Ashurst Perkins Coie

Below is a practical shortlist for Australia—not just “prestige” names, but firms that corporates, PE funds, banks, government clients and mid-market businesses actually brief.

Quick answer: the best “default” shortlist

If you want the safest top-tier commercial-law shortlist in Australia, start with:

1. Allens
2. Gilbert + Tobin
3. Herbert Smith Freehills Kramer
4. Mallesons — formerly the Australian/Singapore arm of King & Wood Mallesons
5. Ashurst Perkins Coie
6. Clayton Utz
7. Corrs Chambers Westgarth
8. MinterEllison

That aligns closely with current legal-directory rankings: Chambers 2026 has Allens, Gilbert + Tobin, HSF Kramer and Mallesons in Band 1 for Corporate/M&A in Australia, with Ashurst Perkins Coie, Clayton Utz and Corrs in Band 2; Legal 500 2026 puts Ashurst Perkins Coie, Allens, Gilbert + Tobin, HSF Kramer and Mallesons in Tier 1, followed by Corrs, MinterEllison and Clayton Utz in Tier 2.

Best picks by need

My practical recommendations

Best overall premium commercial firms

1. Allens
Best all-round premium choice for major corporates, financial institutions, infrastructure, energy, M&A, disputes and regulatory work. If you want a safe blue-chip Australian firm, Allens is one of the first calls.

2. Gilbert + Tobin
Excellent for transactions, competition, tech, private equity, corporate advisory and strategic matters. Often seen as a sharper, deal-focused alternative to the traditional full-service giants.

3. Herbert Smith Freehills Kramer
Very strong for M&A, disputes, energy/resources, infrastructure and cross-border work. The firm became Herbert Smith Freehills Kramer after HSF combined with Kramer Levin in 2025. (hsfkramer.com)

4. Mallesons
Still one of the core Australian commercial-law brands, especially for banking, finance, major corporate work, funds, capital markets and regulatory matters. Note the naming change: the Australian/Singapore business now uses Mallesons following the formal separation of the Chinese and Australian partnerships on 30 March 2026. (landing.kwm.com)

5. Ashurst Perkins Coie
Strong for finance, infrastructure, resources, energy, public M&A and international transactional work. Ashurst and Perkins Coie partners approved their combination in 2026 to form Ashurst Perkins Coie. (ashurstperkinscoie.com)

Best full-service “big Australian business” firms

6. Clayton Utz
A very strong choice for commercial law, litigation, government, infrastructure, regulatory and real estate. Best Law Firms Australia named Clayton Utz “Law Firm of the Year” for Commercial Law in its 2027 edition. (bestlawfirms.com)

7. Corrs Chambers Westgarth
Premium independent Australian firm, good for corporate, competition, disputes, IP/tech, infrastructure and strategic advisory work. Best Law Firms Australia named Corrs for both Information Technology Law and Intellectual Property Law in its 2027 awards. (bestlawfirms.com)

Best Law Firms Australia named MinterEllison for Construction/Infrastructure Law and Real Property Law in its 2027 awards. (bestlawfirms.com)

If you’re an SME, founder or mid-market business

For most Australian SMEs, startups and privately owned businesses, I would not automatically start with Allens/HSF/Mallesons unless the matter is large, complex or high-stakes. You’ll often get better value from:

• Thomson Geer — strong national commercial firm; good for mid-market corporate, disputes and property.
• Mills Oakley — often practical and commercial; Legal 500 describes its Corporate/M&A team as focused on mid-market and international deals. (legal500.com)
• Hall & Wilcox — good broad commercial option, especially for mid-market businesses.
• Gadens — good for commercial, property, banking, disputes and mid-market work.
• Maddocks — strong for government, property, planning, construction and commercial work.
• Hamilton Locke — modern, fast-growing commercial firm; useful for corporate, finance, workplace and disputes.
• Kain Lawyers — particularly worth considering for corporate transactions and M&A where you want boutique focus.

My “shortlist by budget”

Premium / bet-the-company:
Allens, Gilbert + Tobin, HSF Kramer, Mallesons, Ashurst Perkins Coie.

Premium but broad full-service:
Clayton Utz, Corrs, MinterEllison.

Strong value for mid-market:
Thomson Geer, Mills Oakley, Hall & Wilcox, Gadens, Maddocks, Hamilton Locke, Kain Lawyers.

International overlay:
Baker McKenzie, DLA Piper, Norton Rose Fulbright, White & Case, Clifford Chance, A&O Shearman, Jones Day.

How to choose

For commercial law, the partner matters as much as the firm. Ask for:

• the proposed lead partner and senior associate;
• recent similar matters;
• hourly rates and whether fixed fees are available;
• conflicts check;
• who will actually do the work;
• a budget with assumptions;
• whether they are overqualified for the matter.

If you tell me your matter type—e.g. share sale, shareholder dispute, SaaS contracts, employment issue, property transaction, capital raise, insolvency, franchise, M&A, regulatory investigation—and your city/state, I can narrow this to a more useful 3–5 firm shortlist.

