The CBA broker portal, explained for brokers.
CommBroker is Commonwealth Bank's third-party portal — the place you go to lodge applications, track SLAs, pull rate sheets, and access training. This guide covers how to log in, what is actually inside, where commission RCTIs live (spoiler: not where you might expect), and how your aggregator statement plugs the reporting gap.
How CommBroker login actually works.
The public portal lives at commbroker.com.au. When you hit the login link, CommBroker redirects out to CBA's third-party single sign-on atsignon.thirdparty.commbank.com.au — an OAuth2 / OpenID Connect identity provider shared across CBA's third-party channels.
You sign in with a User ID (your CAPS ID or Agency Number) and password. A self-service password reset link is available on the sign-on screen. Sessions time out aggressively, so expect to re-auth several times across a busy day — keep your User ID and password manager handy.
What CommBroker surfaces once you are in.
CommBroker bundles deal tracking, policy and pricing reference material, training, and the BCC client-updates program into a single portal. CommBank Alpha — the asset finance broker experience — lives as a separate sign-on with its own user guide.
- Your Applications and Your Loans dashboards for live deal tracking and SLA visibility
- Forms library, interest rate sheets, fees schedules and credit policy documents
- Training Hub with workshops and accreditation resources
- Broker Customer Connect (BCC) program for automated client updates on application progress
- CommBank Alpha asset finance broker portal (separate flow for commercial / asset finance deals)
- Commission and remuneration reporting accessible to the principal or agency contact
Where CBA commission RCTIs really live.
Commission RCTIs and remuneration statements sit behind the CommBroker login under the commissions / remuneration section — but they are typically distributed to the head group or aggregator, not to each broker user individually.
In practice, most authorised representatives never see the raw CBA RCTI. Their upfront and trail for CBA-settled loans arrives via the aggregator's monthly statement (AFG, Connective, Loan Market Group, Finsure, and the rest). If you are a principal or run a head group that receives RCTIs directly from CBA, you will find them in the portal's remuneration area.
What brokers grumble about.
- Slow page loads and the site failing to open are documented in third-party login help indexes — brokers are usually asked to troubleshoot connectivity before raising a ticket.
- Commission and RCTI data is not surfaced to individual broker users in the dashboard — most brokers chase their aggregator or principal to see what CBA actually paid them.
- Many brokers admit they only use CommBroker for the basics (applications and rates) and miss features like Broker Customer Connect because navigation buries them.
You probably don't need to touch CommBroker for commissions at all.
For most Australian brokers, CBA commission data flows into Trail AI automatically via the aggregator monthly statement — AFG, Connective, Loan Market Group, Finsure, and others. There is no separate CommBroker upload required to see your CBA trail, upfront, missing-trail rows, or refinance candidates for CBA-funded loans.
Principals or head groups that receive RCTIs directly from CBA can drop the CommBroker RCTI PDF into Trail AI's single-lender upload. The CBA lender mapping extracts loan-level upfront and trail rows so the per-loan numbers reconcile against what the aggregator sent through.
