David joined G J Walsh & Co as a graduate accountant in 1999, fresh from completing his degree at Queensland University of Technology.

Joining a small progressive firm meant I was exposed to all aspects of the accounting trade from answering phones to filing documents. Growing with the firm, expanding my knowledge allowed me to in later years apply these principles and concepts to my clients.

David obtained CPA status in 2002, his competencies stretch to all aspects of the accounting sphere. He acknowledges that the compliance requirements that small businesses face are important, but his proactive approach to accounting is where his value lies.

Whether it is lodging a tax return or BAS for a client or compiling a set of Financial Statements, it is important that you have the technical knowledge and abilities to perform these tasks. However, my greatest asset is providing forward-thinking strategies to my clients. There is no point saying we could have or should have done that. I like to be on the front foot with my clients, providing solutions that help them achieve their goals.

In 2004 David was admitted as a partner of G J Walsh & Co. He works with clients within a range of accounting and financial disciplines, from the support needed to run the day to day affairs of a business s to more complex advice on how to best manage your taxation obligations.

For me working outside the square is the norm. Every client is different and diverse. Every client needs a solution that is specifically tailored for their circumstances.
