IBISWorld has estimated that industry revenue in 2009/10 was $21.8 billion.

The Australian Bureau of Statistics estimated $18 billion for the year 2007/08.

SmartCompany reports that IBISWorld is predicting that revenue in the legal services industry will be $26.3 billion by 2014/15.

This represents an average increase of 3.8% per annum or an additional $900m of revenue in each of the 5 years between 2009/10 and 2014/15.

On a macroeconomic level, this looks like a very healthy prognosis for the industry.
