The Centre Party, occasionally referred to as the Centre Movement, was a short-lived political party that operated in the Australian state of New South Wales. Founded in December 1933, the party's leader and most prominent figure was Eric Campbell, the leader of the paramilitary New Guard movement. That organisation had been established to oppose what its members perceived as the socialist tendencies of Jack Lang, the Premier of New South Wales, but declined following Lang's dismissal in early 1932.
The Centre Party contested five seats at the 1935 state election, and its candidates placed second to the United Australia Party (UAP) in two electorates, with almost 20% of the vote. However, it polled poorly in the other seats it contested, and disbanded shortly after the election. The Centre Party is generally seen as the political extension of the remnant of the New Guard, which had decreased in popularity and influence, and, under Campbell's leadership, had become increasingly inclined towards fascism.
With Eric Campbell, a solicitor and former officer in the Australian Imperial Force (AIF), as "principal founder", the New Guard was established in February 1931, open to "all loyal citizens irrespective of creed, party, social or financial position". Campbell's new organisation sprang out of the Old Guard, a "secretive" group of Sydney-based businessmen formed to oppose Jack Lang, the Premier of New South Wales and the leader of the Labor Party, which had gained power at the October 1930 state election. At the height of its power, the movement had been "overwhelmingly a middle-class organisation", and was, in general, "virulently opposed by workers and trade unions", with the exception of the Railway Service Association and other right-wing unions. Its main goal was achieved in early May 1932, when Lang's government was dismissed by Sir Philip Game, the Governor of New South Wales. Lang had refused to pay interest on loans from overseas creditors, and withdrew government money from bank accounts to prevent the federal government from appropriating it for that purpose. He was replaced as premier by Bertram Stevens, who led a coalition of the conservative United Australia Party and United Country Party to a landslide victory at the subsequent June 1932 state election. The anti-Labor parties together gained 31 seats and won just under half of the popular vote.
