WikiLeaks and Julian Assange have been the subject of intelligence exchanges between Australia and the United States for more than two years, the Department of Foreign Affairs and Trade has revealed.

The WikiLeaks publisher was also the subject of Australian intelligence reporting from Washington shortly before he sought political asylum in Ecuador's London embassy.

In a freedom of information decision yesterday, Foreign Affairs confirmed to Fairfax Media the existence of an intelligence report concerning WikiLeaks and Mr Assange cabled to Canberra from Australia's Washington embassy on June 1.

Mr Assange, who had been unsuccessful in his legal fight to avoid extradition from the United Kingdom to Sweden to face questioning about sexual assault allegations, sought political asylum in Ecuador's London embassy 18 days later.
