Deloitte Australia has lost market share among
Australia’s 100 largest listed companies (ASX100), according to
Australian business publication BusinessDay.

Since 2004, Deloitte has lost market share in
terms of the number of companies it audits and the share of the
market those audits represent. In 2004, Deloitte Australia had 10
clients among ASX100, while in 2011 it has seven.

The firm attributed the loss to a shift in
strategy that focuses more on advisory services.

Depsite this, Deloitte has picked up big
ticket clients recently, including Leighton Holdings, Incitec Pivot
and Sigma Pharmaceuticals.

Deloitte Australia said it has won the most
new ASX600 clients in the past fiscal year.

Ernst & Young (E&Y) gained the largest
chunk of the ASX100, moving from 24 clients in 2004 to 32 in
2011.

The two largest firms PwC (33 clients) and
KPMG (30 clients) have maintained a steady client base among the
top 100 since 2004.
