SENIOR levels of the Australian government are anxiously awaiting the release of the latest and most contentious tranche of WikiLeaks's secret US files.
The release is expected to contain secret US diplomatic cables that refer to politicians and important figures from around the world.
US Secretary of State Hillary Clinton even touched on the anticipated release during a phone call about the North Korean crisis with Foreign Minister Kevin Rudd on Thursday.

''It was briefly mentioned at the end of the conversation,'' a spokeswoman for Mr Rudd said.
National security advisor Duncan Lewis and the Secretary of the Department of Prime Minister and Cabinet, Terry Moran, are also believed to have been briefed about the documents.
While it remains unclear what is in the files - which date from 2003 to early this year - they could contain several potentially explosive issues, including the reasons behind the Howard government's decision to join the US-led invasion of Iraq and the detention of Australian citizens in Guantanamo Bay.
