How Much Does a Commercial Lawyer Cost in Australia?

A commercial lawyer in Australia typically charges somewhere between $200 and $880 an hour, with most matters falling between $350 and $650 depending on the lawyer’s seniority and the firm’s location. For defined, routine work — reviewing a contract, checking a lease, setting up a company — many firms now quote a fixed fee instead, commonly ranging from around $600 to $8,000 depending on what the matter actually involves. The honest answer is that the final number depends far more on what you’re asking a lawyer to do than on which firm you call.

This guide breaks down where those figures come from, what pushes a bill up or down, and how to get a number you can budget against before any work starts.

Commercial Lawyer Fees: Hourly Rates by Experience

Commercial law sits toward the middle-to-upper end of the general range, because it tends to involve contracts, corporate structuring and commercial risk that carry real consequences if drafted poorly. Based on current rates reported across multiple commercial law firms and legal-cost guides, here’s roughly what to expect by seniority:

These are industry-reported ranges, not a fixed price list — individual firms set their own rates, and the actual figure a client pays depends on who is doing the work and how much senior oversight the matter needs. Most firms bill in six-minute units, so a 20-minute phone call is charged as a fraction of an hour, not rounded up to a full one.

Fixed Fee vs Hourly Billing for Commercial Work

Hourly billing charges for the actual time spent, which makes sense for work that’s genuinely unpredictable — a dispute that might settle in a week or drag on for a year. The downside is that the client carries the risk if a matter turns out to be more complicated than expected.

Fixed-fee billing sets the price before work starts, based on a defined scope. It works well for commercial matters with a clear, bounded deliverable — a contract, a lease, a company registration — where the lawyer can reasonably estimate the work involved in advance.

For most of the matters a growing business actually needs — contracts, leases, terms and conditions, company formation — a fixed fee removes the single biggest source of anxiety clients report: not knowing what the final bill will look like.

What Affects a Commercial Lawyer’s Fees?

The following factors explain most of the difference between a quick, inexpensive matter and an expensive one:

• Complexity. A simple supplier agreement takes far less time than a multi-party shareholders’ agreement with bespoke exit and dispute clauses.
• Urgency. Work that needs to be turned around in 24–48 hours often costs more than the same task on a standard timeline, because it requires a lawyer to reprioritise other client work.
• Document volume and number of parties. More documents and more parties to negotiate with both add time.
• Seniority required. Higher-risk or higher-value matters are usually overseen by a more senior (and more expensive) lawyer, even if a junior does some of the drafting.
• Location. Firms in capital-city CBDs typically carry higher overheads than regional or suburban practices, which flows through to hourly rates.
• Whether a barrister is needed. Litigation that reaches court may require a barrister’s fees on top of the solicitor’s, which are billed separately.

Typical Costs for Common Commercial Legal Services

Where a matter has a clear scope, most commercial firms will quote a fixed fee rather than bill hourly. Industry-reported ranges for common services look roughly like this:

These figures vary by firm and by exactly what’s included — always confirm whether a quote covers one round of revisions, negotiation with the other side, and any required registrations, or whether those are billed separately.

Your Right to Know the Cost Upfront

This isn’t just good practice — it’s a legal requirement. Under the Legal Profession Uniform Law, a lawyer must give a client written costs disclosure once legal costs are likely to exceed $750 (before disbursements or GST). That disclosure has to include a reasonable estimate of total costs, the basis on which those costs will be calculated, and the client’s right to negotiate the costs agreement, negotiate the billing method, request a lump-sum bill, request an itemised bill, and seek help from the relevant regulator if a dispute arises.

In practice, this means any commercial lawyer quoting on a matter of meaningful size is obliged to put the basis of their fees in writing before significant work begins — a client should never be left guessing.

How to Get an Accurate, Fixed-Fee Quote

The most reliable way to get a number you can actually plan around is to give the lawyer a clear, specific scope: what document or matter needs attention, how urgent it is, and how many parties are involved. A vague request (“I need help with a contract”) is far harder to price accurately than a specific one (“I need a two-party supply agreement reviewed and negotiated within a week”).

At I Global Lawyers, commercial matters are quoted on a transparent, fixed-fee basis wherever the scope allows it, so clients know the cost before committing. The firm’s commercial lawyer team also handles urgent matters, and with more than 15 languages spoken across the practice, non-English-speaking business owners can get advice without a communication barrier adding further cost or delay. For a specific matter, the most useful next step is a short outline of what’s needed, which the team can turn into a fixed-fee quote rather than an open-ended hourly estimate.

Need a Clear Cost Estimate for Your Commercial Matter?

The ranges in this guide are a starting point — your actual cost depends on what you’re trying to do, not a generic hourly figure. I-Global Lawyers’ corporate and commercial law team can tell you upfront whether your matter suits a fixed fee or needs hourly billing, and under the Legal Profession Uniform Law, you’re entitled to that costs disclosure before substantial work begins — not after.

FAQ for Commercial Lawyer’s Cost

Do commercial lawyers charge GST on their fees? 

Yes. Legal fees in Australia are subject to GST, which is added on top of the quoted professional fee and should be shown separately on any costs agreement or invoice.

What’s the difference between a commercial lawyer and a general solicitor? 

A commercial lawyer focuses specifically on business-related matters — contracts, corporate structuring, leases, commercial disputes — while a general solicitor may handle a broader mix of personal and business matters. For anything involving business risk, a lawyer with specific commercial experience is usually better placed to spot issues a generalist might miss.

Can legal fees be negotiated? 

Often, yes. Clients can ask about fixed-fee options, request a cost cap, or negotiate the billing method before work begins — this is an explicit client right under the Legal Profession Uniform Law’s costs disclosure rules.

What happens if a matter costs more than the original estimate? 

For hourly-billed matters, costs can run over an initial estimate if the scope changes or the matter proves more complex than expected; a lawyer should flag this and, where required, provide updated disclosure. For a genuine fixed-fee quote, the price shouldn’t change unless the agreed scope changes.

Are disbursements included in a fixed fee? 

Not always. Disbursements — third-party costs like search fees, filing fees or registration costs — are often billed separately from the professional fee, even under a fixed-fee arrangement. It’s worth confirming this explicitly before work starts.
