About us


Vidal O’Brien & Co. is a firm of chartered accountants established in 1936.

With offices in the Sydney CBD and Mona Vale on the Northern Beaches of Sydney we are able to provide a full range of accounting, taxation, audit and business advisory services for all business, superannuation and individual clients.

The firm has two principals – Graeme Dowsett and Geoffrey Smith – who have long and wide ranging experience in all aspects of accounting, taxation, superannuation and business services over many and varied business types.

Many of our clients have a long history of association with the firm and have referred new clients to us to enjoy the same level of service afforded to them.

Our staff members are an important link to the service we provide to clients.

It is with this in mind that we maintain regular staff training programs and encourage staff to develop an ongoing association with clients.
