“The three dimensions of 3D Corporate Law are the three things your lawyer usually only has one of.”

I spent nearly 30 years as a corporate lwyaer and then partner at firms including Baker McKenzie (Sydney and Hong Kong), Holding Redlich, Hall & Wilcox, and Allion Partners — advising on M&A, capital raises, governance and complex commercial matters across Australia, Asia and internationally.

Then I spent eight years inside a world-leading cybersecurity company as General Counsel, Director and Company Secretary. I sat on the board. I advised the CEO. I learned what founders, boards and investors actually need from a lawyer — not as an observer, but as a participant.

I hold a Masters of Taxation (Melbourne University), a Diploma of Applied Finance (Securities Institute), and a combined LLB (Hons) / BA (University of Tasmania). I use AI legal technology to deliver faster, more cost-efficient outcomes on document-intensive matters.

What clients say
The 3DCL Difference
David brings something rare to the table: the perspective of someone who has advised externally at the highest levels and has also genuinely sat in the GC chair inside a technology company. He understands the commercial pressures, not just the legal ones.
Founder & CEO
Deep-tech startup, Melbourne
We needed senior M&A counsel who could move at startup pace. David delivered partner-level quality on every matter and was available when it mattered most.
CFO
Public unlisted technology company
What sets David apart is that he thinks like a board member, not just a lawyer. His governance advice has been invaluable as we’ve scaled.

Why I have been quiet
I've been quiet on LinkedIn for a while. Here's why — and what's changed.
M&A
The Deal Terms That Matter More Than Your Valuation
Most founders focus on valuation first, legal terms second. Understandable - it's the number in the press release, the one that validates years of work. But after enough transactions, I'll say it plainly: valuation isn't what determines what you actually receive. The terms underneath it are. Many reach the table without a clear view of what those terms do.
