History of Deloitte Australia

Deloitte Australia has grown from a firm known as Yarwood Vane and Co. Established in 1891 it won work in Sydney and elsewhere and became a leading entrepreneurial firm.

In 2006, well-known mid-market accounting firm Horwarth's NSW practice joined Deloitte Australia.

Up until 1979, partners used to sign reports on Yarwood Vane letterhead, Deloitte letterhead or Haskins and Sells letterhead depending on the nationality of the work. Dulhunty Grant and Co, Irish Young and Outhwaite and other well known firms merged into Yarwood Vane and by 1980 the name of Deloitte Haskins and Sells was being used.

In 1989, Deloitte Haskins and Sells Australia became a member firm of Deloitte Ross Tohmatsu International and the Australian firm took the name Deloitte Ross Tohmatsu. It wasn't until March 1993 that the partnership adopted the name, Deloitte Touche Tohmatsu. Although Touche Ross Australia decided not to become a member of Deloitte Touche Tohmatsu International, many of its partners and staff chose to leave Touche Ross and join our firm.

In December 1993 Deloitte Touche Tohmatsu merged with Duesburys, then the largest second-tier firm in Australia. This merger occurred in Sydney, Melbourne and Brisbane.

In July 1994, Deloitte Touche Tohmatsu merged with BDO Nelson Parkhill in Western Australia, strengthening the Perth office of Deloitte Touche Tohmatsu. In July 2005, Deloitte Touche Tohmatsu merged with PKF in Adelaide, Darwin, Alice Springs and Katherine. In July 1994, we merged with Haly and Co in Brisbane and Kidsons-DFK in Papua New Guinea.
