The economy continues to show signs of struggling, with the jobless rate increasing in February after the nation shed 15,000 part-time workers.
The Australian Bureau of Statistics reported the unemployment rate rose by 0.1 percentage point to 5.2 per cent.
While full-time employment was steady at 8.1 million there was a 15,400 drop in part-time workers.
The number of people out of work increased by more than 16,000 to 632,000 even though the participation rate - the number of people looking for work or in it - dropped by 0.1 percentage points.
Despite the national increase, the unemployment rate across WA fell by 0.1 percentage points to 4.1 per cent.
The number of full-time workers in WA rose by more than 16,000 to an all-time high of 912,000.
That helped to offset a drop of 12,000 in the number of part-time workers.
