Archie Galbraith Cameron

Labor legislated for proportional representation in the Senate in 1948, and they required voters to number every box.

Indeed, a Liberal MP, Archie Cameron, proposed that voters should only need to number as many boxes as there are seats to fill, and this was rejected out of hand by the Attorney-General, H.V. Evatt, who expressed concern about votes exhausting when they could influence the result.

There was an uptick in informal voting for the Senate at the 1949 federal election under the new system.

There was no change in the demands on the voter.
