Details of Tasmanians who voted from outside the state in recent elections have been stolen.Brigid Andersen: ABC
The personal information of thousands of Tasmanians has been leaked, the Tasmanian Electoral Commission (TEC) says.
TEC was yesterday told by the Spanish company Typeform that an unknown third party had accessed its servers and downloaded information.
Tasmanian Electoral Commissioner Andrew Hawkey said the electors were those who had applied for express votes at the recent state and Upper House elections.
"We've been informed that it includes the name, date of birth, email address and enrolment address of all the electors that applied for an express vote at the 2018 Legislative Council and state elections," he said.
"We don't have a figure as to exactly how many that is, we think it's probably in the vicinity of 4,000 electors."
The breach was identified by Typeform on Wednesday, and the company found that data collected through five forms on the TEC website had been taken.
Mr Hawkey said those who used express votes should be careful when opening emails from unknown addresses.
"The main risk is it may mean increased phishing emails, so electors should be wary of any unusual emails and should not look to click on any links are provided in emails that are not from people they know," he said.
"It's sensitive information, but it's not broader than that. It doesn't have any connection from the voting process.
"It was only the process of applying for express votes where this data was captured and it has no connection to the state roll or national roll."
The affected people will be contacted by the TEC in the coming days.
