A2P SMS regulations in Australia.
Compliance with ACMA rules and sender-ID registration.
A2P SMS to Australia is regulated by the Australian Communications and Media Authority (ACMA). Alphanumeric sender IDs must be in the ACMA SMS Sender ID Register; since 1 July 2026, unregistered IDs are shown as "Unverified". Allow 5-10 business days. Spam Act 2003 + Privacy Act 1988 enforced. BroadNet carries this traffic over direct operator connections.
Who regulates A2P SMS in Australia?
Application-to-person messaging to Australia is overseen by the Australian Communications and Media Authority (ACMA), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Australia over direct operator connections — Telstra, Optus and Vodafone Australia — rather than through resold or grey routes, so the sender ID, the delivery receipt and the audit trail all come back from the licensed path.
- Telecoms regulator: Australian Communications and Media Authority (ACMA).
- Direct operator routes: Telstra, Optus and Vodafone Australia.
- Sender-ID registration: mandatory in the ACMA SMS Sender ID Register (Industry Standard 2025).
- Typical lead time: 5-10 business days.
Sender ID registration in Australia
Since 1 July 2026, every branded (alphanumeric) sender ID sent to Australian mobiles must be in the ACMA SMS Sender ID Register, set up by the Telecommunications (SMS Sender ID Register) Industry Standard 2025 and the SMS Sender ID Register Determination 2025. Unregistered IDs are replaced with "Unverified" on the handset. Registration goes through a participating or certified telco or message provider, with checks on the organisation and its authorised representative, and the ID must match the organisation's name or trademark. Plan 5-10 business days and register before you need the route, not during a launch.
- Lead time: 5-10 business days.
- Registered through a participating or certified provider; BroadNet coordinates it during onboarding.
- Unregistered IDs are shown as "Unverified" since 1 July 2026.
- Time to production: Live in 5–15 business days from test-access request to production.
Consent and content rules
Spam Act 2003 + Privacy Act 1988 enforced. The SMS Sender ID Register Industry Standard and Determination 2025 require sender-ID registration. Transactional messages — one-time passcodes, delivery and account alerts — are treated differently from marketing, but the distinction is decided by the content of the message rather than by how the campaign is labelled.
- SMS Sender ID Register: mandatory under the Telecommunications (SMS Sender ID Register) Industry Standard 2025.
- Privacy Act + Spam Act: Privacy Act 1988 and Spam Act 2003 enforced.
- Opt-out required: Opt-out language on every promotional SMS.
What this means for your integration
Practically, three things decide whether traffic to Australia performs: a registered sender ID on an ACMA-licensed route, a consent and opt-out record you can evidence, and message content that matches the category it was registered under. BroadNet's compliance engine checks each submission against the Australia ruleset before it reaches the operator, so a non-compliant send is rejected back to you rather than filtered silently downstream — which is the difference between a fixable error and traffic that quietly disappears.
- Every message returns a delivery receipt (DLR); BroadNet does not publish per-country delivery percentages.
- Indicative list pricing: USD 0.035 – 0.06 per message.
- Addressable mobile base: 32M subscribers.
- Privacy Act + Spam Act: Privacy Act 1988 and Spam Act 2003 enforced.
