The Australian University sector employs over 110,000 staff and has a student population of over 830,000. A summary of these statistics is available on the CAUDIT website: http://www.caudit.edu.au/statistics.
The figures are actually compiled by the Department of Industry, Innovation, Science, Research and Tertiary Education (DIISRTE) with full figures available on the department website: http://www.deewr.gov.au/HigherEducation/Publications/HEStatistics/Publications/Pages/Home.aspx.
Using published data such as Full Time Equivalent (FTE) staff and Effective Full Time Student Load (EFTSL) is common in CAUDIT agreements. These figures can be used to provide a reasonable basis for charges, with a per-FTE and/or per-EFTSL rate being used.
The CAUDIT membership has a total of 6,500 IT Professionals employed.
