Very interesting presentation here https://www.cio.com.au/article/268106/state_australian_cio on the breakdown of the Australian CIO. Top salaries appear to be in construction, architecturing and engineeering, followed closely by the mining industry and next financial services. Seems those who make the most dollars are business strategy focused leaders (average $236K), followed by functional heads (average $201K) and finally transformational leaders at (average  $191K).
