What Should a Law Firm Lead Cost in Australia? Cost per Lead and Cost per Signed Client by Practice Area

You open the monthly report. Cost per lead is $140. Last month it was $95.

Is that bad? Should you be on the phone to your agency, or doubling the budget?

Most principals I speak to can't answer that, and it isn't their fault. The number they've been handed doesn't contain the answer. A lead can cost $20 or $400 and either one can be the better buy. What decides it is what the lead turns into.

This article sets out what Australian law firms are actually paying, using the accounts we manage, and then shows how to read your own numbers against it.

Before you compare anything: is your own tracking right?

Most agencies and law firms we audit are tracking leads incorrectly. The same enquiry gets counted twice, or a view of a page is counted as a lead. Both make an ads account look far better than the phones suggest.

So if you're looking at your account and wondering why your cost per lead is so low and your conversion rate is so high, ask yourself one question. Does it feel like you're getting that volume of enquiries, or is it still quiet? If it's quiet, and nobody on your team is overwhelmed by leads, the tracking is most likely wrong.

The other common cause is free legal advice and legal aid searches. If your campaigns target those terms, clicks and leads get much cheaper, and the numbers look great. Most law firms we speak with do not want those enquiries.

We come back to this in what actually counts as a lead, with examples from real accounts.

What should a law firm lead cost in Australia?

On Google search, a genuine enquiry costs an Australian law firm between about $60 and $560 depending on practice area. The order is what you'd expect: the more a matter is worth, the more firms are prepared to bid for it.

Treat these as reference points, not targets. The family law figure hides a range of $158 to $310 across three firms that bid very differently, which is the subject of the next section.

Why does a cheaper click often mean a more expensive lead?

Because cheap clicks come from vaguer searches and lower ad positions, and fewer of those people become enquiries. We see this inside every practice area.

The Melbourne firm's bids were capped low, so its ads showed for about 15% of relevant searches and mostly in the lower positions. The Queensland firm paid three times as much per click and half as much per enquiry.

The same thing happened in criminal law, where a Sydney firm paying $9 a click paid about $800 per enquiry and a Brisbane firm paying $28 to $35 paid $271. And inside a single commercial litigation account, a loosely matched keyword cost $11 a click and about $1,270 per enquiry, while the exact phrase "commercial litigation lawyers melbourne" cost $74 a click and about $300 per enquiry.

How much does Google Ads cost per click for lawyers in Australia?

Average non-brand clicks run from about $4 for immigration to about $33 for personal injury, and the phrases that signal someone is ready to hire cost two to three times the average.

Location matters as well. Western Sydney personal injury campaigns paid $50 to $65 a click against $28 for Sydney generally, and Gold Coast family law clicks cost about 1.6 times Brisbane inside the same account.

These prices are also climbing. Every account that ran continuously paid more per click in mid-2026 than a year earlier.

Cost per enquiry rose much less than that in the same accounts, because the campaigns were narrowed to fewer, better searches as prices went up. That works, but it has a limit. Most metro firms already appear for only 13% to 38% of the searches they are eligible for, and budget is as big a constraint as ad quality. I've written separately about why personal injury Google Ads costs keep climbing.

Google still earns its place, particularly for family, commercial and estates work, and Google enquiries are often easier to sign because the person is at the end of their search. It just has to be tracked through to signed clients, or you can't tell a good month from an expensive one. Our Google Ads for lawyers page covers how we set that up.

How much do Facebook ads cost per lead for lawyers?

Across nine Australian law firm accounts, Meta enquiries cost $20 to $35 for most personal injury claim types, about $77 for family law, and considerably more for motor accident claims.

Three things in that data are worth knowing.

The claim type sets the price more than the firm does. Inside one Sydney account, motor accident enquiries cost 2.3 times what TPD enquiries cost. The ads cost about the same to show. The difference is that far fewer of the people who click have a claim that fits.

Family law is remarkably consistent. Two unrelated firms landed at $70 and $78, and one of them held that price while doubling its monthly spend.

