Australian government representatives have recently met US officials in Washington to discuss concerns over the forthcoming internet censorship regime raised by the US ambassador to Australia and the US State Department.

Communications Minister Stephen Conroy has come under increasing pressure to reveal the content of discussions with US officials after the US State Department said it had "raised concerns" with Australia and the US ambassador said net censorship was not necessary.

On ABC's Q&A program this month, US ambassador Jeffrey Bleich said the same goals set out by the government on cyber safety could be achieved without censorship. Bleich said the US was willing to "share our efforts" with Australia.

He said: "The internet needs to be free. It needs to be free the way we have said the skies have to be free, outer space has to be free, the polar caps have to be free, the oceans have to be free. They're shared resources of all the people of the world."
