About Us


BDWelsh & Co was established in 1992 in Sydney to provide professional accounting and business services. We help companies in Australia as well as those from overseas setting up in Australia.

The firm’s bilingual and multilingual team represents outstanding skill and knowledge across our core services; Accounting, Audit and Assurance, Business Set Up, Migration Services and Taxation.

Our principal, Brian Welsh, CA, is a fluent Japanese speaker while other staff speak Japanese, Mandarin and Spanish. We keep up with our professional areas of expertise both here and internationally.

BDWelsh & Co offers a unique blend of strengths – the ability to provide our clients with professional services on a par with the Big 4 accounting and business services firms but with far greater personal attention.

Brian Welsh and our senior team stay involved in each client assignment from beginning to end. We also draw on the strengths of the entire team to collaborate on client matters.

In addition to our highly skilled team, we draw on our well-established networks to help clients. This includes law firms, business consultants, real estate agents and specialists in the areas of mergers & acquisitions and research and development.

BDWelsh & Co has extensive experience helping businesses from Japan. We also work with clients from other countries and maintain strong international relationships with accounting firms in Japan and Colombia.

We are located in Chatswood, Sydney’s third largest commercial district, about 8 km north of Sydney’s Central Business District.