Meta is not getting dearer. The cost of reaching 1,000 people was flat to slightly lower in 2026 than in 2025, and our longest-running personal injury account has held $20 to $24 per enquiry for 14 months. New accounts do start high, at $80 to $130 in the first month or two, and settle by about month five. That is the campaign learning, not the market moving.

A Meta enquiry is an earlier, colder enquiry than a Google one, so more of them won't qualify. I describe it to principals as panning for gold: not every lead is a fit, and that is priced in. It works when the ad does some of the screening, when the form asks what your intake team would ask anyway, and when someone calls quickly. Our guide to Facebook ads for personal injury firms goes through the structure, and the Facebook ads for lawyers page explains how we run it.

What actually counts as a lead?

This is the question that makes most benchmark comparisons unreliable. Four of the nine Google accounts we reviewed were counting actions that are not enquiries: clicks on an email address, taps on a phone number, even clicks through to LinkedIn. Count only calls and completed forms, and the cost per enquiry rises.

The same applies on Meta. An enquiry through a form that opens inside Facebook costs less than one that sends the person to your website, and they are not the same product.

Whenever you add friction, the cost per lead goes up and the quality usually goes up with it. One Sydney motor accident firm pays more than $250 an enquiry because its form screens hard. At one point we were preparing to "fix" that, until the firm's feedback showed what those enquiries became: matters with estimated fees of $60,000 and above.

Cost per lead vs cost per signed client: which number matters?

Cost per signed client, because it includes everything cost per lead leaves out: lead quality, how fast your team calls and how well they sign.

Here is one NSW workers compensation and TPD firm's Meta campaign over 12 months, reduced to 100 enquiries.

Two stages do the damage. Nearly half of enquiries were never reached, and most of the people who were reached did not have a claim the firm would run. But of the matters the firm wanted, it signed almost two in three. That pattern is common in law: once a genuinely qualified person is speaking to a lawyer, they usually sign.

Across the firms with complete tracking, the picture looks like this.

Compare the two NSW firms. They advertise in the same state, but for different claim types. The motor accident firm pays almost five times more per lead than the workers compensation and TPD firm, and more than seven times as much per client. It also makes a much higher return, because its average matter is worth far more. The Victorian firm has the cheapest leads in the table and the lowest sign rate, and still performed well.

Where a return is marked "estimated", the fees are the firm's own estimates recorded at sign-up. Most injury matters take 18 months to three years to resolve, so waiting for the fee before judging the campaign would mean years without feedback.

What is a good cost per signed client for a law firm?

One your average fee can comfortably carry. As a working rule, most firms are comfortable paying 10% to 20% of the first fee to acquire the matter.

That gives very different ceilings by practice area. A motor accident firm signing matters worth $60,000 and above can pay $3,500 to $4,000 per client and do well. A family law firm on a $6,000 to $12,000 average fee needs to be near $2,000, which is where the two in the table sit, and at 3x to 5x those campaigns work but need a close eye. Criminal law is the tightest. With a $3,000 average matter you realistically need to be under $500 per signed client, and the Google prices above make that hard. If your criminal matters are $10,000 to $15,000, paying $1,000 to $1,500 per client is a good position.

Once you know your ceiling, the budget conversation changes. If a signed client costs $3,500 and you want ten more of them, that is $35,000. It becomes arithmetic instead of a feeling.

How many leads does a law firm need to sign one client?

Between 10 and 50 in the firms we track, and how hard the form screens decides which end you land at. The heavily screened motor accident firm signs about 1 in 17. The lightly screened Victorian TAC firm signs about 1 in 52. Both are healthy campaigns.

The stage to watch is the middle one. Across personal injury campaigns, 10% to 40% of leads turn out to be matters the firm would take. If that share is low, the targeting or the form needs work. If it is healthy but few of them sign, the problem is intake. Those need completely different fixes, which is why a single "conversion rate" is not much use.

Why are my law firm leads so expensive, or so bad?

Usually for one of four reasons, in our experience auditing accounts.

1. Brand searches, Performance Max and search are blended, so nobody can see what a new enquiry really costs.
2. Soft actions are counted as leads, as in the examples above.
3. The offer is broad. "Free consultation, all family law matters" attracts everyone, including the people you can't help.
4. The firm never reports back which leads were real, so the campaign can only be steered towards the cheapest lead.

