Advertising is one of the fastest ways to grow a small business - but it’s also one of the quickest ways to create legal risk if you’re not careful.
In Australia, your ads aren’t just “marketing”. They’re often treated as statements you’re making to customers (and sometimes promises), which means consumer law, privacy rules, spam rules and industry-specific regulations can all apply.
The good news is that you can still advertise confidently. You just need a practical system for checking your claims, prices, offers and marketing channels before anything goes live.
Below, we’ll walk you through the key legal risks when you advertise in Australia, the compliance areas that commonly trip up small businesses, and practical tips you can use immediately - whether you advertise online, on social media, via email, with influencers, or in-store.
What Laws Apply When You Advertise In Australia?
When you advertise, the main legal framework you need to keep in mind is the Australian Consumer Law (ACL). The ACL applies to most businesses that supply goods or services to consumers (and in many cases, to other businesses too).
Beyond the ACL, other laws can apply depending on how you advertise and what you’re promoting. In practice, most small businesses should assume these areas matter:
- Australian Consumer Law (ACL): regulates misleading or deceptive conduct, advertising claims, pricing displays, and consumer guarantees.
- Spam and direct marketing rules: relevant if you advertise through email, SMS, or similar messaging channels (including the Spam Act 2003 and related rules).
- Privacy rules: relevant if your advertising involves collecting customer data (sign-up forms, lead magnets, cookies, pixel tracking, retargeting, etc.).
- Trade promotions and competitions rules: relevant if your advertising includes giveaways, contests, raffles or “win” promotions (requirements can differ by State/Territory and the promotion type).
- Intellectual property (IP): relevant if your advertising uses creative assets, music, photos, slogans, logos, or comparisons with competitors.
It sounds like a lot - but most compliance comes down to a few recurring themes: don’t mislead people, be transparent about price and terms, and get permission where required.
How Do I Avoid Misleading Or Deceptive Advertising?
If you’re going to advertise, this is the area to get right first.
Under the ACL, you generally must not engage in misleading or deceptive conduct (or conduct that is likely to mislead or deceive). That rule applies across your entire customer journey - your website, social posts, paid ads, emails, brochures, sales calls and even what your staff say in-store.
A useful way to think about it is this: if a reasonable customer could come away with the wrong impression from your ad, you may have a problem - even if you didn’t intend to mislead.
Common Advertising “Red Flags” For Small Businesses
Here are examples of advertising issues that commonly lead to disputes or complaints:
- Overstated results: “Guaranteed results” or “It will fix your problem in 7 days” when results vary.
- Unclear conditions: advertising a deal without clearly stating key limits (dates, exclusions, minimum spend, limited stock).
- Before-and-after style claims: especially for health, beauty, fitness, finance, and education services (where outcomes vary widely).
- “Free” offers that aren’t really free: where the customer must pay shipping, sign up to a subscription, or meet hidden conditions.
- False urgency: countdown timers or “limited time only” messages that reset or run continuously.
- Misleading comparisons: “Cheaper than everyone else” without a reasonable basis for that comparison.
Even if your overall business is honest, advertising often gets risky when marketing language gets vague or absolute.
If you want a deeper understanding of how the ACL analyses this issue, it helps to understand the misleading or deceptive conduct factors that courts and regulators look at.
Practical Tip: Use A “Claim Checklist” Before You Publish
Before you advertise, pressure-test each claim with these questions:
- Can we prove it? Do you have records, testing, data, or evidence to back the claim up?
- Is it always true? If not, your wording should reflect that (for example, “may help” vs “will”).
- What does the customer think it means? Advertising is judged by impressions, not just technical accuracy.
- Are key conditions clear? Put the important terms close to the headline claim, not buried.
One of the simplest ways to reduce risk is to make your advertising more specific and more transparent. It can actually improve conversion as well, because customers know what they’re getting.
Pricing is one of the most common areas where small businesses accidentally breach advertising rules - especially when you run sales, bundles, “from” pricing, deposits, or time-limited promotions.
If you advertise a price, make sure the price is:
- Accurate (no hidden add-ons that should have been disclosed upfront);
- Clearly presented (easy to understand); and
- Consistent across channels (your website, social media ads, and checkout flow shouldn’t contradict each other).
Advertised Prices And Hidden Extras
Be cautious about extra fees that only appear late in the checkout process. Depending on your industry, this can include:
- Booking or service fees
- Mandatory setup charges
- Compulsory delivery fees
- Automatic add-ons
In many situations, the safest approach is to show the total minimum price a customer will pay, and then explain any variable costs clearly.
Pricing transparency is a big compliance topic in Australia, and it’s worth understanding the advertised price laws expectations before you launch a major campaign.
“Was/Now” Discounts And Sales Claims
If you advertise a discount (for example “was $199, now $99”), you should be confident you have a reasonable basis for the “was” price. If the product was never (or rarely) sold at that higher price, the “discount” can be misleading.
As a practical habit, keep internal records of:
- the date range the higher price applied;
- sales history at that price; and
- when the discount started and ended.
This kind of recordkeeping is also useful if a customer complains or if a platform asks you to substantiate claims.
