About us

TWS Accountants

TWS Accountants Pty Ltd was founded in 2002 through the incorporation of the long-established practice, Thomas Tsang & Co., which began in 1991. The firm was formed by three partners—Thomas Tsang, Sunny Wong, and Douglas Shim—each a qualified CPA Australia member. Collectively, they bring decades of experience in accounting, taxation, and business advisory services. Fluent in English, Mandarin, and Cantonese, the partners have cultivated a diverse client base across Brisbane and beyond.

With its roots on Brisbane’s Southside, TWS Accountants has proudly served individuals, investors, and businesses across a wide range of industries for over 15 years. Our clients span local, interstate, and international locations, supported by modern technology that enables seamless communication and efficient service delivery regardless of distance. As tax laws and regulations continue to evolve, we remain committed to providing timely, reliable, and practical advice—helping clients stay compliant and confident in their financial affairs.

At TWS Accountants, we believe great accounting goes beyond numbers. We value strong client relationships and tailor our services with cultural understanding and industry insight. Our commitment to quality, professionalism, and long-term success drives everything we do. We take pride in being a trusted advisor to our clients, offering not just technical expertise but also genuine care, so they can focus on what they do best—while we take care of the rest.
