Since its inception, the firm has grown significantly, expanding its presence with offices in Sydney, Brisbane and Melbourne while, building a reputation as a trusted adviser to national and international clients.

Over the past 125 years, Colin Biggers & Paisley has evolved from a boutique Sydney practice into a leading national legal practice. This growth has been shaped by strategic mergers with esteemed firms Monahan & Rowell, Hemming + Hart, and Logie-Smith Lanyon, further enhancing their expertise. Today, Colin Biggers & Paisley is recognised as a trusted adviser in commercial law, with deep specialisation across the insurance, property, construction, transport and logistics, education, corporate advisory, technology, aged care, faith-based enterprises and government industries.

Nick Crennan, Managing Partner, stated that “Reaching 125 years is a milestone of immense significance, and we are  proud of the legacy we have built. Throughout our history, we have been steadfast in our commitment to excellence, integrity, and service—values that have distinguished us as leaders in the legal profession. This achievement is a testament to the dedication of our current partners, the vision of those who came before us, and the many people who have contributed their expertise and effort to our practice."

The firm’s early leaders instilled a deep commitment to community and social responsibility—values that remain central to Colin Biggers & Paisley’s culture today. In 2016, this dedication was formalised with the establishment of the Colin Biggers & Paisley Foundation, which provides pro bono legal services, volunteering initiatives, and charitable contributions. Since its inception, the Foundation has contributed 64,168 hours of pro bono work, 5,945 volunteering hours, and donated over $2 million in support of marginalised communities.

Nick Crennan continues: "As we celebrate this 125-year milestone with a special event on 6 March, we also reflect on the responsibility that comes with our profession. We never forget that, as lawyers, we hold a privileged licence in society, and with that privilege comes a duty—to support those in need and give back to the communities we serve. Our commitment to this responsibility is stronger than ever, and it will continue to guide us into the future."

At the intersection of experience and innovation, Colin Biggers & Paisley are using technology to train lawyers and offer clients smarter solutions. Deputy Managing Partner, Dr. Andrew Murray commented, "We have always been at the forefront of technological innovation. So much so that when existing technological solutions have not met our clients' needs, we have a proven track record of developing our own platforms which do."

The firms robust strategy for the deployment of technology makes them a market leader in the technology law field. Driving the use of emergent tools to enhance engagement, Colin Biggers & Paisley empower their clients to improve workflows and generate efficiencies through the use of AI tools such as CoPilot and Cicero. 

Murray commented further, saying "Today, we are more than just lawyers—we are strategic partners, problem-solvers, and drivers of progress, committed to building a stronger future for our clients, colleagues, and communities. As we celebrate 125 years, we honour our legacy while embracing the opportunities ahead."

As Colin Biggers & Paisley marks its 125th anniversary in 2025, this milestone reflects the firm’s enduring commitment to growth and legal excellence. Looking to the future, the firm remains dedicated to investing in its people through strategic hires and promotions while deepening its community impact and enhancing its outcome-focused solutions.