The fourth matters most. An ad platform learns from whatever signal it is given. If the only signal is "a form was submitted", it finds more people who submit forms. If it is told which of those became clients, it finds more of those. Without that feedback, a campaign producing $80,000 matters at $250 a lead looks worse than one producing nothing at $15 a lead, and it will get "optimised" in the wrong direction.

How do you reduce cost per signed client without hurting quality?

Fix the stage that is leaking, and for most firms that is response time, not the ads. In the funnel above, 47 of every 100 enquiries were never reached.

Enquiries arrive when people are at work, not when it suits the firm. Across the call-led firms, around half of all enquiries landed between 9am and 1pm, and Monday to Thursday were almost identical.

Two exceptions are useful. Criminal law kept converting in the evenings and at weekends, which fits the nature of the work. Commercial litigation produced no enquiries at all from $2,500 of weekend clicks, and it was the only practice area where desktop out-converted mobile. Everywhere else, mobile was about 77% of spend and converted slightly better.

The best-performing firm we work with aims to phone within five minutes of a form arriving, and sends the costs agreement within four hours if the matter qualifies. When Clio mystery-shopped 500 US law firms for its 2024 Legal Trends Report, only 40% answered the phone. We see much the same here, and it's why we wrote about the 60-second rule for personal injury leads.

After speed, the levers in rough order of impact are: form questions that match what intake asks, SMS verification so the number is real, ads that speak to one type of client, and then budget moved towards whatever produced signed clients. The full sequence is in our growth system.

How much do lawyers pay per lead from lead generation companies?

I'm not going to quote vendor price lists, because the ones published online are almost all American and the Australian market is small and opaque. What our clients tell us after trying it is consistent: the leads were sold to several firms at once, they were hard to reach, and nobody could say what a signed client had cost.

There is also a compliance question. Queensland and New South Wales have both legislated against claim farming in personal injury, and the conduct rules on referral fees apply everywhere. This is general information, not legal advice, so check the current position with your law society before paying anyone per lead. We covered the practical side in Can lawyers buy leads? and why personal injury firms should stop buying leads from vendors.

How much should a law firm spend on marketing?

Work it out from the bottom up. Take the number of matters you want each month, multiply by your tracked cost per signed client, and add about 20% for testing. Then check it against cash flow.

You'll see percentages of revenue quoted online, usually from American surveys. I couldn't find a credible Australian figure, and I don't think it's the right question. A percentage tells you what other firms spend. It doesn't tell you whether your next dollar comes back.

Two practical limits. Below about $3,000 a month in ad spend per campaign there isn't enough data to test more than two or three audiences. And personal injury firms need to plan for the cash lag, because the fee from a matter signed today may be two years away.

What is a good return on ad spend, and how long until it pays back?

In the firms we track, Google-led family law campaigns return about 3x to 5x on ad spend and personal injury campaigns 8x to 25x, measured on fees or estimated fees against ad spend only. The highest figures come from firms with high-value matters, fast intake and consistent feedback. They are not typical of every firm, and I'd be wary of anyone who promises them.

On timing, image ads are usually live within two weeks and video by week three or four. Some accounts start quickly. One Adelaide firm signed four clients in its first half month. Others take three or four months of testing, and as the Meta data above shows, the first couple of months are usually the most expensive. I tell new clients to think in three to six months.

For personal injury, "pays back" has two meanings. The estimated return shows up in weeks. The cash shows up when matters settle. It helps to aim for a mix that includes some matters likely to resolve in months, so the campaign helps fund itself.

The question is what a client costs, not what a lead costs

Cost per lead is the easiest number in marketing to report and the least useful one to run a law firm by. The firms in this article paid $18 a lead and $254 a lead and both did well. Another firm could pay $50 a lead, sign nobody and never find out why.

So ask for two numbers: what a signed client costs you, and what that client is worth. If you'd like help finding yours, that is the work we do for personal injury firms, family law firms and law firms generally.
