About De Lisle

Who We Are

De Lisle Pty Ltd is a professional advisory and corporate services firm registered in Western Australia. Founded on the principle that sound governance underpins every successful enterprise, we deliver practical, outcome-focused counsel to organisations navigating regulatory complexity, strategic transitions, and operational challenges.

We operate from Perth, serving clients across WA and broader Australia. Our approach pairs deep familiarity with Australian corporate regulation — including the Corporations Act 2001, Australian Consumer Law, and state-level compliance regimes — with commercial pragmatism that turns compliance from a burden into a competitive advantage.

Our Values

Every engagement is guided by four principles that define how we work and the results we deliver:

• Integrity — We provide candid, impartial advice and never compromise on ethical standards.
• Rigour — Our work is methodical, evidence-based, and focused on defensible outcomes.
• Discretion — Client confidentiality is paramount; we treat every matter with appropriate sensitivity.
• Partnership — We invest in long-term relationships, not one-off transactions.

Our Approach

De Lisle works closely with boards, executives, and compliance teams to identify gaps before they become liabilities. We begin each engagement with a structured discovery phase, mapping regulatory obligations against current practices, and then deliver prioritised, cost-effective remediation plans.

We are not a generalist consultancy. Our focus is exclusively on governance, compliance, and strategic advisory — areas where precision and up-to-date regulatory knowledge matter most.
