Marketing Your Business Online: A Legal Guide

Online marketing can supercharge your growth. From social media and email to search ads and influencer collaborations, you have more ways than ever to reach customers across Australia.

But with that opportunity comes legal responsibility. Australian laws set clear rules for how you advertise, collect data, manage reviews and run promotions online.

This guide walks you through the key legal issues, the policies and contracts you’ll likely need, and practical steps to market confidently and compliantly - so you can focus on growing your brand.

Why Online Marketing Needs A Legal Strategy In Australia

Good marketing builds trust. The law protects that trust by setting baseline standards for truthful advertising, fair treatment of consumers, and responsible use of personal information.

If your campaigns stray outside those rules - even unintentionally - you could face complaints, fines or reputational damage. The risk often rises as you scale: bigger audience, more campaigns, more data.

With a simple legal framework in place (policies, clear processes and the right contracts), you can move faster, reduce risk and keep your brand credible in the long run.

What Laws Apply To Digital Marketing?

Several Australian laws apply to how you promote and sell online. Here are the main ones most small businesses should know.

Australian Consumer Law (ACL): Truthful Advertising

The ACL prohibits conduct that is misleading or deceptive. In short, your advertising must be accurate, substantiated and not likely to mislead the average consumer. This general rule sits in Section 18 of the ACL.

Specific false representations (for example about price, quality, testimonials, or sponsorships) are also banned. Your pricing and promotional claims should be clear, prominent and backed by evidence.

Tip: Review ad copy, landing pages and social posts together - a claim that’s “technically true” in one place can still mislead when viewed in context across your funnel.

Advertised Pricing And “From”/“Was” Pricing

If you display prices in ads or on your site, make sure the total price is transparent and any conditions are obvious (e.g. minimum term, add-on fees). “Was/Now” and “from $X” price claims must reflect genuine savings and representative offers. See a practical overview of advertised price laws.

Spam Act 2003: Email And SMS Marketing

Commercial electronic messages require consent, accurate sender identification and a functional unsubscribe in every message. Keep a clear record of opt-ins and honor unsubscribes promptly.

If you’re building a mailing list, make sure your sign-up forms state the purpose and link to your Privacy Policy. Read more on Australia’s rules in our guide to email marketing laws.

Privacy Act 1988: Data Collection And Use

If you collect personal information (names, emails, phone numbers, purchase history, IP addresses or device identifiers linked to a person), you must handle it transparently and securely. Most online marketing involves collecting at least some personal information.

In practice, that means publishing a clear Privacy Policy, only collecting what you need, using it for the purpose you stated, and keeping it safe. If you use analytics, pixels or cookies, also consider a dedicated Cookie Policy and cookie consent practices.

Telemarketing And Cold Outreach

If your marketing includes phone outreach, ensure you comply with Do Not Call rules and time-of-day restrictions. Align scripts with your consumer law obligations (no misleading statements and clear opt-out pathways). If you text prospects, the Spam Act rules will also apply (consent and easy unsubscribe).

Competitions, Giveaways And Promotions

Competitions and giveaways can be powerful, but they’re regulated. Depending on your structure, location and game type (chance vs skill), you may need permits and must follow advertising rules and your own terms. Get across Australia’s giveaway laws before you launch that campaign.

What Policies And Contracts Should Your Website Have?

Your website or app is usually the hub of your marketing. It should clearly set the rules for visitors and customers, explain how you handle data and avoid surprises at checkout.

Privacy Policy

A Privacy Policy tells users what personal information you collect, how you use and share it, and how they can contact you or make a complaint. It’s essential for most online marketing activities - especially if you run email lists, analytics, remarketing pixels, payment pages or contact forms. You can implement a tailored Privacy Policy across your site and any hosted landing pages.

Cookie Policy

If you use cookies or similar technologies for analytics, remarketing or personalisation, publish a Cookie Policy that explains what you use and why. Combined with a consent banner, this helps you be transparent about tracking and satisfy user expectations.

Website Terms And Conditions

Website Terms set out how people may use your site (and what they can’t do), IP ownership, acceptable use rules, disclaimers and liability limits. If you sell online, your Terms should also cover ordering, pricing, refunds, shipping, and returns under the ACL. See our Website Terms and Conditions for what’s typically included.

Ecommerce Or Platform-Specific Terms

If you run an online shop or marketplace, you’ll also need terms of sale and payment; if you operate a subscription, include renewal, cancellation and refund rules. Make sure your checkout flows surface key terms clearly and don’t bury important limitations or fees.

Can You Run Giveaways, Influencer Campaigns And Collect Reviews?

Yes - these are common parts of online marketing. You just need to set them up properly and keep consumer law top of mind.

Giveaways And Competitions

Before launching, lock in clear, accessible competition terms that cover eligibility, how to enter, judging rules or draw mechanics, prize details and how winners are notified.

Check whether your promotion is a game of chance or skill and if any state or territory permits apply. Align your advertising with your promotion terms (no fine-print surprises), and keep evidence of the draw or judging process.

