SMS Compliance in Australia
A practical overview of the rules that affect SMS messaging and marketing in Australia, with a checklist before you launch.
Key Rules for SMS in Australia
Commercial SMS in Australia must comply with the Spam Act 2003: consent, clear sender identification and a functional unsubscribe option. The ACMA enforces these rules and also oversees measures against SMS sender ID impersonation.
Australia's Spam Act 2003 and New Zealand's Unsolicited Electronic Messages Act 2007 require consent, clear sender identification and a functional unsubscribe option in commercial messages.
Data Protection
Australian businesses covered by the Privacy Act 1988 must follow the Australian Privacy Principles, including a clear privacy policy on the website.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Collect and record consent (or confirm an existing customer relationship) before sending, with the date and source.
- Use a registered sender ID or number that recipients can recognise as your business.
- Identify your business in every message and keep promotional and service messages separate.
- Give a simple way to opt out of marketing and process opt-outs quickly across all your systems.
- Send in the recipient's local daytime hours and keep frequency reasonable.
Contact data
Format numbers in international E.164 format with the +61 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Australia spans several time zones; the main business zone we plan around is the Australia/Sydney time zone (UTC+10:00 in October 2026). Schedule SMS campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Sydney, customers commonly use English, with Mandarin, Arabic, Hindi and other community languages. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Australia
Australia has very high smartphone use; SMS is still the most trusted channel for appointment reminders, delivery notices and two-factor codes, while Messenger and WhatsApp are popular for personal chat. Branded alphanumeric sender IDs are common, and since 1 July 2026 they must be listed on the ACMA's national SMS Sender ID Register: texts from unregistered sender IDs are relabelled 'Unverified', so businesses register through their SMS provider before sending.
Contactless card payments and Apple Pay or Google Pay are the norm, Afterpay began in Australia and remains popular, and PayID makes instant bank transfers easy. Prices must be shown including GST. The retail year peaks at Click Frenzy, Black Friday, Christmas and the Boxing Day sales, and the end of the financial year on 30 June drives EOFY promotions.
Australia's economy is driven by mining (iron ore, coal, gas and gold), agriculture, education for international students, tourism and services. GST is 10%. The Spam Act 2003 requires consent, sender identification and a working unsubscribe option for commercial SMS and email, enforced by ACMA, and the Do Not Call Register blocks telemarketing calls. Buy now, pay later services such as Afterpay are popular, and contactless card payments are used for most purchases.
Advertising Alongside Messaging
Advertising must comply with Australian Consumer Law and the AANA Code of Ethics, including clear distinction of advertising content.
