The Australian Federal Police (AFP) say WikiLeaks has broken no Australian criminal laws.
Attorney-General Robert McClelland says the government has received advice from the AFP over the WikiLeaks leaking of official United States government documents.
Mr McClelland said the AFP noted a number of offences which could be applied in the circumstances, depending on whether all elements of the offence could be proven.
Based on the information available to date, the AFP has not identified any criminal offences where Australia has jurisdiction and as a result have not commenced an investigation, he said.
"The government referred the matter to the AFP as it was prudent to examine whether any Australian laws have been broken," he said in a statement.
"As has previously been stated, given the documents published to date are classified by the United States, the primary jurisdiction for any investigation into the matter remains the United States.
"The government remains extremely concerned about the unauthorised and irresponsible distribution of classified material."
The Attorney-General's Department referred WikiLeaks and its founder, Australian Julian Assange, to the AFP following the release of the first batch of US embassy cables containing classified information on the WikiLeaks website.
The AFP said on Friday it examined material relevant to potential Australian offences to determine whether an official investigation was warranted.
"The AFP has completed its evaluation of the material available and has not established the existence of any criminal offences where Australia would have jurisdiction," it said in a statement.
"Where additional cables are published and criminal offences are suspected, these matters should be referred to the AFP for evaluation."
