The total 15% increase will be staggered over the next two years, and is dependent on centres promising not to increase their fees by more than 4.4 per cent over the next year.
Childcare workers are set to receive an extra $103 a week from December, and then an additional $155 more per week from December 2025.
Education Minister Jason Clare says to ensure the 15 per cent increase gets into the hands of educators, centres will need a registered industrial agreement with the Fair Work Commission and there will be a legally enforceable agreement with the Department of Education and providers to ensure they abide the 4.4% cap.
