However, the discrepancy has been noted in the survey, which says the "reduction in electronic attacks, coupled with the reduction in the "readiness-to-protect" factors is a puzzling combination" that may be described by the increased sample poll to include sectors not as heavily reliant on IT, such as manufacturing.

The sample poll in the manufacturing sector increased eight percent in 2006, from 11 percent in 2005.

Convictions still don't measure up

Only 19 percent of all respondents (389 in 2006, 181 in 2005) who had reported a computer crime to law enforcement said it resulted in charges being laid.

Kevin Zuccato, managing director of the Australian High Tech Crime Centre, said 19 percent is a very good figure, considering what investigators are up against.
