By mid-1974, Australia was in an economic slump. The 1973 oil crisis had caused prices to spike and, according to government figures, inflation topped 13 percent for over a year between 1973 and 1974. Part of the inflation was due to Whitlam's desire to increase wages and conditions of the Commonwealth Public Service as a pacesetter for the private sector. The Whitlam government had cut tariffs by 25 percent in 1973; 1974 saw an increase in imports of 30 percent and a $1.5 billion increase in the trade deficit. Primary producers of commodities such as beef were caught in a credit squeeze as short-term rates rose to extremely high levels. Unemployment also rose significantly. Unease within the ALP led to Barnard's defeat when Jim Cairns challenged him for his deputy leadership. Whitlam gave little help to his embattled deputy, who had formed the other half of the duumvirate.