Planning a national campaign? Review the relevant rules for each state, and confirm you meet Australia’s core giveaway laws before you go live.

Influencer And Affiliate Marketing

Influencer posts must be truthful, clearly disclosed as ads or sponsored where relevant, and consistent with your own claims. If the content mentions a price, discount or feature, you’re responsible for ensuring it’s accurate and compliant.

Use a written agreement that covers deliverables, disclosure requirements, approval rights, brand guidelines, IP ownership and termination. Provide clear instructions to creators on disclosure (for example, using “Ad” or “Sponsored” upfront) and claims they may or may not make.

Reviews And Testimonials

Genuine reviews are powerful. Don’t post or commission fake reviews, don’t suppress negative feedback, and don’t edit out material information that would change a reader’s impression. If you incentivise reviews, make that fact clear and ensure the reviews remain honest and balanced.

Have a process for responding to complaints quickly and fairly. If you need to challenge a false or defamatory review, follow a measured approach and keep records of your communications.

Ad Copy And Landing Pages

Across both ads and landing pages, keep claims clear and supportable. Avoid “bait” tactics like advertising a headline deal with very limited availability unless you clearly disclose the limits and can meet the expected demand.

Be especially careful with pricing claims, introductory offers, subscriptions and auto-renewals. Ensure the key terms are prominent before the customer takes action - not hidden behind a link. For more on price representations, see the overview of advertised price laws.

A Step-By-Step Legal Checklist For Online Marketing

Here’s a practical sequence to set up your marketing legally and efficiently.

1. Map Your Channels And Data Flows. List your marketing tools (email platform, CRM, analytics, ad pixels), what data they collect and where it goes. This helps you write accurate disclosures and identify risks early.

2. Publish Core Website Policies. Add a tailored Privacy Policy, a Cookie Policy if you track users, and clear Website Terms and Conditions.

3. Set Consent And Unsubscribe Standards. Use opt-in for email/SMS, include an unsubscribe in every message, and maintain suppression lists. Keep records of consent and preference changes. Align with Australia’s email marketing laws.

4. Build An Ad Review Checklist. Before launching, confirm your claims are accurate, pricing is clear, qualifications are prominent, and you can substantiate performance or comparison claims. Cross-check against the ACL’s general prohibition on misleading conduct in Section 18.

5. Prepare Promotion And Partnership Terms. Create template terms for competitions (eligibility, entry, draws, prizes) and influencer arrangements (deliverables, disclosure, approvals, IP and termination). Keep templates ready so you can move quickly but consistently.

6. Design Transparent Checkout And Pricing. Show total prices early, disclose subscription renewals and minimum terms clearly, and avoid add-on surprises. Make refunds and consumer guarantees easy to find and consistent with your site terms.

7. Train Your Team. Educate staff and contractors on acceptable ad claims, disclosure rules, how to handle customer data, and when to escalate legal questions. Create a quick-reference guide so everyone stays aligned.

8. Monitor, Document And Improve. Keep evidence of claims and campaign decisions, monitor complaints and unsubscribe rates, and audit your privacy and consent settings periodically (especially when you add new tools).

Common Risk Areas (And How To Tackle Them)

As you scale your marketing, these are the trouble spots we see most often - and quick ways to reduce risk.

• “Was/Now” Discounts That Aren’t Genuine. Ensure reference prices are real and recent, and that enough stock was sold at the “was” price to make the comparison fair. If in doubt, rethink the claim.

• Hidden Fees Or Conditions. Put key terms and costs where customers will see them before they act (not just in the footer). Use plain language and avoid ambiguity.

• Over‑Zealous Email Campaigns. For list growth, rely on clear opt-ins, double opt-in if helpful, and immediate honoring of unsubscribes. Don’t purchase email lists.

• Unclear Influencer Disclosures. Ask creators to disclose upfront and in a way that’s obvious on every platform (caption and in-video where relevant). Provide them examples of acceptable phrasing.

• Loose Promotions. Avoid running giveaways without written terms. Keep draw records, announce winners as promised, and meet any permit obligations.

• Data Creep. As you install new tools, revisit your Privacy Policy and Cookie Policy to ensure they still reflect reality. Update consent banners if your tracking changes.

Key Takeaways

• Online marketing is powerful, but it sits under Australian Consumer Law - keep claims accurate, pricing transparent, and disclosures clear.
• Email and SMS campaigns require consent, sender identification and easy unsubscribes under Australia’s email marketing laws.
• Publish core website documents: a Privacy Policy, a Cookie Policy (if you track users), and Website Terms and Conditions that set clear expectations.
• Competitions and influencer campaigns are fine when properly documented, clearly disclosed and aligned with giveaway rules and consumer law.
• Build simple internal processes - ad claim checks, consent records, template terms - so your team can move fast without cutting corners.
• Review and update your policies and practices as tools change, and get legal advice early if you’re unsure about a claim or campaign structure.
