Career
He later managed a clothing store in Cobar before moving to Tumut in 1919 to open a clothing store of his own. Fuller successfully contested Hume at the 1943 election as part of the Curtin Labor landslide. In his maiden speech, Fuller stated his full support for the nationalisation of airlines and banks and that "the Commonwealth Parliament should assume supreme control of land and all other national resources, including money." However, Fuller was not averse to criticising Labor policy when it detrimentally affected his constituents, such as in April 1944 when he accused Labor leaders of stifling the economic development of the New South Wales Riverina district (which encompassed Hume).
In parliament, Fuller quickly gained a reputation as one of its quirkier members.
A tall, thin man with a long neck, Fuller was nicknamed "Pilsener" due to his resemblance to long thin pilsener bottles. His inclination for long, loud speeches led one reporter to write that Fuller was "at times likely to rant about things he was passionate about without thought for tact", while his idiosyncratic dress sense became a subject of mirth for the Canberra Press Gallery.
Following his successful re-election in 1946, Fuller was given the official job of Government Whip and the unofficial job of chief heckler of opposition speakers, particularly Jack Language. In 1951, Fuller regained Hume by 796 votes but lost it to Anderson again by 1715 votes in 1955 before regaining it again from Anderson by 704 votes at the 1961 election.
By the 1963 election Fuller, in failing health, no longer had to face his old opponent Anderson but had lost much of his support base, with longtime supporter The Tumut and Adelong Times urging a vote against "our grand old man of politics".
