David Walker is recognised as a leading corporate lawyer in australia, combining partner‑level transactional experience with an uncommon inside‑the‑business perspective. As Principal of 3D Corporate Law, he positions himself as “the lawyer who has been in your seat”, bringing almost four decades of senior corporate practice, eight years as in‑house general counsel and board experience for listed and private companies.
Walker trained with Baker McKenzie and progressed to senior partner and principal roles across major Australian and international practice settings. His external practice concentrated on M&A, capital markets, governance and complex commercial transactions across Australia, Asia and internationally before moving in‑house.
He later served eight years as General Counsel, Director and Company Secretary of a leading cybersecurity company (VeroGuard, now Keyek), and has held ASX directorships, including with eChoice Limited. Walker holds a Master of Taxation (University of Melbourne), a Diploma of Applied Finance (Securities Institute) and a combined LLB (Hons)/BA (University of Tasmania). These qualifications underpin a practice that bridges structuring, securities and corporate governance in complex transactions.
As a corporate lawyer in Australia, Walker concentrates on end‑to‑end deal work: mergers & acquisitions, capital raising and IPOs, shareholder and unitholder arrangements, joint ventures and corporate structures and restructures. His transactional offering includes structuring, due diligence and foreign investment and competition law merger compliance, for both public and private targets.
3D Corporate Law specialises in sectors where governance, IP and regulatory risk are most acute: technology and cybersecurity, deep‑tech and med‑tech start‑ups, agribusiness, finance, IT&T and energy & resources. The practice also provides fractional outsourced general counsel services, delivering GC‑level advice to growth companies that do not require a full‑time in‑house lawyer.
Walker’s defining strength is an “inside‑out” approach: decades as an external adviser followed by senior in‑house roles give him practical commercial judgment as well as technical depth. He emphasises building governance frameworks, clean cap tables and pragmatic documentation that let clients move quickly without compromising legal protections. This combination is pitched to founders, boards and investors who value counsel that understands operational constraints and investor expectations.
He also adopts modern legal technology to streamline document‑intensive matters, improving efficiency and cost predictability, an increasingly important differentiator for businesses that want partner‑level skills with startup tempo.
Walker’s career includes senior roles at notable law firms and in‑house appointments that translate into transaction‑level credibility: senior corporate leadership at Baker McKenzie, subsequent senior partnership and principal roles in the Australian market, and long‑term GC experience at a globally oriented cybersecurity business. These roles underpin his experience on cross‑border M&A, capital markets work and ASX governance.
Industry recognition includes listings in respected legal directories and market guides. He was named in Asialaw Leading Lawyers across multiple years and has been recommended in specialist guides for energy & resources lawyers in New South Wales, reflecting a sustained market reputation for transactional work in that sector. Walker regularly publishes practical commentary on M&A, governance and cybersecurity law through his professional channels.
Corporate law in Australia sits at the intersection of ASX listing rules, corporations law, tax, foreign investment controls and competition regulation. Practical issues for businesses include navigating disclosure and governance obligations, FIRB and ACCC notifications where relevant, and structuring cross‑border deals to manage tax and securities consequences. Specialist corporate advice is critical to allocate deal risk, design realistic commercial protections and ensure enforceable governance as a company scales.
Recent regulatory developments and greater scrutiny on national‑security and competition grounds make pre‑transaction planning and informed legal structuring more important than ever. For founders and boards, getting these layers right up front reduces transaction friction, preserves value and shortens timetables for capital raisings or exits.
Walker approaches engagements with a focus on outcomes: advising how to get to “yes” while putting in place protections that reflect commercial realities rather than theoretical worst‑case scenarios. He offers both discrete transaction work and ongoing outsourced GC support, tailoring service levels to a company’s stage and risk profile.
Clients report value from his board‑level thinking: governance advice that anticipates investor scrutiny, documentation that facilitates fundraising and exit‑oriented drafting that preserves founder and investor value. This pragmatic, governance‑forward model is aimed at minimising operational disruption while protecting the business’s strategic options.
Businesses seeking a corporate lawyer in Australia, particularly technology and cybersecurity companies, deep‑tech start‑ups, ASX‑listed entities, and firms in energy & resources, will find Walker’s blend of private practice rigour and in‑house experience immediately relevant. His practice is tailored to founders, boards, CFOs and investors who require senior counsel that moves at commercial speed and understands investor horizons and governance expectations.
