Teachers are calling on the NSW government to ditch a plan to restrict pay rises to the highest performing teachers.
Premier Dominic Perrottet will propose the pay block in a speech at Western Sydney University on Wednesday.
NSW Teachers Federation president Angelo Gavrielatos said the premier's proposal would be an effective pay cut.
"We need a comprehensive plan that address uncompetitive salaries and unsustainable workloads to stop the shortages and secure the teachers we need for the future," Mr Gavrielatos said.
Australians are facing rising cost of living pressures due to inflationary pressures.
Teachers have gone out on strike twice this year as they push for better pay and conditions in the wake of the COVID-19 pandemic.
The state government recently proposed a three per cent pay rise, below the current rates of inflation meaning the boosted wages wouldn't keep up with increased daily living costs.
In part of his speech, Mr Perrottet will reportedly say the current teacher's pay model "doesn't make sense".
"We have a system in which the best teachers and the worst teachers are, for the most part, paid and treated the same," he will say.
The NSW government will release a discussion paper to lay out how the new system would work, which would see subject matter experts paid up to $180,000 per year.
Mr Perrottet will also say he wants more "reading, writing and arithmetic, less puppetry, politics and wearable art".
In another part of Mr Perrottet's speech, released early to media outlets, the premier will say parents will get a new advocacy team inside the state's education department.
It will give parents an alternative way to resolve issues with schools.
"We want those concerns to be resolved directly ... but sometimes that can't happen," the premier will say.
