Marketing Agency Lock-in Contracts, Explained

"We gave it a go for 6 months only to find out we are now locked into another 12 month contract." That's a real review from an Australian owner, and it's one of the most common ways people get stuck. Here's the good news almost nobody writing about this will tell you: the regulator is now watching these clauses closely. For 2026-27, the ACCC has named "harmful cancellation terms, including those associated with automatic renewals, early termination fee clauses and non-cancellation clauses" as one of its enforcement priorities. In plain English, the traps in this guide are on the national watchlist.

First, the honest part: not every minimum term is a trap

Let me be fair to my own industry for a second. A minimum term isn't automatically a con. Building a proper system takes real upfront work an agency wears before they've earned much, and some channels, SEO especially, take months to pay off, so a one-month deal can genuinely be too short to do the job. When an agency is honest about why the minimum exists and keeps it reasonable, that's a fair ask.

The problem isn't the existence of a minimum term. It's what gets hidden inside it.

The clauses that turn a contract into a trap

These are all real clause types pulled from published Australian agency terms. Watch for them.

Auto-renewal into a whole new term. The nasty one. You sign for six or twelve months, and buried in the contract is a line that rolls you into another full term unless you cancel in a narrow window you've long forgotten about. One set of terms I read renews "for subsequent periods of the same duration" unless you give notice 30 days before the end. Miss it by a day, and you're locked in all over again.

Full remaining balance on exit. Some contracts say that if you leave early, "the remainder of the agreed contract period will be payable in full." Not the costs they've actually lost, the whole lot. A fair early-termination fee recovers genuine loss and shrinks over time. A full-balance charge regardless of what it really cost them is the kind of penalty term courts have struck down.

The credit-listing threat. Unpaid invoices, including for a term you're trying to leave, "may result in registering this default with a credit reporting agency." This is the written version of the "they sent debt collectors" horror story, and it exists to scare you into staying.

Holding your assets hostage. Clauses that keep your ad accounts, your ad creative, even your website as the agency's property, "at all times and after cancellation." Leave, and you lose the very things you paid to build. There's a whole guide on this one.

Changing the rules whenever they like. "We may change this agreement from time to time," or "may be updated by us without notice." A contract the other side can rewrite mid-stream isn't really a fixed deal at all. This exact kind of term is what the ACCC has taken Amazon to court over, alleging its Prime contracts let it make changes without giving subscribers a way out. Those are allegations the court hasn't ruled on yet.

The one-line test for fair versus trap

Here's the whole thing in a sentence. A fair minimum term is honest about why it exists, fixed in length, rolls to month-to-month afterwards, carries an exit fee based on real loss that shrinks over time, and leaves you owning your accounts. A trap auto-renews into a new full term, charges the full balance no matter what, changes the rules without an exit, and keeps your assets as leverage.

If you're not sure which one you're looking at, that sentence will usually tell you.

What the law actually says

This isn't just my opinion about what's fair. Australian law backs a lot of it.

Since November 2023, unfair terms in standard-form small-business contracts are illegal, not merely unenforceable, for businesses under 100 staff or $10 million turnover. And the courts have form here. In 2022, a Federal Court declared 38 terms across a large company's small-business contracts unfair and void, including automatic renewals and excessive exit fees, plus the right to raise prices whenever they liked, the exact clauses above. Years earlier, the first business-to-business case of its kind struck down eight terms, including auto-renewal and one-sided price rises.

The penalties for getting this wrong doubled to $100 million per breach in March 2026. And the pattern keeps getting punished: this year a subscription company was fined $10 million for a "$2, fully refundable" sign-up that quietly enrolled people into a $45-to-$75-a-month subscription.

I'll be straight with you about the limits of this. I couldn't find a decided case against a marketing agency specifically over a lock-in, and the biggest recent cases are printers and subscription apps, not agencies. But the terms are the same shape, the law applies the same way, and the regulator has said out loud that these are the clauses it's chasing.

How to get out of one you're already in

If you're stuck, here's the honest picture, including one hard truth.

The hard truth first: business-to-business contracts don't come with a cooling-off period. There's no statutory right to simply change your mind. So your real levers are these.

Read your own contract for the actual notice period, and put the deadline in your calendar, because most people get trapped by missing the cancellation window, not by the term itself.

If a term looks unfair, and the ones above are the usual suspects, it may be void under the unfair contract terms law, which means they can't enforce it. That's worth raising in writing, or getting a quick legal opinion on.

And if you're getting nowhere, the Small Business and Family Enterprise Ombudsman offers free dispute assistance, and getting stuck in an agency contract is exactly the sort of thing they help with.

What "no lock-in" looks like when it's actually real

Plenty of agencies say "no lock-in." Fewer show you the exit. The phrase means nothing unless the contract behind it backs it up.

Here's what mine looks like, so you can see the difference. Month to month. No fixed term, and no auto-renewal into anything. Cancel with reasonable notice and no penalty for leaving. And everything, your accounts and everything built on them, is already yours to walk away with. I don't need a lock-in, because if the work is good you'll stay, and if it isn't, no contract should force you to. If an agency has to trap you to keep you, they've already told you what they think of their own work.

If you'd like a second pair of eyes on a contract you're being asked to sign, or one you're trying to escape, bring it to a free teardown. I'll read the clauses with you and tell you honestly which are fair and which are traps. No pitch, and you keep whatever we work out.
