47 per cent of Australians provide inaccurate information about themselves to websites as a privacy precaution, a paper by the Australian Communications and Media Authority has found.
The report is on privacy and personal information.
It found that More than a third (36 percent) of respondents said they would rather not use a service than give inaccurate information.
Only 17 percent said they are happy to provide accurate data about themselves.
"Privacy remains an enduring concept in the media and communications environment," ACMA chairman Chris Chapman said.
"Citizens remain highly sensitive to intrusions on their privacy and the mishandling of their personal data.
62 per cent of respondents identified security concerns, unauthorised access to or misuse of personal data as their top concern.
"Effective protection of personal data in the digital economy is likely to require a mix of regulatory and non-regulatory measures that are tailored to the specific contexts in which privacy concerns arise,” Chapman said.
"However, Australian citizens and industry would benefit from a coherent regulatory framework which facilitates logical and predictable privacy outcomes."
The ACMA said respondents were concerned about how information about their location was collected and stored.
