The former Australian health minister, and now Attorney General, explained the "large and very graphic" health warnings that will appear on cigarette packets.

Her own father died from cancer when she was 10-years-old, and she told Martha Kearney on the The World at One how children have pressed her to bring in a complete ban on smoking.