The commercial legal market in Australia is highly sophisticated, competitive, and has recently undergone some of the most significant structural changes in decades due to massive global mergers.

If you are a corporate executive, general counsel, or business owner looking for commercial legal representation, the market is broadly divided into the evolved "Big Six" global powerhouses, the elite premium independents, and the high-value mid-market leaders.

1. The Global Powerhouses (The Evolved "Big Six")

Historically, the Australian market was dominated by six domestic firms. Today, while these six remain the absolute elite tier for high-stakes, multi-billion-dollar transactions, major litigation, and complex regulatory matters, their global structures have evolved dramatically.

• Herbert Smith Freehills Kramer (HSF Kramer)
  • The Vibe: Preeminent for major litigation and market-leading M&A.
  • What to know: Formerly Herbert Smith Freehills, the firm completed a massive merger with US heavyweight Kramer Levin to form HSF Kramer. This makes them an absolute titan for cross-border transactions, especially for businesses with US, UK, or European touchpoints.
• Ashurst Perkins Coie
  • The Vibe: Dominant in infrastructure, energy, resources, and banking.
  • What to know: Ashurst completed a transatlantic merger with US technology and litigation powerhouse Perkins Coie to form Ashurst Perkins Coie. They are now a top choice if your business is navigating energy transition projects, major infrastructure, or tech-sector commercial disputes.
• King & Wood Mallesons (KWM)
  • The Vibe: The ultimate gateway to the Asia-Pacific region.
  • What to know: Melding the elite heritage of Australia’s Mallesons Stephen Jaques with China's King & Wood, KWM is a powerhouse for major corporate work, banking & finance, and cross-border investment. If you are dealing with capital markets or significant inbound investment from Asia, they are a default choice.
• Allens
  • The Vibe: High-prestige, traditional, and intellectually rigorous.
  • What to know: Allens operates in an exclusive global alliance with the UK "Magic Circle" giant Linklaters. They are the go-to firm for blue-chip ASX-listed companies on bet-the-company M&A, competition law, and complex banking matters.
• Clayton Utz
  • The Vibe: The largest proudly "independent" firm of the top tier.
  • What to know: Unlike HSF, Ashurst, or Allens, Clayton Utz has resisted merging with a global firm. They are heavily relied upon by both major corporate clients and federal/state government departments. They excel in major commercial litigation, construction, and government advisory.
• MinterEllison
  • The Vibe: A massive, full-service powerhouse.
  • What to know: By partner and lawyer headcount, MinterEllison is one of the largest firms in the country. They have a reputation for being exceptionally practical and client-focused, offering superb depth across everything from mid-market corporate deals to complex employment, real estate, and digital technology law.

2. The Elite Premium Independents (The Challenger Tier)

These firms are not technically part of the historical "Big Six," but they routinely go toe-to-toe with them for the country's most coveted commercial mandates. They are often preferred by clients who want top-tier talent without the overhead or potential conflict-of-interest issues of the massive global networks.

• Corrs Chambers Westgarth
  • The Vibe: Fiercely independent and highly aggressive in the market.
  • What to know: Corrs has successfully positioned itself as a true alternative to the Big Six. They recruit heavily from top-tier rivals and are frequently hired for high-stakes M&A, restructuring/insolvency, and class action defense.
• Gilbert + Tobin (G+T)
  • The Vibe: Entrepreneurial, tech-focused, and highly specialized.
  • What to know: G+T is widely considered the absolute best in Australia for technology, intellectual property, competition/antitrust, and private equity transactions. If you are a high-growth tech company, venture capital fund, or dealing with the ACCC, G+T is the market standard.

3. The Premium Mid-Market & Boutique Leaders

If your business is a large private company, a mid-cap ASX-listed entity, or you need highly specialized strategic advice where you want direct, hands-on partner contact, these firms are highly sought after.

• Arnold Bloch Leibler (ABL): A highly influential Melbourne and Sydney-based commercial boutique. They are famous for handling complex corporate tax, high-stakes commercial disputes, restructuring, and acting as trusted advisors to some of Australia's wealthiest families and private companies.
• Johnson Winter Slattery (JWS): A premium independent firm built on a "low leverage" model—meaning clients get heavily experienced, partner-led teams rather than armies of junior lawyers. They are exceptional in dispute resolution, energy, and corporate M&A.
• Mills Oakley & Hall & Wilcox: These are highly respected, fast-growing national firms. They are the go-to choices for general commercial work, employment, insurance, and real estate, offering top-tier capability at a more accessible price point than the global giants.

Which one should you use?

• For cross-border M&A and global reach (US/UK/Europe): Look to HSF Kramer or Ashurst Perkins Coie.
• For dealing with the ACCC, private equity, or tech/IP: Go to Gilbert + Tobin (G+T).
• For government-adjacent matters or major domestic litigation: Clayton Utz is highly recommended.
• For major mid-market corporate deals, property, or employment law with great value: MinterEllison, Mills Oakley, or Hall & Wilcox are the most practical everyday business partners.
