"The West Australian Industrial Relations Commission has decided to increase the full time adult minimum wage and state awards by $20 per week.
This means the minimum full time wage in the state will increase to $665.90 per week from July 1.
All state award wage rates will also increase by $20 per week.
The decision comes after last week's three per cent increase to the national minimum wage by the Fair Work Commission to $640.90 per week."
