Members of the federal opposition have received advice on the risk of foreign interference from Australia's spy agency tasked with dealing with the ongoing threat of malevolent state espionage.
Parliamentarians in the Labor Party received a briefing on Tuesday, worked on in conjunction with the Australian Security and Intelligence Organisation, about the "unprecedented" risk of foreign interference in domestic politics.
Party members are now expected to report suspicious behaviour to national security advisers within the Opposition Leader's office or Labor's home affairs spokeswoman, Senator Kristina Keneally.
Where foreign actors are involved, politicians will need to report suspicious actions to ASIO directly.
The issued advice suggests members and senators plan their own events where possible, doing homework on relevant stakeholders and being as transparent as possible by recording all gifts and benefits.
"The simplest way to block foreign interference is to ensure transparency," the advice reads.
"Ensure that your processes are transparent - including making sure that gifts, events and other engagements are appropriately registered or recorded. And ask the same from your interlocutors.
"Unwillingness to meet your request for transparency should mean greater caution on your part."
It comes months after ASIO director-general Mike Burgess warned politicians make "attractive targets" for foreign adversaries.
"Almost every sector of Australian society is a potential target of foreign interference," Mr Burgess said last October.
"The level of foreign interference is high at all levels of government - it's actually higher at local than state and federal."
In response to the potential threat, Mr Burgess said ASIO would provide federal politicians with information on how to deal with it.
He committed to writing a letter that would outline the risks and provide high-level advice on what to look for.
