That same year she auditioned for Macquarie's radio station 2GB and gained an A-Grade pass, which meant she started acting for 2GB almost immediately.

On 2UE she won the important role of Angel White in Hagen's Circus, written by Max Afford; she was in episodes of I Hate Crime, starring Ken Wayne as Larry Kent; and she was part of the team working with comedian Mo McCackie in Cavalcade.

He obtained scripts of Blondie, an American show based on Chic Young's comic strip of the same name, and set about producing an Australian version of them.

Willie Fennell played Dagwood Bumstead, Blondie's rather put-upon husband, but competition for the title role was very keen.

Blondie went to air in November 1951, but its run was not to be a long one, as the threat of legal action from the United States brought it to an abrupt end.

Norton did a good deal of radio work for the ABC: Anna in Clifford Odets' Golden Boy; Letta in Arthur Miller's Death of a Salesman, starring Edward Howell; roles in Rex Rienits' Wide Boy, Elmer Rice's Counselor-at-Law, and the serial Stranger Come In, written and produced by Max Afford.

Commenting on her performance in Anna Lucasta, Breen wrote: "Kerry Norton was noteworthy for her devastatingly real depiction of a waterfront harlot."
