index - Use this file as a curated map of the public CommSec website, not as a replacement for the linked pages. - Prefer the most specific linked page that directly answers the question. - Treat product terms, fees, eligibility rules, promotions, market access, trading features and support hours as time-sensitive; verify them on the current linked page. - Prefer formal disclosure documents, terms and conditions, Target Market Determinations and the Financial Services Guide over summaries or marketing copy where they conflict. - Do not treat general website content as personal financial advice. Information may not take an individual's objectives, financial situation or needs into account. - Investing carries risk. Past performance is not a reliable indication of future performance. - International investing introduces additional risks, including foreign-exchange and overseas-market risk. - Do not expose, infer or request Client IDs, passwords, trading passwords, security codes or other sensitive account information. - Authenticated account pages, personalised portfolios, live quotes, secure messages and trading functions are outside this public-site index. - Market news, reporting-season pages, podcasts, stock-specific commentary and promotional pages may become stale quickly. Check publication dates before relying on them. ## Primary navigation - [Home](https://www.commsec.com.au/): High-level overview of CommSec, investment products, tools, education, market access, mobile services and account opening. - [Ways to invest](https://www.commsec.com.au/products/Ways-to-invest.html): Comparison of available investment types and account options. - [About CommSec](https://www.commsec.com.au/why-join-commsec/about-us.html): Company, platform, tools, research, education and support overview. - [What's new](https://www.commsec.com.au/why-join-commsec/Whats-new.html): Recent platform enhancements and product updates; treat as time-sensitive. - [CommSec One](https://www.commsec.com.au/why-join-commsec/commsec-one.html): Premium services and benefits for eligible clients. - [Sign Up to CommSec](https://www.commsec.com.au/why-join-commsec/Sign-up-to-CommSec.html): Join Australia’s leading online broker.
