Seven decades of trusted counsel. Evolved for what’s next.
GILLIS+Co. brings together a senior team of lawyers and advisors with deep roots in the Sydney legal and business community. The relationships, expertise and commitment to clients that have defined this team for decades remain unchanged. What has changed is the platform from which we work.
The Gillis name has been part of Sydney’s legal landscape since the 1950s. That heritage, built on integrity, sound judgment and a genuine focus on client outcomes, is the foundation on which GILLIS+Co. stands. We carry it forward with the same values and a clear view of where the profession is heading.
We are lawyers — but we are advisors in equal measure.
Our value to clients reaches well beyond the legal brief. Drawing on deep commercial experience, established networks and a real understanding of how businesses operate, we offer more than counsel: clear, strategic guidance at the moments that matter most.
Legal expertise and commercial judgment, working together.
The most valuable moments in a client relationship are rarely just legal. They are moments of decision where the right advice requires not only knowledge of the law, but an understanding of the business, the relationships and the consequences that follow. That is where GILLIS+Co. is built to operate.
