The two main surveys in the industry for publication numbers are the ABC circulation and the Roy Morgan Readership survey.
The emphasis is different as the ABC deals with circulation while the Roy Morgan deals with the readership. An example might be a newsagent would be interested in circulation while advertisers mainly in readership.
Roy Morgan readership survey has just been released and is available here.
The two results seem fairly similar.
Part of the problem I think for news suppliers in 2009, is that we lacked enough big major news that are required to generate interest which drives sales.
