Philip Delahunty

Senior Partner

Phil was a founding partner of RSD in 1995. Prior to that, he was in the profession as an employee and partner for 12 years. He believes it's important to have a clear understanding of our client's business, and how they seek to achieve their objectives.

Socialising, including a large family, dominates the non-work time. Community time, travel and sports of all types (love Aussie Rules, Cricket, getting out to the lake in the boat, and Motor Racing) are the main time wasters. In my mind, I can do anything. But the truth is - it's mostly spectating these days.

Phil holds a Bachelor of Business (Accounting), is a member of the Institute of Chartered Accountants Australia and New Zealand, and Registered Company Auditor and Registered Superannuation Fund Auditor.
