Communications Minister Stephen Conroy is on the receiving end of another dishonourable award, after being dubbed Australia's dumbest politician in a magazine survey.

Zoo Weekly magazine conducted the online survey of 1200 voters to dub Senator Conroy the dumbest politician, followed by Family First senator Steve Fielding, and Opposition Leader Tony Abbott.

Senator Conroy scored 23 per cent of the vote following a series of gaffes on Labor's planned internet filter, a magazine spokeswoman said.

At the launch of National Cyber Security Awareness Week in Melbourne last June, Senator Conroy puzzled listeners by declaring: "There's a staggering number of Australians being in having their computers infected at the moment, up to 20,000, uh, can regularly be getting infected by these spams, or scams, that come through, the portal (sic)."

He later added: "If you were doing a banking transaction, or transmitting personal information, (Google) could have hoovered it up, sucked it up into their machine."
