The unemployment rate fell 0.4 of a percentage point to 6.9 per cent in the December quarter, as the number of people leaving the workforce fell faster than the number of jobs available, according to the household labour force survey. Economists were picking a headline rate of 7.1 per cent in a Reuters survey.
The participation rate fell a record 1.2 percentage points to 67.2 per cent, the lowest level since September 2004, while employment shrank 1 per cent. Economists were expecting a participation rate of 68.5 per cent and quarterly jobs growth of 0.4 per cent. The number of people not in the labour force climbed 3.8 per cent in the quarter.
