Deloitte Australia has grown annual revenue by 18% to A$1.1bn ($1.1bn) in the year to 31 May 2012 – the first time it has broken the A$1bn mark.
Deloitte chief executive Giam Swiegers said the increase in revenue resulted from investments in analytics, technology and economics as well as an influx of audit clients.
Deloitte has been on a rapid rise in the past five years, doubling in size. Only in 2007, the firm posted revenue of A$626m and in most of the subsequent years has outgrown its larger Big Four rivals.
Key sectors for the firm include financial services, energy and resources, the public sector, telecommunications, media, technology, property and tourism.
By July, Deloitte predicts it will have 520 partners and 4,900 staff.
“Our investment in partner talent clearly demonstrates our confidence in the Australian economy despite the current volatility in Europe and our commitment to our 2015 strategy to grow the firm,” Swiegers said.
