CommSec Review (2026):
Fees, CHESS sponsorship, and who it fits
CommSec is Australia’s largest online broker, backed by Commonwealth Bank. The core question isn’t whether it’s reputable — it is. It’s whether the per-trade fee structure and full-platform complexity make sense for your situation, or whether CommSec Pocket, Stake, or SelfWealth serves you better.

TL;DR
- Australian investors who want CHESS-sponsored ASX ownership.
- Those who value a bank-backed, regulated brokerage environment.
- Larger, less frequent trades where per-trade fees are proportionally small.
- Investors who also bank with Commonwealth Bank.
- $10–$19.95 flat fees that bite hard on small, frequent contributions.
- Limited international market access on the standard platform.
- CommSec Pocket’s five-ETF constraint — flexibility-limited for growing portfolios.
- Cheaper flat-fee alternatives (Stake, SelfWealth) for regular ASX investing.
What is CommSec?
CommSec (Commonwealth Securities) is the brokerage arm of Commonwealth Bank of Australia — the country’s largest bank. It launched in 1995 and remains the highest-volume retail broker in Australia by accounts and trades executed.
- ASX shares, ETFs, mFunds, and warrants.
- CHESS-sponsored — you hold a HIN and direct legal ownership.
- Full research suite: broker reports, company announcements, market data.
- Integrated CBA banking — settlement via linked CommBank account.
- Simplified ETF-only app for beginners.
- Five themed ETF options (global, Australian, sustainable, etc.).
- $2 per trade under $1,000 — lowest entry point.
- No HIN — holdings held in a nominee/custodian structure.
CommSec fee breakdown by trade size
CommSec charges per-trade brokerage — not a subscription or percentage-only model. The structure rewards larger, less frequent trades. Small recurring contributions feel the fee drag most.
| Trade size (AUD) | Standard brokerage | CommSec Pocket |
|---|---|---|
| Up to $1,000 | $10.00 | $2.00 |
| $1,000.01 – $10,000 | $19.95 | $11.00 |
| $10,000.01 – $25,000 | 0.12% (min $29.95) | N/A |
| Over $25,000 | 0.11% | N/A |
- Monthly $500 contributions: $10 fee = 2% per trade.
- That 2% must be recovered before your investment returns anything.
- At this scale, Stake ($3 flat) or SelfWealth ($9.50 flat) are cheaper.
- Quarterly lump-sum contributions of $5,000+.
- At $5,000, $19.95 = 0.4% — manageable with a long-run mindset.
- Larger portfolios consolidating fewer, bigger trades benefit most.
CHESS sponsorship: what it means and why it matters
Not all Australian brokers hold your shares the same way. CHESS sponsorship is the traditional model — you have direct, named legal ownership. It is a meaningful structural difference.
- You receive a Holder Identification Number (HIN).
- Shares registered in your name on the ASX CHESS subregister.
- Ownership is independent of the broker — if CommSec fails, your shares are still yours.
- Transfer to a new broker is straightforward via HIN transfer.
- Shares held in a pooled account in the broker’s name.
- You are the beneficial owner, but not the registered holder.
- If the broker fails, recovery is more complex.
- No HIN — transfers require selling and repurchasing.
What you can trade on CommSec
CommSec’s full platform is comprehensive for ASX-listed securities. Its international coverage is functional but secondary — built on a white-labelled IBKR infrastructure rather than native CommSec infrastructure.
| Asset / Market | Available | Notes |
|---|---|---|
| ASX shares | Yes | Full ASX coverage, CHESS-sponsored |
| ASX ETFs | Yes | Full catalogue — Vanguard, iShares, BetaShares, and more |
| mFunds (unlisted managed funds) | Yes | Direct fund access via ASX mFunds settlement |
| US and international shares | Yes (separate platform) | Via CommSec International — powered by IBKR |
| Fractional shares | No | Full-share purchases only on the main platform |
| Margin lending | Yes | CommSec Margin Loan — separate application required |
| Crypto | No | Not offered via CommSec |
Who CommSec fits — and who it doesn’t
- ASX-focused long-term investors who prioritise CHESS sponsorship.
- Investors banking with CBA who want integrated settlement.
- Larger, less frequent lump-sum investors (quarterly or bigger).
- Investors who want access to broker research and mFunds alongside ETFs.
- Regular small contributors: $10 per trade is a high hurdle below $1,000.
- Investors wanting low-cost US market access as a primary focus.
- Those who want fractional shares for dollar-cost averaging into high-priced stocks.
- Beginners who only need 1–3 ETFs and can use CommSec Pocket — or Pearler at lower fees.
Stake charges $3 per ASX trade (or $0 on US stocks). SelfWealth charges $9.50 flat regardless of size. For investors making regular $500–$2,000 contributions monthly, both undercut CommSec’s standard brokerage — and still offer CHESS sponsorship for ASX holdings.
CommSec’s edge is institutional trust, research depth, and the CBA integration. If those matter less than cost, comparison shopping is warranted.
Ready to open an account?
CommSec suits ASX-focused, buy-and-hold investors who value CHESS sponsorship and CBA integration. If cost per trade is your priority, compare with Stake and SelfWealth first.

Frequently asked questions
Is CommSec good for long-term investing?
Yes, for ASX-focused buy-and-hold investors. CHESS sponsorship gives you direct ownership of your shares, and the platform is backed by Commonwealth Bank. The main drawbacks are per-trade fees that add up on small, frequent contributions, and limited international access compared to Stake or Interactive Brokers.
What are CommSec’s fees for buying ETFs?
Standard brokerage: $10.00 for trades up to $1,000; $19.95 for $1,000–$10,000; 0.12% (min $29.95) for $10,000–$25,000; 0.11% above $25,000. CommSec Pocket charges $2 for trades under $1,000 and $11 for larger amounts, but limits you to five pre-selected themed ETFs.
What is CHESS sponsorship and does CommSec offer it?
CHESS (Clearing House Electronic Subregister System) sponsorship means your ASX shareholdings are registered in your name under a Holder Identification Number (HIN) — not pooled in a nominee account. CommSec’s full platform is CHESS-sponsored, giving you direct legal ownership. CommSec Pocket uses a custodian model instead.
What is CommSec Pocket?
CommSec Pocket is a simplified ETF investing app targeting beginners. It offers five themed ETF options (global 100, Australian top 200, sustainable leaders, and others) at $2 per trade up to $1,000. It is low-friction for first-time investors but lacks the flexibility of the full CommSec platform or competitors like Pearler.
When is Stake or SelfWealth a better choice than CommSec?
Stake charges $3 per ASX trade and SelfWealth charges $9.50 flat — both undercut CommSec’s standard brokerage for smaller and medium-sized contributions. If you are making regular monthly investments below $5,000 and do not need CommSec’s research or CBA integration, comparing on per-trade cost is worthwhile. Both Stake and SelfWealth also offer CHESS sponsorship for ASX holdings.
