Garry Widdup FCA

Garry J Widdup, B. Com, FCA, FGIA, CPA is the founding Principal of the firm and possesses over 40 years experience within the industry. He is a Fellow of the Institute of Chartered Accountants Australia (FCA), a Certified Practising Accountant (CPA), a Fellow of the Governance Institute of Australia, a Registered Company Auditor, and a Registered Tax Agent.


Prior to founding Widdup Barilla, Garry had twelve years experience with Sydney-based International Chartered Accountancy firms including Price Waterhouse Coopers and BDO covering all facets of accounting, taxation and auditing


After accumulating a wealth of education and experience Garry turned down big-city partnership opportunities for a desire to establish and administer his own practice


In 1990 Garry was joined in the practice by Mr. Joseph Barilla F.C.A. and they practised together for 19 years prior to Joe’s sad and untimely passing in 2009.


Many of Garry’s clients have continued to engage his services since he commenced practice in 1982 and his clientele and business has continued to grow. His clientele is diversified and range from small to medium enterprises to some of the country’s top medical practitioners and surgeons, Australian sporting legends, leading manufacturers and landmark hotels.


Garry has been married for 42 years and is the father of three daughters. Recreationally Garry enjoys boating, fishing, snorkelling and kayaking. Being a South Sydney Rabbitohs supporter, his long term wait for a premiership win was finally rewarded in 2014 with hopefully more to follow in the next few years.
