Early years


In Melbourne in 1895, an aspiring and talented accountant pursued his dream of establishing an accounting practice which would advance the interests of the business community through the provision of outstanding accounting services.

His name was William Buck and his practice reflected his vision and dream.

The firm William Buck attracted a wide range of clients, from small family businesses to large corporations.


“It is not for us to define excellence. The quality of our work will be decided by the people and businesses that we help.” Mr William Buck, Founder.


William was still not entirely satisfied and wouldn’t be until he fulfilled his next goal of founding the first accounting school in Victoria. He wanted to ensure that the accounting profession was committed to excellence, and this he did, with his school later becoming what we know today as the CA Program.

A century of excellence

In the early 1920s, William’s son, William Buck junior, took over where his father had left off, and throughout the rest of the 19th century, he built on the tradition of providing accounting services of the highest quality.

With seven integrated business units, and more than 90 staff and eight partners, William Buck was one of the leading accounting firms in Victoria.

William Buck signed a co-operative agreement with one of the largest consultancy firms in China during this time. Under a new agreement, William Buck began to offer a range of services for businesses wishing to invest in China, and for Chinese businesses wanting to set up the most efficient and effective corporate structure within Australia.