Giveaways are a great way to advertise - but they can become regulated quickly depending on the structure.
If your advertising includes a chance to win a prize (even something small), you may trigger trade promotion rules. These rules differ depending on the State or Territory where the promotion is run, and on factors like whether entry is free, the prize value, and how winners are drawn.
In some cases, you may need a permit (or specific disclosures), while in others you may not - but you’ll still generally need clear written terms and a fair process.
At a minimum, you should clearly set out the terms, including eligibility, entry method, selection process, and when/how the winner is notified.
If giveaways are part of your marketing plan, it’s worth being across the giveaway laws so you don’t accidentally run a promotion that needs permits or specific disclosures.
Digital Marketing Rules: Email, SMS, DMs And Online Advertising
Online advertising can feel “informal” because it’s fast and creative - but the legal expectations are largely the same as traditional advertising. If anything, the risk is higher because ads can be shared widely and screenshots last forever.
Email Marketing And Customer Lists
If you advertise via email, you need to think about:
- Consent: do you have permission to send marketing emails?
- Identification: does the message clearly identify your business?
- Unsubscribe: is there a functional unsubscribe option?
Many businesses accidentally create risk by buying lists, scraping emails, or assuming that “someone gave us their business card once” equals ongoing marketing consent.
It’s a good idea to build your email practices around the email marketing laws requirements so your advertising channel doesn’t turn into a compliance headache.
Telemarketing, SMS And Direct Outreach
If you advertise via phone calls or SMS (or you use a third party to do it), there can be additional rules around how and when you contact people, and what must be disclosed during the call.
These campaigns can also create brand risk - even if they’re legal - because customers tend to complain more about unexpected contact.
If direct outreach is part of your strategy, you’ll want your team (and any contractors) trained on the telemarketing laws basics.
Online Reviews, Testimonials And “Social Proof”
Testimonials are powerful, but you need to use them carefully. A few practical rules of thumb:
- Don’t edit testimonials in a way that changes meaning.
- Don’t present a one-off experience as “typical” if it isn’t.
- Be careful with incentives. If you give discounts or gifts for reviews, ensure it’s not misleading and the overall impression remains fair.
If you use case studies or “results” stories, make it clear what factors contributed to those results, and whether outcomes vary.
Using Images, Videos And Influencers: Permissions And IP Traps
Advertising is increasingly visual - reels, short-form videos, brand photography, user-generated content, and influencer partnerships.
That’s great for marketing, but it can create legal exposure if you don’t have the right permissions.
Photos And Videos Of Customers (And The Public)
If you feature customers, attendees at an event, or people in your store in your advertising, you should think about consent.
In particular, if you’re using identifiable images for promotional purposes, a written release can help avoid disputes later (for example, if someone is unhappy about being featured or wants the content removed after it has been boosted as an ad).
Depending on the context, you may want to build your content process around photography consent laws principles, and have a consistent way to capture and store permissions.
A common mistake is assuming:
- stock images are always free to use,
- a social media audio track is automatically licensed for business ads, or
- you can repost someone else’s photo because they tagged you.
In reality, content is usually protected by copyright, and a platform’s “available audio” doesn’t necessarily mean you can use it in paid advertising or commercial promotions.
If you work with creators, agencies or freelancers, you’ll also want to confirm who owns the finished content and whether your business has the right to use it across all advertising channels.
Influencer Advertising And Disclosure
If you use influencers or ambassadors to advertise your products or services, you need to consider:
- Disclosure: the audience should be able to tell when content is advertising (for example, with clear “ad” or “paid partnership” labels).
- Accuracy: influencers shouldn’t make claims you can’t back up (and your business can still be responsible for the overall impression).
- Usage rights: whether you can repost their content and/or use it in paid ads.
The safest approach is to have a written influencer agreement that covers what can be said, what can’t be said, the approval process, and the licensing of content.
What Legal Documents Help Protect Your Advertising And Marketing?
Good advertising isn’t only about compliance - it’s also about managing commercial risk.
Having the right legal documents in place can reduce confusion, prevent disputes, and help your marketing run consistently (especially as you scale or outsource parts of your marketing).
Depending on your business, these documents may be useful:
- Website Terms & Conditions: sets rules for using your site, and can support your marketing claims by clearly stating what you do (and don’t) provide.
- Customer Terms: if you advertise services, inclusions, delivery timeframes or refund rules, your customer contract should match the message in your ads.
- Privacy Policy: if your advertising collects personal information (newsletter forms, lead gen, remarketing), a Privacy Policy is usually essential.
- Competition Terms: if you run giveaways, clear written terms help show exactly how the promotion works and protect you if someone complains about the process.
- Employment or Contractor Agreements: if staff manage your social media or customer comms, an Employment Contract (and supporting policies) can help set expectations about posting, brand voice, confidentiality and approvals.
- Content releases and licences: if you use customer images or professional photos, written releases/licences can prevent later disputes about usage.
One practical tip: align your advertising workflow with your contracts. For example, if your ads promise “same-day dispatch”, your operations need to support that - and your customer terms should define what “dispatch” means (and what happens during peak periods).
