South Australians are being urged to get smarter with their data and keep it out of the hands of scammers, as part of National Consumer Fraud Week.
State Business Services and Consumers Minister Gail Gago said identity theft and computer hacking were the most reported scams in the State.
"If you haven't taken action or thought about how to keep your private information secure, chances are you could be leaving it wide open for scammers to use for fraud," she said.
"As part of identity theft scams, people often receive a message claiming to be from a legitimate and well-known government, corporate or financial organisation requesting personal details to verify account details, pay a bill or win a prize.
"These types of scams are so common, it is likely most people think it's a nuisance and don't report it."
In 2013, South Australians lost about $5 million through scams.
To reduce the risk of falling victim to a scam keep your personal details secure; think twice about what you do and say online; keep your mobile devices and computer secure; choose passwords carefully; be wary of any request for your details or money and get a copy of your credit report.
Victims often suffer in silence because of the social stigma of falling victim to a scam, but are encouraged to report the scam at www. scamwatch.gov.au.
