5 Wentworth has its origins in Fifth Floor Chalfont Chambers. Established in 1932, led by Sir Garfield Barwick and Sir Cyril Walsh, and clerked by Edgar Marks, the chambers was a close-knit group of barristers that became an institution on Phillip Street.

It was Sir Garfield who promoted the foundation of Wentworth and Selborne Chambers as a permanent home for the New South Wales Bar. When he and his colleagues moved to the fifth floor of Wentworth Chambers in 1957, they were the first group of barristers to do so.

Since then, many of 5 Wentworth’s members have been appointed to judicial and executive office.

Today, 5 Wentworth maintains the same traditions of collegiality and excellence as when it was formed more than 90 years ago.
