Overall, salaries for IT professionals increased 12 percent when compared to the same period last year. Rates for contractors increased overall as well, as did the average length of the contract.

An application development manager is on an estimated salary of between A$95,000 (US$73,943) and A$220,000 per annum, a 15 percent increase compared to 12 months ago. Both security and storage professionals are now earning between A$100,000 and A$180,000 per annum, a salary increase of between 10 and 15 percent.

According to the report Australian employers are looking overseas to fill the domestic drought as not enough skilled Australians are coming through the IT ranks, according to Andy Cross, managing director of technology recruitment firm Ambition.

Cross said he cannot confirm if the government is hoarding all the labor resources but demand for security professionals continues to be positive. The number of compliance programs growing in the financial sector means a lot of these skills are snapped up at higher prices in the private sector.

"Government is not comparable with the private sector, and fortunately, contractors are mercenary when it comes to dollars," Cross said.
