Australian Communications and Media Authority (ACMA) regulates A2P messaging and sender-ID registration.

What OTP delivery looks like in Australia.
Latency profile, peak-hour behaviour, recommended fallback chain, and the fraud signals our firewall watches in-market.
Typical latency window
Median 2.8 s with a 95th-percentile inside 8 seconds across operator-direct binds. Two-shot delivery confirmed by DLR.
Peak-hour behaviour
Operator throughput holds steady through local business peaks; throttling kicks in only during outlier mass-send events. BroadNet load-shapes per-MNO to avoid firewall blocks.
Fallback chain
Recommended fallback: Voice OTP after 30s no-delivery. WhatsApp available as an additional channel.
Fraud signals we watch
Watch for SIM-swap fraud on banking flows and for marketing senders that drift outside the registered traffic class.
What you can — and can't — send.
Opt-in, opt-out, quiet hours, content restrictions, and the penalty regime for the Australia market.
Opt-in
Spam Act / equivalent requires inferred or express consent, with the source of consent logged and reviewable.
Opt-out
STOP keyword and clearly stated unsubscribe required on every marketing send. Honoured within 5 business days at most.
Quiet hours
We have not found a regulator-published time-of-day window for promotional SMS in this market. Agree sending hours with the operator and schedule promotional sends for the recipient's local daytime; transactional traffic runs 24/7.
Content restrictions
Misleading-sender provisions apply; sender-ID brand must match the registered identity. Gambling and adult content require licence evidence.
Regulator penalties
ACMA can issue infringement notices and pursue civil penalties — typically scaled per breach and per recipient.
Termination,
network by network.
The route status column shows how each operator is reached — a direct BroadNet bind or a labelled partner route. No grey-route exposure. Route grades are indicative planning guides, not live measurements.
| Operator | MCC-MNC | Route status | Grade | A2P rate (typ.) |
|---|---|---|---|---|
| Telstra | 505-01 | Direct | A+ | USD 0.0506 |
| Optus | 505-02 | Direct | A+ | USD 0.0483 |
| Vodafone Australia | 505-03 | Direct | A+ | USD 0.046 |
Rates shown are typical pay-as-you-go for transactional traffic. Promotional traffic is priced separately, and volume tiers reduce both. See the rate-card section below for the full ladder.

Buyer questions about Australia.
The questions BroadNet's sales engineers field every week from teams shipping into this market.
What's the typical sender-ID approval time with ACMA in Australia?
Typical lead time: 5-10 business days. BroadNet confirms the current sender-ID requirements and documents during onboarding.
Are BroadNet's routes to Australia operator-direct?
Yes — every operator on the public coverage table is a direct A2P bind. No aggregator hops, no grey-route exposure. Route grades are indicative planning guides, not live measurements.
Can I send marketing SMS in Australia without prior consent?
No. Verifiable opt-in is required across every market BroadNet supports, with the consent source, timestamp, and channel logged. Transactional OTP and account-level alerts are exempt from marketing-consent rules.
Which channels do you support for Australia — SMS only, or also WhatsApp and Voice?
SMS, OTP, WhatsApp Business, and Voice OTP are all supported. RCS Business Messaging is available where the local operator has launched it. All channels run on the same contract and contact model.
Can I be billed in a currency other than USD?
Yes — billing is available in USD / AUD. Volume tiers apply automatically from 100K messages a month.
Does Australia require local-presence numbers?
Not for OTP or transactional alerts — alphanumeric sender IDs work on all major networks. Marketing traffic from local senders typically uses a local-number identity to clear Spam-Act-style scrutiny.
What happens if a route to Australia degrades?
BroadNet runs continuous DLR monitoring on every operator. If a route flaps, traffic is automatically re-shaped to the next-best operator on the same destination, and your account manager is notified with a remediation note within the hour.
Do you sign an SLA for traffic to Australia?
Yes — traffic to this market runs under BroadNet's standard SLA: 99.99% monthly platform uptime, with service credits on enterprise contracts. Support response targets and the credit schedule are published on our Support & SLA page.
