Labor education spokesman Josh Willie says the Working Together program, capped at 120 hours, should be rolled out faster to help more children, their families and the childcare sector.

However, Education Minister Jeremy Rockliff says a staged approach is needed to allow the program to be refined.

The nation-leading program was launched a year ago and provides up to 400 hours of free early learning for eligible three-year-olds who would not normally engage in early learning programs.

Mr Willie said the government committed to making the program available to all eligible three-year-olds in 2020.

"The COVID-19 pandemic has caused great disruption and uncertainty for the childcare sector and there is now capacity to provide additional support to Tasmanian children and their families," Mr Willie said.

"COVID-19 has resulted in a big drop in attendance across the sector and it is now appropriate to remove the cap.

"Removing the cap on the program will provide more support for at-risk children and support the ongoing viability of childcare centres around the state with up to $10.5 million per annum being made available as the program is rolled out.

"The change in circumstances gives us the opportunity to revisit the program and work with childcare centres through an expression-of-interest process to speed up the rollout."

Mr Rockliff said given "Labor's long-standing and sustained opposition" to universal access to free pre-school for three-year-olds, he welcomed support for the program.

He said there were 120 places available for eligible three-year-olds this year through 19 service providers.

"This 'cap' is due to recommendations made when the pilot program was independently reviewed by Clear Horizons, and is not linked to childcare availability," Mr Rockliff said.

"Labor need to stop being lazy and read the report which recommends that it is important to continually reflect on learnings in order to refine and provide for continuous improvement.

"That's why the Government is taking a staged approach, to ensure we can continue the co-design process by learning and adapting as we go along."

Mr Rockliff said more places will be opened up every two years in a targeted way, with updated data sourced next year, to guide the selection process.
